产品描述

The LM2512A is a MPL Serializer (SER) that performs a 24-bit to 18-bit Dither operation and serialization of the video signals to Mobile Pixel link (MPL) levels on only 3 or 4 active signals. An optional Look Up Table (Three X 256 X 8 bit RAM) is also provided for independent color correction. 18-bit Bufferless or partial buffer displays from QVGA (320 x 240) up to VGA (640 x 480) pixels can utilize a 24-bit video source.

The interconnect is reduced from 28 signals to only 3 or 4 active signals with the LM2512A and companion deserializer easing flex interconnect design, size constraints and cost.

The LM2512A SER resides by the application, graphics or baseband processor and translates the wide parallel video bus from LVCMOS levels to serial Mobile Pixel Link levels for transmission over a flex cable (or coax) and PCB traces to the DES located near or in the display module.

When in Power_Down, the SER is put to sleep and draws less than 10μA. The link can also be powered down by stopping the PCLK (DES dependant) or by the PD* input pins.

The LM2512A provides enhanced AC performance over the LM2512. It implements the physical layer of the MPL-1 and uses a single-ended current-mode transmission.
