NAME
FUNCTION
1
GNDA
Ground for DAC
2
VREF
Voltage Reference Output. This pin must be decoupled with a 100μF ceramic capacitor to ground.
3
VCC
Power Supply for Digital Control and Temperature Sensor. This pin must be decoupled with a
100nF capacitor to ground.
4
VOSC
Power Supply for Oscillator Circuit. This pin must be decoupled with a 0.1μF capacitor to ground.
5
GNDOSC
Ground for Oscillator Circuit
6–10
N.C.
No Connection. Must be connected to ground.
11
GND
Ground for Digital Control, Temperature Sensor, and Controller Substrate
12
SDA
Serial Data Input/Output. SDA is the data input/output for the I2C interface. This open-drain pin
requires an external pullup resistor.
13
SCL
Serial Clock Input. SCL is the clock input for the I2C Interface and is used to synchronize data
movement on the serial interface.
14
GNDD
Ground for Oscillator Output Driver
15
FOUT
Frequency Output, CMOS Push-Pull
16
VCCD
Power Supply for Oscillator Output Driver. This pin must be decoupled with a 0.1μF capacitor to
ground. A 20
resistor must be placed in series between the power supply and VCCD.
