Left Channel Filter. Requires a 1.0 F to analog ground for proper
operation.
Right Channel Filter. Requires a 1.0 F to analog ground for proper
operation.
Left Channel Antialias Filter. This pin requires a 560 pF NPO
capacitor to analog ground for proper operation.
Right Channel Antialias Filter. This pin requires a 560 pF NPO
capacitor to analog ground for proper operation.
Description
33 MHz Crystal Output. If no Crystal is present leave XTALO
unconnected.
33 MHz Clock. When using a crystal as a clock source, the crystal should
be connected between the XTALI and XTALO pins. Clock input may
be driven into XTALI in place of a crystal. When using an external clock,
