Raltron announced the VC8620D-D3-20-100.000-4-5, a low phase noise 100 MHz sine-wave voltage controlled crystal oscillator (VCXO) optimized for satellite payloads, ground stations, test and measurement and high performance synthesizer reference clock architectures. Delivering both excellent close-in phase noise and long-term stability, the new VCXO is ideal for LO, PLL, and clock distribution schemes where every decibel of noise and jitter directly impacts link budgets and system resolution.
The VC8620D-D3-20-100.000-4-5 provides a nominal 100.000 MHz output to drive mixers, PLL ICs and clock buffers without additional amplification. With low spurious levels of -80 dBc and no sub-harmonics, designers can maintain clean spectral masks in dense RF environments typical of satellite transponders and multi-band synthesizers.
Engineered as a precision reference, the VCXO is well-suited for long-life satellite ground infrastructure and mission-critical RF systems, helping maintain narrow channel spacing and stable LO plans over the life of the platform. The low-noise profile of the VC8620D-D3-20-100.000-4-5 supports low-jitter PLLs, high-order modulation schemes and high dynamic range receivers where phase noise directly impacts EVM and SNR.
Housed in a rugged 14.3 mm × 9.0 mm package with a maximum 5.6 mm height and gold-plated contacts on an FR5 board, the VCXO integrates smoothly onto dense RF boards, synthesizer modules and instrumentation backplanes.
“With this low phase noise 100 MHz VCXO, we set out to give our customers the spectral purity, stability and long-term reliability they need to unlock the full performance of their RF front ends and PLL architectures” said Sasha Wolloch, president of Raltron.
The VC8620D-D3-20-100.000-4-5 VCXO is available now for use in satellite communications equipment, RF synthesizers and other phase-noise-critical timing applications.
