Quantity / Special Request

Please specify the quantity you require below.

The HCD280 is supplied in boxes. 10 pcs per box is the maximum box size for this product.

Product Description

The HCD280 oven controlled oscillator provides excellent stability and phase noise characteristics, at frequencies from 30.0 ~ 100MHz and conforms to MIL-STD-202 standards for shock, vibration and humidity specifications.

This OCXO boasts three different phase noise profiles (A, B, and C), including superb close-in phase noise of -105 dBc/Hz @ 10Hz, and excellent phase noise floor of -170 dBc/Hz @ 10kHz (profile C).

This OCXO also provides excellent overall stability, with temperature stability options as good as ±10ppb, and frequency stability of <500ppb per year. A choice of ageing characteristics is also available, with options down to <±1x10-9 per day. Frequency adjustment sufficient for 10 years ageing minimum also comes as standard.

Several supply voltage options are available, including 3.3V, 5.5V and 12.0V, along with the choice of sine output (+9dBm ±1dBm into 50Ω AC coupled) or CMOS (10kΩ//15pF 45:55 Max).
