VCSO delivers expanded frequency range, ultra-low jitter

Hudson, N.H. — Vectron International has released the fifth generation of its voltage-controlled SAW oscillators (VCSOs). The VS-705 VCSO delivers new and improved features including an expanded frequency range and power management capabilities that support “green” initiatives.

TheVS-705 offers an expanded frequency range of 120 MHz to 850 MHz in a 5.0 x 7.5 x 2.5-mm LCC package. Previously, frequencies between 120 MHz to 500 MHz were only offered in a 9.0 x 14.0 x 4.5-mm package and frequencies between 500 MHz to 850 MHz were supported in a 5.0 x 7.5 x 2.5-mm LCC package.

The VCSO is optimized for use in phase-locked loop (PLL) circuits that require excellent jitter filtering and a wider tuning range (+/-100 ppm APR). Applications include high-speed data transmission such as Synchronous Ethernet, Fibre Channel, traditional SONET/SDH optical networking and high-clock-rate base stations. The VSCO also meets the needs of the latest generation of DACs and ADCs, which require a very clean reference signal.

The VS-705 is said to offer the lowest overall jitter noise in its class. Unlike the latest digital phase-locked loop (DPLL) technologies, which at a minimum have two times the phase jitter as well as spurious modes, the VS-705 uses a high Q SAW design, which results in spurious free phase jitter of <125 fs-rms, Vectron said. This allows transmission network engineers to achieve improved system BER performance and lower accumulated jitter generation over interconnected network equipment, added the company.

Pricing: $18 in quantities of 1,000 for the VS-705 (120 to 500-MHZ range with 50 ppm APR).
Availability: Currently available to order.
Datasheet: VS-705
