Description
This product is based on the GPS+ADC+VCXO+CKBUFF architecture, using GPS module high-precision time information, controlled by FPGA, and ultimately driving DAC to calibrate the improved voltage controlled constant temperature crystal oscillator VCXO with extremely low phase noise, obtaining a 10M standard output with extremely low noise, high precision, and an output amplitude of approximately 3V. This product was originally designed to complement software defined radio products. After four years and five or six improvements after designing the finished product, it was found that its performance far exceeded expectations. In addition to being used as a high-precision synchronous clock in communication, it can also be used as a conventional 10M standard frequency source.
Specification
GPS lock time: less than 40 seconds after power on.
Preheating time: 2 minutes.
Clock stability lock time: less than 3 minutes.
Connect the GPS antenna and face it towards an open area, which can provide stable frequency output after 3 minutes.
Absolute frequency accuracy: less than 5PPB.
5 channels of 10M clock output, 2 channels of PPS output, with a standard 3.3V logic COMS output level.
Frequency Accuracy refers to the deviation between the actual output frequency and the nominal frequency, which is less than 5PPB.
Startup Time refers to the time required from power on to stable output, which is about 3 minutes.
Like all other constant temperature clock products, the longer the power is on, the more stable it becomes.
Output waveform: Square wave, peak to peak value 3V.
Power Consumption: Supply voltage DC7-12V, conventional DC5521 interface, power consumption not exceeding 8W
Operating Temperature Range: Tested to work normally at -19~90 degrees Celsius.
Package include
1 x GPS clock
