In such systems, These transformers are recommended for use with the two channels of periodically sampled and uniformly Cirrus Logic CS8401, CS8402, CS8403 and CS8404 quantized audio signals are transmitted on a single shielded Digital Audio Interface Transmit Device. twisted pair. The schematic below represents an implementation of The electrical parameters of the interface are based on transmit and receive circuits using isolation transformers at those of CCITT V.II or balanced voltage digital circuits which both ends. Equalization in the receiver may permit to allow signal transmission up to a few hundred meters. increase the length of the interconnecting cable.
