When a crystal oscillator is used, it is tied between this pin and XTI. When an external clock is
input, this pin should be left floating.
This output is 128 the input word rate (LRCK frequency). Normally connected to the Analog
Clock Input pin, ACKI.
Used during offset calibration. Must be connected to the Calibration Input pin, CALI.
Used during offset calibration. Must be connected to the Comparator Input pin, CMPI.
These two pins are bonded out to test outputs. They must not be connected to any external
component or any length of PC trace.
Allows access to the CS4328 test modes, which are reserved for factory use. Must be tied to
DGND.
