AC’97 Controller
Pulse Width Modulator Controller
The ConnectCore XP 270 AC’97 controller supports the “Audio Codec ’97 Component
Specification, Revision 2.0”. The AC-link is a synchronous, fixed-rate serial bus
interface to the digital AC’97 controller for transferring digital audio, modem,
microphone input (MIC-in), Codec register control, and status information.
Features
The AC’97 controller does not support the following optional AC’97 Revision 2.0
features:
ConnectCore XP 270 provides two PWM outputs. Each PWM operates independently of
the other. In general, the PWM controller provides a basic digital-to-analog converter
with an appropriate analog filter; for example, controlling the brightness of an LED
output or controlling LCD contrast.
Independent channels for stereo pulse code modulation (PCM) in, stereo
PCM out, modem out, modem-in, and mono MIC-in. All of the channels
support only 16-bit samples in hardware. Samples less than 16 bits are
supported through software.
Multiple sample rate AC’97 2.0 Codecs (48 kHz and below). The AC’97
controller depends on the Codec to control the varying rate.
Secondary Codec support
Three receive FIFOs (32-bit, 16 entries)
Two transmit FIFOs (32-bit, 16 entries)
Optional AC97_SYSCLK output (support for Codecs without oscillators or
crystals)
Double-rate sampling (n+1 sample for PCM L, R and C)
18- and 20-bit sample lengths
