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 mem-
ory, 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 valid-
ity data directly from serial input pins with dedicated
• ^{Configurable Buffer Memory (CS8401A) input pins for the most important channel status bits.}
• Transparent Mode Allows Direct
Connection of CS8402A and CS8412
or CS8401A and CS8411A
