TRANSFORMERS FOR DIGITAL AUDIO
DATA TRANSMISSION
For Use with Cirrus Logic’s CS8401,
CS8402, CS8403 & CS8404 ICs
Electronics
Application
These transformers have been designed for use at the
interface between line driver and receiver and the interconnecting medium in Digital Audio
Data Transmission Systems according to AES 3-199X or IEC 958. In such systems, two chan-
nels 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 volt-
age 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.
