40 MHz to 170 MHz 3rd overtone oscillator.

Contact for Sample Requests, Pricing, and Delivery

The CF7054H series crystal oscillator ICs operate with output frequencies spanning 40 MHz to 170 MHz 3rd overtone oscillation mode.

The oscillator circuit stage incorporates a stable voltage regulator which significantly reduces current consumption and fixes crystal drive current.

Excellent PSRR and frequency stability <<1ppm ΔF/ΔV result.

Three (3) pad layout package options enable wide range of ceramic LCC from 7.0x5.0 mm down to 1.6x1.2 mm. Operating temperature range is -40°C to 125°C
