3 KS999 emo oard User Guide.0 Introduction The KS999 demo board is designed to evaluate the performance of Micrel/Kendin 9- port integration switch with PHY and frame buffer. KS999 is configured as standalone switch with ports operating in 0Mbit/s or 00Mbit/s. ll of the ports are set up as auto negotiation as default. The KS999 demo board provides an industry standard MII (media independent Interface) to interface to external Processors for router and gateway applications. For dvanced set up such as QoS and VLN, please refer to the KS999 datasheet. This board is not intended for reference design or manufacturing.

5 KS999 emo oard User Guide 9-port SOHO switch is set up as default and port 9 is set to 00T & Full duplex as default. The data traffic can be connected through eight RJ connectors. ny of all 9 ports can be used as up link or down link. The 9 th port will be required external PHY for using as 9-port SOHO switch. In the case of Up- link port, there is no need of using a cross-over cable since the KS999 has auto MI/MIX cross-over feature.

MII and -wire Interface Setup Micrel-Kendin 9 ports 0/00 integrated switch with physical layer transceiver board you received is a multi functional board that can be configured for different interfaces. Port 9 can be configured as Forward MII, Reverse MII or -wire (SNI) interface. The default of this board is configured as ports switch. ll ports have been set up for auto-negotiation enabled mode. Note that the port 9 has only the M interface and there is no PHY. Since MII/SNI interfaces do not support auto-negotiation, the user needs to set up the Full/Half duplex and 0/00speed using the following jumpers. Micrel Kendin Page

11 KS999 emo oard User Guide U T0 9 U KS999_0 0 U,U MI90T Y Mhz.0 ES/P Reference Guideline ES and EMI (F) are basically the same problem for the system design. ES is absorbing energy and EMI is emitting energy. If your P board is good in EMI, it is also has good ES proof. ll high speed signal must has a unbroken reference ground plane. Minimum layer P is recommended, the layer stacking could be as following: layer component side (short traces) oz copper layer power plane oz copper layer GN plane oz copper layer signal mil trace /0 mil spacing oz copper layer signal mil trace /0 mil spacing oz copper layer GN signal oz copper ifferential pair is mil trace/mil spacing. So very few signal traces are exposed to outside, except the short traces from device pins to internal layers. It will improve ES, EMI and signal integrity. layer P is not recommended but if that is the only option, use the following layer stacking: layer component side oz copper mil layer GN plane oz copper layer power plane oz copper mil layer signal oz copper The thickness between layer and is mil, the thickness between layer and is mil. The following are the P layout guideline:. Keep Transmit differential pair on component side and Receive pairs on other layer, and route the differential pairs close together mil/mil space (parallel) and minimum 0 mil away from other signals.. Route lock traces directly above unbroken Ground plane and keep X trace width away from other signal traces. dd damping resistor ( to 0 OHM) at lock output.. Keep all signal traces inside the unbroken ground plane (in different layer).. The ground nets are all common.. Void power and ground planes directly under the magnetic. Micrel Kendin Page

12 KS999 emo oard User Guide. Use bulk capacitors uf to 00uf between power and ground plane on each corner of MIREL/KENIN chip.. Each power pin should have a 0.uf de-coupling cap close to the power pin, and drop via near the cap side.. roke the ground loop in certain location to avoid loop antenna effect. 9. Poorly regulated or over-burdened power supply will generate digital switching noise. Increase power traces width (0mil min.)or use copper pour whenever possible. minimum 0uF (0uF is recommended) capacitor should be used in the main outputs (.V,.V.0V etc). 0. dd damping resistors at all high speed digital signals and clock traces. The resistor should be located near the source side.. Metal case should be connected to chassis ground and at least 0 mil away from any signal traces. The chassis ground should be isolated from the rest of the circuitry.. Fill up the unused area on top and bottom side of the P with GN plane.. dd TVS transient suppression device at the I/O. The device is placed in parallel with the line to be protected. FERRITE E TO OUTSIE WORL V REF T? SR.
