Manufactured by MtronPTI, this surface-mount oscillator uses specially processed crystals to achieve a consistent long-term stability of ±0.1 ppm over the temperature range 0 to 70C and ±0.2 ppm over the range -40 to 85C, with minimal frequency shift after reflow.
The TCXO has an operating frequency range of 8 to 52 MHz and delivers a low g-sensitivity of 0.6 ppb/g, with phase noise typically -156 dBc/Hz at 100 kHz offset. Drawing 1.5 mA at 13 MHz, the device provides a significant advantage over similarly specified OCXOs for power-sensitive applications.
Shock and vibration performance has been tested in accordance with the requirements of MIL-STD-202, and the oscillator incorporates protection circuitry to guard against damage from electrostatic discharge. Housed in either a 7 x 5 mm 10-pad SMT package or a 14-pin DIP, the M616x is available in 3.0, 3.3 and 5.0V versions and can be specified with a choice of HCMOS or clipped sine wave outputs.
