RVG1490L Datasheet, PDF (1/2 Pages) TEMEX – GHZ AND ULTRA-LOW JITTER

GHZ AND ULTRA-LOW JITTER | PERFORMANCE VCXO
RVG1490L
This high performance VCXO delivers frequencies up to 2.2 GHz with ultra-low RMS phase jitter (as low as 15 fs typ, 12kHz-20MHz).
RVG1490L is an ideal solution for Optical Coherent Networking, and high speed ADC/DAC/SERDES clocking, where excellent oscillator phase
noise and jitter is critical to system performance. This product is also available as a XO, Rakon RXG1490L.
Features
 Frequency range from 1 GHz up
to 2.2 GHz
 Ultra-low RMS phase jitter
 Sinewave, Differential Sinewave or LVPECL
 Lower temperature sensitivity than SAW
Applications
 Coherent Optical Modules
 Base Station Remote Radiohead
