PD63315
AC’97 SOUND CODEC
DESCRIPTION
The
µ
PD63315 is an audio codec compliant with the AC’97 Rev 2.1 specification. It features 18-bit ADC’s and
DAC’s (2 channels each) for mutual conversion between audio analog signals with a maximum signal band of 20 kHz
and digital signals, and supports full-duplex communication.
The analog signal input block has four analog stereo signal input lines, LINE, CD, VIDEO, and AUX, and three
analog monaural signal input lines, PHONE, PC_BEEP, and MIC (2 MIC pins selectable).
The analog signal output block has three outputs pins, LINE_OUT, LNLVL_OUT, and MONO_OUT, each with its
own volume control.
The
µ
PD63315 supports also sample rate conversion (SRC), EAPD, power management.
