Description The VS-709 is a Voltage Controlled SAW Oscillator that 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. Features • Industry Standard Package, 5.0 x 7.0 x 1.8 mm • 5th Generation ASIC Technology for Ultra Low Jitter 120 fs-rms (fN = 622.08 MHz, 12 kHz to 20 MHz) 105 fs-rms (fN = 622.08 MHz, 50 kHz to 80 MHz) • Output Frequencies from 150 MHz to 1000 MHz • Spurious Suppression, 90 dBc Typical • 2.5V or 3.3V Supply Voltage • LVPECL or LVDS Output Configurations • Tri-State Frequency Select (F1, OD, F2) • Compliant to EC RoHS6 Directive
