Name

Description

No connect. The NC pin can be connected to VCC, GND or left floating.

SCL

Serial clock input

FOUT

Programmable frequency output (CMOS). The FOUT pin is Hi-Z if FOE is low.

No function. The NF pin can be connected to VCC, GND or left floating.

Do not use externally. The DU pin must be left floating.

6VCC

Power supply

FOE

Frequency output enable, controls the frequency output on FOUT pin

No connect. The NC pin can be connected to VCC, GND or left floating.

No function. The NF pin can be connected to VCC, GND or left floating.

IRQ

Interrupt output (open drain)

VSS

Ground supply

No function. The NF pin can be connected to VCC, GND or left floating.

SDA

Serial data input/output

No connect. The NC pin can be connected to VCC, GND or left floating.
