Description
The VS-502 is a SAW based voltage controlled oscillator that operates at the fundamental frequency of the internal SAW resonator. This direct approach enables this series to achieve low phase noise and jitter performance at high output frequencies and over wide operating temperature range. The oscillator is housed in a hermetically sealed J-lead surface mount package offered on tape and reel. As an option, it has an output disable to facilitate on-board test

See Standard Frequencies and Ordering Information Parameters are tested with production test circuit Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310. Output levels are standard 100K PECL compatible and measured from 20% to 80% of a full output swing (Fig 1). Not tested in production, guaranteed by design, verified at qualification. Integrated across 12 kHz to 20 MHz, or 50 KHz to 80 MHz per GR-253-CORE Issue3. Tested with Vc = 0.3V to 3V for 3.3V supply, Vc = 0.5V to 4.5 V for 5V supply, Vc = 0.5V to 11.5V for 12V supply Maximum frequency occurs at room temperature
