oversampling ratio, normal HPF mode, and not in power-down mode. For more information on the operating
modes and clock timing of the PCM1802 and PCM1803A device, see the
PCM1802 Single-Ended Analog-Input
24-Bit, 96-kHz Stereo A/D Converter and PCM1803A Single-Ended, Analog-Input 24-Bit, 96-kHz Stereo A/D
Converter data sheets , respectively.
In addition, the SCKI signal can be sourced from an onboard oscillator or provided externally at J9. J4 selects
the SCKI clock source (SCK_OSC) or externally from J9 (SCK_IN) by changing the position of J4 as shown in
Table 4-7 .
