These SAW filters are high-Q quartz devices that enable the circuit to achieve low phase jitter performance over a wide operating temperature range. The dual oscillator is housed in a hermetically sealed J-lead surface mount package offered on tape and reel. It has a frequency select function that enables either “Frequency 1” or “Frequency 2.” FS Gnd Vc Vectron International, 267 Lowell Rd, Hudson NH 03051-4916 Page 1 of 7 Tel: 1-88-VECTRON-1 Website: www.vectron.com Rev: 11Apr06 VS-550 Voltage Controlled SAW Oscillator Electrical Performance Parameter Frequency Nominal Frequency Absolute Pull Range Linearity Gain Transfer (See Pg 5) Temperature Stability Transition Time Supply Voltage Current (No Load) Outputs Mid Level Swing Current Rise Time Fall Time Symmetry Spurious Suppression Jitter (See Pg 5) Control Voltage Input Impedance Modulation Bandwidth Operating Temperature Package Size 1. 2. 3. 4. 5. 6. 7. 8.

Also, exposure to these absolute maximum ratings for extended periods may adversely affect device reliability. Functional operation is not implied at these or any other conditions in excess of those represented in the operational sections of this datasheet. Permanent damage is also possible if any device input (Vc or FS) draws greater than 100mA.

The VS-550 family is capable of meeting the following qualification tests: Environmental Compliance Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2016 Handling Precautions Although ESD protection circuitry has been designed into the VS-550 proper precautions should be taken when handling and mounting. VI employs a human body model (HBM) and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation.
