Texas Instruments LM2502
The LM2502 device is a dual link display interface SERDES that adapts existing CPU / video busses to a low power current-mode serial MPL link. The chipset may also be used for a RGB565 application with glue logic. The interconnect is reduced from 22 signals to only 3 active signals with the LM2502 chipset easing flex interconnect design, size and cost.| Part No. | LM2502 |

DESCRIPTION
The Master Serializer (SER) resides beside an application processor or baseband processor and translates a parallel bus from LVCMOS levels to serial MPL levels for transmission over a flex cable and PCB traces to the Slave Deserializer (DES) located near the display module. Dual display support is provided for a primary and sub display through the use of two ChipSelect signals. A Mode pin selects either a i80 or m68 style interface.
