3 CRD05-. GENERAL INFORMATION The CRD05- reference design can be used for the development of CNR or motherboard PC audio systems that use the CS05. The CRD05- can also be used in conjunction with the CRD05- to develop audio systems for PC notebook computers with digital docking stations. The CS05 is an AC 97 audio codec with the same great features as our other Crystal Clear audio codecs and some unique features especially designed for PC notebook computers. These include I S outputs for digital docking and a ZV port for digital audio inputs. For additional information on the CS05 audio codec, see the CS05 Datasheet.. SCHEMATIC DESCRIPTION This section describes the CRD05- schematics shown in figures through 7. These schematics are also available in the CMK05- manufacturing kit as ORCAD version 7. files.. Block Diagram The block diagram shows the interconnections between schematic pages. The schematic is divided into six blocks: the CS05 Audio Codec, Analog Inputs, Docking Interface, Analog Outputs, S/PDIF Optical Output, and CNR Connector.. CS05 Audio Codec Figure shows the CS05 and its associated circuitry. The CS05 communicates digitally to the audio controller or core logic through a five wire bi-directional.88 MHz serial interface called the AC-Link. The AC-Link may require series termination resistors. These resistors should be located close to their respective signal source. The BIT_CLK and SDATA_IN signals are driven from the CS05, while the SDATA_OUT, SYNC, and RESET# signals are driven from the controller. RESET# does not require serial termination. The CS05 has anti-alias filters for the ADCs that require external filter capacitors on AFLT, AFLT, and AFLT (pins 9, 0, and ). Each pin has a 000 pf /COG capacitor to analog ground. /COG capacitors are used to minimize audio distortion. The internal ADCs, DACs, and AC-Link operate at a fixed 8 khz sampling rate. The CS05 is clocked by a.576 MHz ( 50 PPM) crystal. This design provides two population options for different crystal footprints. Footprint Y is for CA- 0 miniature crystals and footprint Y supports standard HC-9S package. Footprint Y is for an optional clock oscillator. Many notebook computers have a ZV or Zoomed Video port that carries PCM audio data in I S serial format. The CS05 has a built-in ZV port input connected to JP5. The CS05 has seven multi-purpose pins that primarily support I S serial inputs and outputs for digital docking or multi-channel audio. These signals are tied to a a 5x (0. inch center) breakout connector. Pin Function LRCLK SDO 5 DSSD 7 DSSD 9 DSDD Even Pins Digital Ground Table. Serial I/O Breakout Connector. Analog Inputs The CRD05- has four stereo and three mono analog audio inputs as shown in figure. The inputs for VIDEO, AUX and LINE are passed through a divider circuit that reduces the voltage by 6 db to allow connection of line level sources up to Vrms. The 00 pf capacitors are provided on Line In and Mic In for EMI suppression. The capacitors may be removed if EMC testing determines they are not required.

4 CRD05- MIC IN and PC BEEP IN are AC coupled through 0. µf capacitors. All analog other analog inputs are AC coupled through. µf electrolytic capacitors to minimize the low frequency roll-off. The internal CD audio connection utilizes a pseudo-differential interface with CD as the common return path for both the left and right channels. This arrangement will reduce any common mode noise picked up by the CD signal path. The MODEM AUDIO connector provides monitoring of modem audio signals during modem dialing and connecting. This connector has both the modem audio input and output signals. The modem input voltage is divided by 6 db and can accommodate a line level source up to Vrms. The output is connected to the CS05 MONO_OUT pin. The maximum output voltage is Vrms. The MIC IN circuit complies with PC-99 requirements for both microphone phantom power and optional frequency response roll-offs. Phantom power for the microphone is derived from the 5 V analog supply and filtered by R, R5, C7, and C8. The db roll-off points located at 60 Hz and 5 khz. The PC BEEP input connector routes the computer beep tones to the CS05. The CS05 has a feature called PC Beep Bypass that allows system beeps to be heard even during system reset or BIOS boot-up.. Dock Interface The CRD05- is designed to dock with the CRD05- to simulate a notebook computer digital docking system. The CRD05- simulates the audio circuitry in the notebook computer and the CRD05- simulates the audio circuitry in the docking station. The CS05 serial ports provides the digital audio output for the digital docking station..5 Analog Outputs The LINE_OUT jack in figure 5 functions as the main stereo outputs in a two channel system. This circuit utilizes a Motorola MC07 dual opamp which is capable of driving high impedance line level signals (0 kω or greater). This circuit has a gain of db..6 S/PDIF Optical Output The S/PDIF (IEC-958) digital output in figure 6 is compatible with digital inputs on consumer devices such as stereo receivers and MiniDisc recorders. The S/PDIF output of the CS05 operates at a fix sampling frequency of 8 khz. The CRD05- S/PDIF digital optical output uses an industry standard Toshiba TOTX-7 optical transmitter..7 CNR Connector The CNR connector shown in figure 7 is the interface between the CRD05- and the system motherboard. The CNR interface supports audio, modem, and LAN subsystems. Also present on the CNR connector is Volt, 5 Volt, and. Volt power. The CRD05- uses the AC-Link, SM- Bus, Volt, and. Volt power. The SMBus signals are connected to a ATC0 EEPROM that enables plug-in-play functionality. The EEPROM holds the subsystem vendor ID and subsystem ID. It also contains other information for implementing a Plug-and-Play CNR card. See the Intel Communication and Network Riser homepage at for CNR design specifications, programming utilities, and information on programming the EEPROM. The CRD05- CNR connector includes jumpers for several functions. These are summarized in table.

NA ( pin jumper) Table. CNR Connector Jumper Settings Note:The CRD05- default positions for all jumpers is between pins - JP9 inserts a kω pull-up on Primary Down. This is used to disable on-board audio for motherboards that have a 0 kω pull-down resistor on Primary Down as required by the CNR. specification. In addition, JP and JP8 can be used to determine the clocking mode of the CS05. The CS05 supports three clocking modes: oscillator (Osc), crystal (Xtal), and AC-Link bit clock (BIT_CLK). This is shown in table. JP8 JP ID Osc PLL Frequency Mode Osc no.576 MHz Primary Osc yes.8 MHz Primary Osc yes MHz Primary Osc yes MHz Primary Xtal no.576 MHz Primary - - Bclk no.88 MHz Secondary - - Bclk no.88 MHz Secondary - - Bclk no.88 MHz Secondary Table. JP8 and JP Positions for Each Clock Mode The CS05 requires both digital. V and analog 5 V supply. The digital power is supplied from the CNR connector. A Motorola MC78M05C regulates the V supply from the CNR bus down to a clean 5 V analog supply. This 5 V linear regulator is used to maintain good audio quality..8 Component Selection Great attention was given to the particular components used on the CRD05- board with cost, performance, and package selection as the most important factors. Listed are some of the guidelines used in the selection of components: No components smaller than 0805 package. Only single package components passive components. No resistor packs. This reduces the risk of crosstalk between audio signals. All ICs are surface mount. Dual footprint for XTAL. Standard H9S and small circular CA-0 pin in hole package..9 EMC Components Optional capacitors and inductors are included to help the board meet EMI compliance tests, such as FCC Part 5. Choose these component values according to individual requirements.. GROUNDING AND LAYOUT One of the most critical aspects of PC audio design is good PC board layout. The PC is a hostile environment for audio and good layout is essential for achieving high audio quality. The CRD05- is partitioned into a digital and analog sections to help isolate noisy digital circuitry from quiet analog audio circuitry. The most important rule for successful PC audio layout is to keep all digital signal traces and components over the digital ground plane, and all analog signal traces and components over an analog ground plane. These planes are separated by a minimum of 60 to 00 mils (0.060 to 0.00 inches). Do not allow digital and analog signals to cross planes, otherwise digital noise may be induced into the analog signals and severely reduce audio performance. The CS05 is placed at the transition point of the analog and digital ground planes. The CS05 pins are partitioned into analog and digital areas. This is 5

6 CRD05- done to make board layout easier. The digital and analog grounds are tied together by a wide trace, over 50 mils or inches, at a single point underneath the CS05 in order to provide a common ground reference. Delta-sigma converters are highly susceptible to noise on the crystal pins. The area around the crystal oscillator and the two XTAL signals is filled with copper on the top and bottom sides and attached to digital ground. This ground plane serves to keep noise from coupling onto these pins. A separate chassis ground provides a reference plane for all of the EMC components. The chassis ground plane is connected to the analog ground plane at the external jacks. The capacitors on REFFLT, AFLT, AFLT, AFLT, and the power supply are placed close to the CS05 pins for best audio performance..
