TRANSFORMERS FOR DIGITAL
AUDIO DATA TRANSMISSION
For Use with Cirrus Logic’s CS8401,
CS8402, CS8403 & CS8404 ICs
These transformers have been designed for use at the
interface between line driver and receiver and the intercon-
necting medium in Digital Audio Data Transmission Systems
according to AES 3-199X or IEC 958. In such systems,
two channels of periodically sampled and uniformly
quantized audio signals are transmitted on a single shielded
twisted pair.
The electrical parameters of the interface are based on
those of CCITT V.II or balanced voltage digital circuits which
allow signal transmission up to a few hundred meters.
The isolation transformers are essential in improving the
balance of the transmitter and the receiver circuitry, and
reducing common mode noise and EMI.
These transformers are recommended for use with the
Cirrus Logic CS8401, CS8402, CS8403 and CS8404
“Digital Audio Interface Transmit Device.”
The schematic below represents an implementation of
transmit and receive circuits using isolation transformers at
both ends. Equalization in the receiver may permit to
increase the length of the interconnecting cable.
