Bliley’s NV45AD1725 oven-controlled voltage-controlled crystal oscillator (OCVCXO) features super-low phase noise as well as a low-G sensitivity. It’s a good choice for microwave frequency systems that are subject to vibration and environmental effects. It also can be used in critical radar, navigation, and communications equipment.

The Bliley NV45AD1725 is an OCVCXO with a 100-MHz sine output. It has a low phase noise specification of –170 dBc/Hz at 100-kHz offset. Frequency stability is ±50 ppb, and G-sensitivity is 5 x 10–10 G/axis.

This 100-MHz sinewave device is designed to be used in phase-locked signal sources like dielectric resonator oscillators (DROs). Its basic stability is ±50 ppb from 0°C to 50°C. Typical output power ranges from 12 to 15 dBm. Harmonics are down –30 dBc, and spurious emissions are down –80 dBc. Phase noise is –170 dBc/Hz at 100-kHz offset. Different versions are available.

The oscillator measures 1 by 1 by 0.46 in. Two versions are available to operate from 12 or 15 V dc (see the figure). Steady-state power consumption is 1 W at 25°C. G-sensitivity with a sine vibration is 5 x 10–10 G/axis.

Designed for portable devices, the NVG79 OCXO offers a 20-kHz to 54-MHz frequency range and ±0.025-ppm frequency stability from 0°C to 60°C.

Also, the NVG79 oven-controlled crystal oscillator (OCXO) targets handheld radios, handset-based mobile resource and field asset management systems, mobile basestations, and other communications systems in the telecom, utility, industrial, and military sectors. It comes in a frequency range from 20 kHz to 54 MHz. Standard or custom frequencies are available. Frequency stability is ±0.025 ppm from 0°C to 60°C. Both sine and HCMOS compatible outputs are available.
