VCSO Reduces Need for Jitter Attenuating Clock Cleaners

Fri, 08/27/2010 - 7:35am

Vectron International announced its VS-709 dual frequency voltage controlled SAW oscillator. It offers a 50 percent reduction in jitter performance compared to its predecessor, the VS-751, comes in a 5.0 mm x.7.0mm x 1.8 mm package and achieves <120 fsec of rms jitter over the offset bandwidth of 12 kHz to 20 MHz. The VS-709 is optimized for use in phase-locked loop (PLL) circuits that require jitter filtering in a wide range of high-speed data transmission applications such as 10GbE, 40GbE, 100GbE, OTN (Optical Transport Network), Synchronous Ethernet, and Sonet/SDH. This voltage controlled SAW oscillator operates at the fundamental frequency from one of the two internal SAW filters. The SAW filters are high-Q Quartz devices that enable the circuit to achieve low phase jitter performance over a wide operating temperature range. A divider circuit is deployed for output frequencies less than 600 MHz. The selectable dual oscillator is housed in a hermetically sealed leadless surface mount package and offered on tape and reel. It has a tri-state Frequency Select function that provides one of three conditions: Frequency 1, Output Disable, or Frequency 2.
