HD3-6408-9集成电路（IC）的编码器解码器转换器规格书PDF中文资料

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 (typically into a shift register). Finally, the parity bit is checked. If there were no Manchester or parity errors the Decoder responds with a valid word signal. The Decoder puts the Manchester code to full use to provide clock recovery and excellent noise immunity at these very high speeds.
