Programmable Baud Rate Generator
5- to 9-bit full-duplex synchronous or asynchronous serial communications
RS485 with driver control signal
ISO7816, T = 0 or T = 1 Protocols for interfacing with smart cards
IrDA modulation and demodulation
Test Modes 46
Provides serial synchronous communication links used in audio and telecom applications (with
CODECs in Master or Slave Modes, I2S, TDM Buses, Magnetic Card Reader, etc.)
Contains an independent receiver and transmitter and a common clock divider
Offers a configurable frame sync and data length
Receiver and transmitter can be programmed to start automatically or on detection of different
event on the frame sync signal
Receiver and transmitter include a data signal, a clock signal and a frame synchronization signal
Compatible with AC97 Component Specification V2.2
Capable to Interface with a Single Analog Front end
Three independent RX Channels and three independent TX Channels
Time Slot Assigner allowing to assign up to 12 time slots to a channel
Channels support mono or stereo up to 20 bit sample length - Variable sampling rate AC97 Codec
Interface (48KHz and below)
