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."

VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation. ESD Ratings Model Human Body Model Charged Device Model Minimum 500 500 Conditions MIL-STD 883, Method 3015 JESD 22-C101 Recommended Solder Reflow Profile 220 Temperature (Deg C) 183 150 60 60-90 45-60 Time (s) VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The conditions a device can withstand are well understood and devices can be subjected to the profile above. This profile shows a ramp up condition to prevent thermal shock, a preheat period in which the flux is activated, a ramp up to 183C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down. The time above 183C should not exceed 60 seconds and the peak temperature should be no more than 220C for 10 seconds. The VS-550's are hermetically sealed so an aqueous wash is not an issue.
