DATASHEET HD-6408 CMOS Asynchronous Serial Manchester Adapter (ASMA) FN2952 Rev 3.00 October 1, 2015 The HD-6408 is a CMOS/LSI Manchester Encoder/Decoder for creating a very high speed asynchronous serial data bus.
The Encoder converts serial NRZ data (typically from a shift register) to Manchester II encoded data, adding a sync pulse and parity bit.
The Decoder recognizes this sync pulse and identifies it as a Command Sync or a Data Sync.
The data is then decoded and shifted out in NRZ code
