CS9236

XTAL3I - 3 Volt Crystal Oscillator Input, PIN 6 (L), PIN 3 (Q).

This is the input pin for the on-chip crystal oscillator circuit. The CS9236 internal timing is

derived from one of two possible sources; the part may be supplied a 16.9344 MHz Master

Clock signal from an external source, or the timing may be generated using the on-chip

oscillator circuit in conjunction with an external 16.9344 MHz quartz crystal. When a Master

Clock signal is provided to the CS9236 from an external device, the Master Clock signal

should be connected to the CS9236 MCLK5I input pin and the XTAL3I input pin is grounded.

When the CS9236 internal timing is generated using the on-chip oscillator circuit, a 16.9344

MHz quartz crystal is connected between the CS9236 XTAL3I input pin and the XTALO

output pin, and the MCLK5I input pin is grounded. In this case, the XTALO output may be

used as a 384X master clock for the CS9236 digital audio output signal, SOUT.

XTALO - Crystal Oscillator Output/384X Digital Audio Clock Output, PIN 7 (L), PIN 4 (Q).

This pin is the output of the on-chip crystal oscillator circuit. This output may also be used as a

384X master clock for the CS9236 digital audio output signal, SOUT. The CS9236 internal

timing is derived from one of two possible sources; the part may be supplied a 16.9344 MHz

Master Clock signal from an external source, or the timing may be generated using the on-chip

oscillator circuit in conjunction with an external 16.9344 MHz quartz crystal. When a Master

VDD1, VDD2 - Digital Supply Voltage, PINS 21 and 9 (L), PINS 29 and 6 (Q), respectively.

3.3VDC supply voltage connections for the device.

GND1, GND2 - Digital Ground, PINS 22 and 8 (L), PINS 30 and 5 (Q), respectively.

0 VDC digital ground connections for the device.

NC - No Connection, PINS 1-4, 12-18, 25-28 (L), PINS 1, 9-26, 33-44 (Q)

These pins must be left floating (no connection to external circuitry).
