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.

Frequency Divider Selection Links

The frequency required is selected by means of

links LK1 located on the module.

PROG-MOD Standard Frequencies

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

2

8

to give 64 possible clock speeds selectable at the users

choice.
