Product Data Sheet VS-500A Voltage Controlled Saw Oscillator Features • Output Frequency @ 155 MHz to 1 GHz • Low jitter, 1.5ps rms (typical) for 622.080 MHz, 3ps rms (typical) for 155 MHz • J-type package - smallest 622.080 MHz package available • 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 Applications • OC192/OC48/OC12/OC3 Clock Smoothing • STS96/STS48/STS12/STS3/STS1 Clock Smoothing • Frequency Translation Description The VS 500A is a SAW stabilized, voltage controlled oscillator that operates at the fundamental frequency of the internal SAW filter. This filter is a high stability, 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. It has an output disable to facilitate onboard testing. VS-500A Voltage Controlled SAW Oscillator Pin Information Table 1. Pin Function Pin Symbol Function 1 VC VCXO Control Voltage 2 3 4 5 6 OD GND Output COutput VCC Output Disable Case and electrical ground VCXO Output VCXO Complimentary Output Power Supply Voltage (5.0 V ±10%) 1. By setting OD low, the outputs are disabled and OUT is held high while Complementary OUT is held low. The threshold for Output Disable is 1.4V above VEE. Output Disable should not be driven above mid supply and during normal operation, should be left floating (use with an open collector or 3-State gate for interfacing with standard logic).

VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance=1.5Kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes.
