CMOS Asynchronous Serial

Manchester Adapter (ASMA)

March 1997

Features

Description

• Low Bit Error Rate

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

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 immu-

nity at these very high speeds.

• Sync Identiﬁcation and Lock-In

• Clock Recovery

• Manchester II Encoder, Decoder

• Separate Encode and Decode

• Low Operating Power . . . . . . . . . . . . . . . . . 50mW at 5V

• Single Power Supply

• 24 Lead Package

The HD-6408 can be used in many commercial applications

such as security systems, environmental control systems,

serial data links and many others. It utilizes a single 12 x

clock and achieves data rates of up to one million bits per

second with a very minimum overhead of only 4 bits out of

20, leaving 16 bits for data.
