VS-500A

Product Data Sheet VS-500A Voltage Controlled Saw Oscillator Features Output Frequencies from 155 MHz to 800 MHz Low Jitter < 1 ps rms in the 12kHz to 20MHz range < 1ps rms jitter in 50kHz to 80MHz range 3.3V (see VS-500) or 5.0V operation Ideal for clock smoothing, frequency translation, clock and data retiming applications 10K ECL, PECL logic levels with fast transition times Complementary outputs Low profile, surface mount package Output disable feature www.DataSheet4U.com Applications 2.5, 10 Gbit/s FEC and standard SONET/SDH Clock Smoothing and Frequency Translation 10 Gigabit Ethernet Clock Smoothing Frequency Translation Description The VS-500A is a SAW based voltage controlled oscillator that operates at the fundamental frequency of the internal SAW filter. This resonator is a high-Q quartz device that enables the circuit to achieve low phase jitter performance over a wide operating temperature range. The oscillator is housed in a hermetically sealed J-lead surface mount package offered on tape and reel. It has an output disable to facilitate on-board testing.
