LM4308 - Texas Instruments

LM4308 Mobile Pixel Link Two (MPL-2) - 18-bit CPU Display Interface Master/Slave

The LM4308 device adapts a 18-bit CPU style display interfaces to a MPL-2 SLVS differential serial link for displays. Two chip selects support a main and sub display up to and beyond 640 x 480 pixels. A mode pin configures the device as a Master (MST) or Slave (SLV). Both WRITE and READ operations are supported. CPU interface widths below 18-bits are support.
