| ICEPIC PROG-MOD OSCILLATOR * * * * * * Frequency Range 46.875kHz-24.00MHz Low current consumption (CMOS IC structure) Starting time < 1.5mS High noise immunity No adjustment needed once frequency selected Frequency accurate to 100 ppm The PROG-MOD uses a super small CMOS crystal clock oscillator and fits in a 14 pin DIP package equipped with a programmable frequency divider. 7 different oscillators are 1 1 8 supplied and each frequency can be divided by / 2 to / 2 to give 64 possible clock speeds selectable at the users choice.

Changing The Crystal IC To ensure proper operation of the PROG-MOD oscillator the crystal IC must be inserted in the correct position. Pin 1 of the crystal IC must be inserted into the Pin 1 position of the 14 pin DIP package marked with a yellow triangle and make sure all pins are properly fitted into the 8 pin socket.
