Ultra-Low Noise VCXO
Improves Jitter Generation
Thu, 04/28/2016 - 9:32am by Crystek
Crystek continues to push the limits of Ultra-Low Phase
Noise performance with the release of the CVPD-922
Family. This Voltage Controlled LVPECL Oscillator
outperforms other LVPECL phase noise oscillators. Close-in
phase noise has been reduced to -85dBc/Hz @ 10 Hz
offset while the noise floor is at -162 dBc/Hz. Available in
a frequency range from 40 MHz to 125 MHz.
Engineered and manufactured in the USA, the model
CVPD-922 is packaged in the industry-standard 9x14 mm
SMD package. Input supply voltage is +3.3 V, with a max.
current consumption of 88 mA.
Users will see an immediate improvement in jitter
generation by replacing the legacy LVPECL oscillator (-145
dBc/Hz floor) with Crystek’s new CVPD-922 family. Crystek
also offers a CLOCK version – the CCPD-575 family in a
5x7.5 mm package.
SAW Oscillators Tolerate ±150 ppm
