100 MHz VCXO targets low-noise RF timing

Raltron has announced the VC8620D-D3-20-100.000-4-5, a 100 MHz sine-wave voltage-controlled crystal oscillator in a 14.3 × 9.0 × 5.6 mm package for satellite payloads, ground stations, test and measurement equipment and RF synthesizer reference clocks. The device provides a nominal 100.000 MHz output for mixers, PLL ICs and clock buffers, with spurious levels of -80 dBc and no sub-harmonics to support cleaner spectral masks in dense RF environments. The VCXO is intended for LO, PLL and clock distribution designs where phase noise and jitter affect EVM, SNR and channel spacing. It is designed for dense RF boards, synthesizer modules and instrumentation backplanes with gold-plated contacts on an FR5 board.
