Operating at 3.3Vdc, the TFLD546E2 will maintain ±4.6ppm frequency tolerance over 20 years. The TFLD546E2 is offered in a surface mount package for automated assembly. FEATURES 3.3V OPERATION OVERALL FREQUENCY TOLERANCE: ±4.6ppm OVER 20 YEARS. TEMPERATURE RANGE: 0 to 70°C LOW JITTER <1pS RMS TRI-STATE ENABLE/DISABLE FUNCTION PAD 2 SURFACE MOUNT PACKAGE TAPE AND REEL PACKAGING PACKAGE CHARACTERISTICS Package TABLE 6.0 Non-hermetic package consisting of an FR4 substrate with grounded metal cover. PROCESS RECOMMENDATIONS TABLE 7.0 Soldering Process Wash RoHS 5/6 compliant. See solder profile page 2. Ultrasonic cleaning is not recommended. Note: 1) Inclusive of calibration, frequency vs. temperature stability, supply voltage change, load change, shock and vibration, 20 years aging. 2) Oscillator output is enabled with no connection on pad 2. Output is at high impedance when disabled.
