GPSDO (Global P
ositioning System Disciplined Oscillator), also known as GPS Tamed constant temperature crystal oscillator, GPS tamed clock, 10MHz standard signal source. Compared with the ordinary time base, it has higher accuracy, lower temperature drift and more stable output.
It is the use of GPS 1PPS signal
, microcontroller comparison, by the microcontroller output 16Bit PWM to control the isothermal crystal output accuracy, isothermal crystal frequency fine-tuning voltage is 0-5V, then the 1Bit PWM can control the output voltage is 0.000076V.
The length, width and height of the machine are 150*88*38mm(excluding protrudes), the front panel has a display screen and encoder, and the back panel has a 10MHz output interface, 1PPS output interface, GPS antenna interface, power switch and 12V DC power interface.
Application scenario:
GPSDO is suitable for high-end audio decoders, instruments, meters, frequency meters, signal sources and other devices with external 10MHz reference source input
