LM2502

www.DataSheet4U.com August 2005 LM2502 Mobile Pixel Link (MPL) Display Interface Serializer and Deserializer 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 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) UFBGA and LLP packages.
