Very high cost two stage power supply voltage regulation offer very stable power source. And its new tcxo suspension bed design do lower down output noise which may come from mechanical vibration.
Features of this precision clock module:
1. Clock generator : 0.3ppm 33.8688 MHz TCXO /Waveform: TTL/CMOS / Phase Noise: -125dBc/1KHz /Aging: 2ppm per year.
2. Suspension TCXO socket bed design.
3. Two stage voltage regulator :
First Stage by discrete transistor circuit and constant current design for very fast and stable output.
Second stage by LT1117-5 regulator for lowest ripple noise.
4. High speed and low output impedance wave buffer for clock signal.
5. High quality parts used in this module like Phlips BC 036 and 037 capacitor, Dale military resistor and high speed/low noise diode.
6. This module should feed 9~12vac 0.5a power input
