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 28-lead surface mount package. It has a unique output disable and clock through feature to facilitate on-board testing.

By setting OD low, a test signal may be applied at CLKIN and fed through the VCO-600A to both the CLKOUT and CLKOUT to facilitate on board testing. The test signal input applied at CLKIN may be either an ECL or sinewave input (up to 1Vpp, AC coupled). CLKIN is biased internally to VBB (Vcc-1.3V) 2. An optional capacitor to ground can be placed on VBW to reduce the modulation bandwidth for narrow bandwidth phase-lock loop applications. The modulation bandwidth will be approximately 1/(12000*C)Hz, where C is equal to the capacitance in Farads. If the optional capacitor is not utilized, VBW becomes a no connect (NC) and the modulation bandwidth will be approximately equal to the nominal device frequency ÷1200. 3. By setting OD low, the outputs are disabled and CLKOUT is held Low while CLKOUT is held High. The threshold for OD is 1.4V above VEE. OD 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). If the OD feature is used during normal operation, then CLKIN should be tied through 10KΩ to GND to avoid any possibility of chatter on the CLKOUT outputs. Performance Characteristics Table 2.

The VCO-600A may be configured for PECL operation. All outputs and inputs including VC are referenced to Vcc 2. Output Levels are standard 10K ECL and are fully 100K ECL compatible. 3. Transition times are measured from 20% to 80% of a full 10K ECL level swing. 4. The modulation bandwidth is a function of nominal center frequency and may be adjusted down through the use of an external capacitor on pin 17.

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.
