LM2512A www.ti.com 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 1 2 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 Level Translation Between Host and Display Optional Auto Power Down on STOP PCLK Frame Sequence Bits Auto Resync upon Data or Clock Error 1.6V to 2.0V Core / Analog Supply Voltage 1.6V to 3.0V I/O Supply Voltage Range SYSTEM BENEFITS Dithered Data Reduction Independent RGB Color Correction 24-bit Color Input Small Interface, Low Power and Low EMI Intrinsic Level Translation 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 24bit 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 cos...
