Low Phase Noise CMOS Oscillator offers -168 dBc/Hz noise floor.
August 24, 2011 -
Supplied in 5 x 7.5 mm package, U.S.-manufactured CCHD-575 clock oscillator generates frequencies from 50-130 MHz and has typ phase jitter of 82 fsec RMS at 100 MHz. Close-in phase noise is -90 dBc/Hz @ 10 Hz, while floor is at -168 dBc/Hz. Output driver can drive ±24 mA, translating to rise/fall time of ~600 psec at 100 MHz with 15 pF load. Available with extended operating range of -40 to +85°C, product accommodates 3.3 Vdc supply and consumes 15 mA current.

New Ultra-Low Phase Noise CMOS Oscillator from Crystek Provides -168 dBc/Hz Noise Floor
Fort Myers, FL - Crystek Corporation has launched the CCHD-575, a new Ultra-Low Phase Noise CMOS Oscillator providing a -168 dBc/Hz noise floor. Compact and powerful, the CCHD-575 is the industry's lowest-jitter clock oscillator in a 5 x 7.5 mm package.
Crystek's CCHD-575 features a typical phase jitter of 82 fSec RMS at 100 MHz. Close-in phase noise is -90 dBc/Hz @ 10 Hz, while its floor is at -168 dBc/Hz. The extremely low phase noise performance is very useful in applications such as: DACs (digital-to-analog converters), ADCs (analog-to-digital converters), low phase signal sources, and test & measurement.
The CCHD-575 generates frequencies between 50MHz and 130MHz. Its output driver is capable of driving ±24mA, translating to a rise/fall time of ~600ps at 100 MHz with a 15pF load. Input supply voltage of 3.3Vdc consuming 15mA of current is required. Extended temperature operating range of -40°C to +85°C is also available.
The Crystek CCHD-575 CMOS Oscillator is made in the U.S.A. and available from Crystek's stocking distributors. For pricing details, contact Crystek Corporation.
