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.
