CS5211
Datasheet
1 Introduction
The CS5211 is an eDP to LVDS converter with flexible configuration for the low-cost display system. CS5211 is
compliant with eDP 1.2 and supports 1 lane and 2 lanes mode at 1.62Gbps and 2.7Gbps per lane speed. With
powerful SerDes technology, CS5211 can recover high-speed serial data with a low bit error rate.
CS5211 LVDS transmitter supports single port and two ports mode. The maximum resolution supported by
CS5211 is WUXGA (1920x1200). With 4 configuration pins, CS5211 can support 16 combinations for different
panel resolution and LVDS working mode with one EEPROM image. A convenient tool is also provided to edit,
generate and update EEPROM image for customized configuration.
With optimized design, the usage of CS5211 is apt to save the BoM cost. The clock source is integrated into this
chip, so the external crystal can be saved; with wide range power supporting (1.8 ~ 1.2V for core power), power
device on board could be saved; the total power of CS5211 is less than 300mW, so the power supply network
design could be simplified. It is easy to integrate the CS5211 to a popular low-cost display system.
