The Connor-Winfield T501G is a 5x7mm
Surface Mount, Temperature Compensated
Crystal Oscillator (TCXO). Operating at
3.3Vdc, the T501G will maintain ±4.6ppm
frequency tolerance over 20 years. The
T501G is offered for applications where small
size and Stratum 3 performance are required.

Notes:
1. Inclusive of Hold Over stability, supply voltage change (±5%), aging, 24 hours
2. Inclusive of calibration @ 25°C frequency vs. change in temperature, change in supply voltage
(±5%), load change (±5%), reflow soldering process and 20 years aging.
3. Leave Pad 8 unconnected if enable / disable function is not required. When tri-stated, the output
stage is disabled but the oscillator and compensation circuit are still active (current consumption
≤
1 mA).
