• ASIC Technology for Ultra Low Jitter
0.100 ps-rms typical across 12 kHz to 20 MHz BW
0.120 ps-rms typical across 50 kHz to 80 MHz BW
• Output Frequencies from 150 MHz to 1 GHz
• 3.3 V Operation
• LV-PECL or LVDS Configuration with Fast Transition Times
• Improved Temperature Stability over Standard VCSO (±20 ppm)
• Output Disable Feature
• 0/70°C or -40/85°C operating temperature
• Product is free of lead and compliant to EC RoHS Directive
Applications

1] The VS-702 power supply should be filtered, eg, 0.1 and 0.01uF to ground
2] See Standard Frequencies and Ordering Information tables for more specific information
3] Parameters are tested with production test circuit below (Fig 1).
4] Measured from 20% to 80% of a full output swing (Fig 2).
5] Integrated across stated bandwidth.
6] Tested with Vc = 0.3V to 3.0V unless otherwise stated in part description
7] Broadband Period Jitter measured using Lecroy Wavemaster 8600A 6 GHz Oscilloscope, 25K samples taken. See application note.
