Product Description

The HCD380 oven controlled oscillator with sine wave output is available up to very high frequency of 100MHz with very low phase noise.

The internal oscillator within the HCD380 has been specifically designed not to include multiplication, ensuring ultra-low phase noise performance down to -160dBc/Hz @10kHz, even at very high frequencies.

This OCXO also features excellent temperature stability, good frequency adjustment (covering 10 years ageing minimum), and offers a choice of supply voltages and operating temperature ranges.
