6438F–ATARM–21-Jun-10
Description
Embedded Characteristics
The AC97 Controller is the hardware implementation of the AC97 digital controller (DC’97) com-
pliant with AC97 Component Specification 2.2. The AC97 Controller communicates with an
audio codec (AC97) or a modem codec (MC’97) via the AC-link digital serial interface. All digital
audio, modem and handset data streams, as well as control (command/status) informations are
transferred in accordance to the AC-link protocol.
The AC97 Controller features a Peripheral DMA Controller (PDC) for audio streaming transfers.
It also supports variable sampling rate and four Pulse Code Modulation (PCM) sample resolu-
tions of 10, 16, 18 and 20 bits.
• 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
– One RX and one TX channel dedicated to the AC97 Analog Front end control
– One RX and one TX channel for data transfers, associated with a PDC
– One RX and one TX channel for data transfers with no PDC
– Variable sampling rate AC97 Codec Interface (48KHz and below)
