PROG-MOD Datasheet, PDF (1/1 Pages) rfsolutions.ltd – Programmable Oscillator Module

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
supplied and each frequency can be divided by ¹ / 2
to
1
/
8
2
to give 64 possible clock speeds selectable at the users
choice.

PROG-MOD Package Contents
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.
WARNING
The crystal oscillator employs a CMOS IC integrated with
a protection circuit for static electricity, please handle only
in an anti-static environment.
