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. Applicable Documents AES 3-1985 (ANSI S4.40-1985), AES 3-199XDraft, IEC 958, CP-340, EBU 3250 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.
