Product Description

Available from 5.0 to 16.0MHz, the HCD220 features the superb performance of a HCD oven controlled oscillator within a sturdy chassis mountable package.

This OCXO comes with a wealth of extra features in addition to excellent quality output. There are two isolated RF outputs available for use on pins 4 and 5 respectively. Pin 7 can be configured to allow for an oven alarm, handy for testing and calibration uses, and when tight temperature control is required.

The HCD220 features excellent temperature stability options with stabilities as good as ±1ppb available. Exceptional aging characteristics are also possible as each product has been pre-aged before dispatch to ensure only the tiniest frequency fluctuations due to aging are present in the product you receive. The standard output waveform for this OCXO is sinewave, 7dBm into 50ohms but other options are available on request. Fast warm up is also available on request. Please enter your desired specification within your quotation.
