SNLS269B –AUGUST 2007–REVISED MAY 2013  
LM2512A Mobile Pixel Link (MPL-1), 24-Bit RGB Display Interface Serializer with Optional  
Dithering and Look Up Table  
Check for Samples: LM2512A

FEATURES  
DESCRIPTION  
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.

•
MPL-1 Physical Layer  
SPI Interface for Look Up Table Control and  
Loading  
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.

Low Power Consumption & Powerdown State  
Level Translation Between Host and Display  
Optional Auto Power Down on STOP PCLK  
Frame Sequence Bits Auto Resync upon Data  
or Clock Error  
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.

•
1.6V to 2.0V Core / Analog Supply Voltage  
1.6V to 3.0V I/O Supply Voltage Range  
SYSTEM BENEFITS  
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.

Independent RGB Color Correction  
24-bit Color Input  
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.
