LM2502

Mobile Pixel Link (MPL) Display Interface Serializer and

Deserializer

General Description

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.

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 transmis-

sion over a flex cable and PCB traces to the Slave Deseri-

alizer (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.

The Power_Down (PD*) input controls the power state of the

MPL interface. When PD* is asserted, the MD1/0 and MC

signals are powered down to save current.

The LM2502 implements the physical layer of the MPL Stan-

dard (MPL-0). The LM2502 is offered in NOPB (Lead-free)

UFBGA and LLP packages.
