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 1 / 2 to 1 / 2 8 to give 64 possible clock speeds selectable at the users choice. 1 2 3 a b c d lk1 1 8 14 pin dip pin1 14 pin dip pin14 a b c d 1 2 3 lk1 8 pin dip u1 part number description PROG-MOD programmable oscillator module for more information contact :- r. f. solutions ltd., unit 21, cliffe industrial estate, south street, lewes, e. sussex. bn8 6jl. england. tel +44 (0)1273 898 000 fax +44 (0)1273 480 661 email sales@rfsolutions.co.uk internet http://w ww.rfsolutions.co.uk
