AHA3431 - AHA

AHA3431 SIMULTANEOUS COMPRESSOR/DECOMPRESSOR IC

The coprocessor device has three external high speed synchronous data ports each capable of transferring once every clock. These are a 32-bit bidirectional data port, an 8-bit Video Input Data (VID) port and a Video Output Data (VOD) port. The data port is capable of transferring up to 32 bits per clock. The VID and VOD are also capable of one transfer per c.
