General DescriptionThe LM2502 deviceisa dual link display interface SERDES
that adapts existing CPU/ video bussestoa low power
current-mode serial MPL link. The chipset may alsobe used
fora RGB565 application with glue logic. The interconnectis
reduced from22 signalsto only3 active signals with the
LM2502 chipset easing flex interconnect design, size and
cost.
The Master Serializer (SER) resides besidean application
processoror baseband processor and translatesa parallel
bus from LVCMOS levelsto serial MPL levelsfor transmis-
sion overa flex cable and PCB tracesto the Slave Deseri-
alizer (DES) located nearthe display module.
Dual display supportis providedfora primary and sub
display throughthe useof two ChipSelect signals.A Mode
pin selects eitherai80or m68 style interface.
The Power_Down (PD*) input controlsthe power stateofthe
MPL interface. When PD*is asserted, the MD1/0 and MC
signals are powered downto save current.
The LM2502 implementsthe physical layerofthe MPL Stan-
dard (MPL-0). The LM2502is offeredin NOPB (Lead-free)
UFBGA and LLP packages.
