Pin Description
PIN
NAME
FUNCTION
1
OUT
Oscillator Output
2
SPRD
Dither Enable. When the pin is high, the dither is enabled. When the pin is low, the dither is disabled.
3VCC
Power Supply
4
GND
Ground
5OE
Output Enable. When the pin is high, the output buffer is enabled. When the pin is low, the output is disabled
but the internal master oscillator is still on.
6
PDN
Power-Down. When the pin is high, the master oscillator is enabled. When the pin is low, the master oscillator
and the output buffer are disabled (power-down mode).
7
SDA
I
2C Serial Data. This pin is for serial data transfer to and from the device.
8
SCL
I
2C Serial Clock. This pin is used to clock data into and out of the device.
