OUTLINE & DIMENSIONS
DESCRIPTION
XO7050 oscillators utilise AT-Cut crystals providing much improved,
tight frequency stability as opposed to that stabiity provided by
32.768kHz oscillators using the more usual X-Cut (tuning fork)
crystals. The tight control of frequency provided by these oscillators
results in a typical variation of 52 seconds for one month of
continuous operation as against 260 seconds over the same period
for oscillators that use tuning fork crystals.Other benefits include low
supply current consumption coupled with quick start-up times.
