Digital Audio Interface Transmitter
Features
General Description
• Monolithic Digital Audio Interface
The CS8401/2A are monolithic CMOS devices which encode and transmit audio data according to the
Transmitter
AES/EBU, IEC 958, S/PDIF, & EIAJ CP-340 interface
• Supports: AES/EBU, IEC 958, S/PDIF, & EIAJ CP-340
standards. The CS8401/2A accept audio and digital data, which is then multiplexed, encoded and driven onto a cable. The audio serial port is double buffered
Professional and Consumer Formats and capable of supporting a wide variety of formats.
• Host Mode and Stand Alone Modes • Generates CRC Codes and Parity Bits
The CS8401A has a configurable internal buffer memory, loaded via a parallel port, which may be used to buffer channel status, auxiliary data, and/or user data.
• On-Chip RS422 Line Driver
The CS8402A multiplexes the channel, user, and validity data directly from serial input pins with dedicated
• Con.
