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 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.

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 Standard (MPL-0). The LM2502 is offered in

NOPB (Lead-free) NFBGA and WQFN packages.
