LM2512A  
Mobile Pixel Link (MPL-1), 24-Bit RGB Display Interface  
Serializer with Optional Dithering and Look Up Table  
General Description  
Features  
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.  
24-bit RGB Interface support up to 640 x 480 VGA format

Optional 24 to 18-bit Dithering  
Optional Look Up Table for independent color correction  
MPL-1 Physical Layer  
SPI Interface for Look Up Table control and loading  
Low Power Consumption & Powerdown state  
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.  
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.  
Dithered Data Reduction

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.  
Small Interface, Low Power and Low EMI  
Intrinsic Level Translation
