Voltage Controlled Crystal Oscillators
981VH M 982VH
Monitor Products’ 981VH and 982VH VCXOs are TTL/HCMOS compatible and are manufac-
tured using the latest hybrid technology. Hermetically-sealed packages offer excellent
resistance to environmental extremes, including shielding to minimize RF radiation.
Monitor Products has a
proven track record as a
pioneer manufacturer in
the frequency control
market. If our extensive
selection of standard and
engineered crystals and
oscillators does not meet
your spec, we will work
with you towards a
customized solution.
