The G326 series voltage-controlled oscillators (VCXOs) use fundamental mode crystals for superior phase-noise performance. Available in frequencies from 1 to 50 MHz, the VCXOs feature integrated phase jitter of 200fs (typical) and suit a wide range of timing applications, such as phase lock loops (PLL), SONET, ATM, set-top boxes, MPEG, audio-video modulation, video game consoles and HDTV, ONET, 10GbE, Fiber Channel, wireless repeaters, transponders, FPGAs, and data acquisition. Unlike standard clock oscillators that have a fixed output frequency, the output of G326 VCXOs can be tuned 50 to 200 ppm up or down from the nominal frequency by varying a control voltage accessed via a pad on the component. This control voltage operates on a varactor. Housed in a low mass, ultra-miniature 6-pad SMD package measuring 3.2 mm x 2.5mm x 1 mm, the G326 series is available in 1.8, 2.5, 3.3 or 5-Vdc supply voltage versions and offer CMOS (15pF) or TTL (two gates) output. Additional specifications include rise/fall times of 6ns maximum, duty cycle of 50% ±10% (±5% available to order), start-up time within 10ms, current consumption of 10 to 45mA dependent on frequency, and linearity of 6% typical, 10% maximum.
