HD-6408 Data Sheet October 1, 2015 FN2952.3 CMOS Asynchronous Serial Manchester Features Adapter (ASMA) Low Bit Error Rate The HD-6408 is a CMOS/LSI Manchester Encoder/Decoder Data Rate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1MBit/s for creating a very high speed asynchronous serial data bus. Sync Identification and Lock-In The Encoder converts serial NRZ data (typically from a shift register) to Manchester II encoded data, adding a sync pulse Clock Recovery and parity bit. The Decoder recognizes this sync pulse and Manchester II Encoder, Decoder identifies it as a Command Sync or a Data Sync. The data is then decoded and shifted out in NRZ code (typically into a Separate Encode and Decode shift register). Finally, the parity bit is checked. If there were Low Operating Power. . . . . . . . . . . . . . . . . . . 50mW at 5V no Manchester or parity errors the Decoder responds with a valid word signal. The Decoder puts the Manchester code to Single Power Supply full use to provide clock recovery and excellent noise 24 Ld Package immunity at these very high speeds. Pb-Free Plus Anneal Available (RoHS Compliant) The HD-6408 can be used in many commercial applications such as security systems, environmental control systems, Ordering Information serial data links and many others. It utilizes a single 12 x TEMP. clock and achieves data rates of up to one million bits per PART PART RANGE PKG. second with a very minimum overhead of only 4 bits out of NUMBER MARKING (C) PACKAGE NO. 20, leaving 16 bits for data.
