Serial Synchronous Controller
⢠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
AC97 Controller
⢠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
â One RX and one TX channel dedicated to the AC97 Analog Front end control
â One RX and one TX channel for data transfers, connected to the DMACA
â One RX and one TX channel for data transfers, connected to the DMACA
⢠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)
