VT1616 6-Channel AC97 Codec with S/PDIF
PCM Front and Center DAC Sample Rate Register (Index 2Ch)
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Default
SR15 SR14 SR13 SR12 SR11 SR10 SR9 SR8 SR7 SR6 SR5 SR4 SR3 SR2 SR1 SR0 BB80h
SR[15:0]
Main stereo + Center or all DAC Sample Rate (in Hz)
16-bit unsigned value representing the sample rate in 1Hz resolution. The default value is 48 KHz
(48000 = BB80h). This register controls all six DAC output rate providing a sample accurate
synchronization among the channels. Registers 2Eh and 30h are read/writable but have no control
over the Surround and LFE channels. They reflect 2Ch when read back.
PCM Surround DAC Sample Rate Register (Index 2Eh)
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Default
SR15 SR14 SR13 SR12 SR11 SR10 SR9 SR8 SR7 SR6 SR5 SR4 SR3 SR2 SR1 SR0 BB80h
SR[15:0]
Surround DAC Sample Rate (in Hz)
16-bit unsigned alias value of 2Ch representing the sample rate in 1Hz resolution. The default value
is 48 KHz (48000 = BB80h). This register has no physical control over the Surround pair DACs
sampling rate.
PCM LFE DAC Sample Rate Register (Index 30h)
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Default
SR15 SR14 SR13 SR12 SR11 SR10 SR9 SR8 SR7 SR6 SR5 SR4 SR3 SR2 SR1 SR0 BB80h
SR[15:0]
LFE DAC Sample Rate (in Hz)
16-bit unsigned alias value of 2Ch representing the sample rate in 1Hz resolution. The default value
is 48 KHz (48000 = BB80h). This register has no physical control over the LFE DAC’s sampling
rate.
PCM ADC Sample Rate Register (Index 32h)
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Default
SR15 SR14 SR13 SR12 SR11 SR10 SR9 SR8 SR7 SR6 SR5 SR4 SR3 SR2 SR1 SR0 BB80h
SR[15:0]
ADC Sample Rate (in Hz)
16-bit unsigned value representing the sample rate in 1Hz resolution. The default value is 48 KHz
(48000 = BB80h).
