Oscillators provide frequency stabilities
in the range of ±± ppb to ±±0 ppb, over
the commercial, extended commercial or
the industrial temperature range. Power
requirements are 1.1W over the commercial
temperature range and 1.±W over the
industrial temperature range after warm-up.
Additionally, excellent aging is achieved
through the use of overtone SC cut crystals.
The OH300 series is available with CMOS
logic or Sinewave output along with Voltage
Controlled option. These oscillators provide
outstanding phase noise that varies depending
on frequency requirements. Allan Variance
specifications are rated for primary reference
standards. Warm up times are on the order of
± minutes to 0.10 ppm of final frequency.
