Digital Outputs

XTO - Crystal Oscillator Output, PIN 15.

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.

ACKO - Analog Clock Output, PIN 22.

This output is 128

× the input word rate (LRCK frequency). Normally connected to the Analog

Clock Input pin, ACKI.

CALO - Calibration Output, PIN 21.

Used during offset calibration. Must be connected to the Calibration Input pin, CALI.

CMPO - Comparator Output, PIN 6.

Used during offset calibration. Must be connected to the Comparator Input pin, CMPI.

Miscellaneous

NC - No Connection, PINS 7, 23.

These two pins are bonded out to test outputs. They must not be connected to any external

component or any length of PC trace.

TST -Test Input, PIN 10.

Allows access to the CS4328 test modes, which are reserved for factory use. Must be tied to

DGND.
