3 Section 1 Introduction 1.1 Overview The EP103 LVDS transmitter supports transmission between the host and the flat panel display up to SXGA+ resolutions. The transmitter converts 32 bits (10-bits/color, 2 dummy bits) of CMOS/TTL data and 3 control bits into 5 LVDS (Low Voltage Differential Signal) data streams. At a maximum input clock rate of 135MHz, each LVDS differential data pair speed is 945Mbps, providing a total throughput of 4.7Gbps. The transmitter can be configured to input clock rising edge or falling edge strobe through an external pin. 1.2 Features The EP103 includes the following distinctive features: Support 8MHz to 135MHz clock rates for NTSC to SXGA+ resolution Up to 4.7Gbps bandwidth PLL requires no external components Cycle-to-cycle jitter rejection Programmable data and control strobe select Reduced swing LVDS supported Power down mode supported Compatible with THine THC63LVD103 Single 3.3V CMOS design 64-pin LQFP (Pb Free, compliant to JEDEC/IPC J-STD-006) 3

14 2.6 LVDS Outputs / TTL Data Inputs Mapping The LVDS Clock waveshape is shown in the following figure. Note that the rising edge of the LVDS clock occurs two LVDS sub symbols before the current cycle of data. The clock is composed of a 4 LVDS sub symbol HIGH time and a 3 LVDS sub symbol LOW time. The respective pin names are shown in the figure and these names are not the color mapping information but pin names only.
