GPS Tame Clock, GPSDO, 10MHz/1PPS Frequency Reference Source
GPSDO, also known as GPS tame clock, GPS tame signal reference source, compared with ordinary clock reference source, has higher accuracy, lower drift, relying on GPS satellite signals to automatically calibrate the accuracy, long life and life cycle will not appear accuracy error.
Suitable for:
High-end audio decoders, digital turntables and other audio equipment with external 10MHz clock input.
Various high-end instruments; short-wave radio with external 10MHz reference source input; high-precision frequency meter, high-precision signal source and other instruments.

△10MHz output is 4-way, including 2-way square wave and 2-way positive rotary wave.
△From the new design of optimized PCB wiring, pay more attention to phase noise optimization, and all the components to choose a higher standard components, higher quality SMA interface, just to achieve the ultimate effect.
△Adopting special buffer chip for clock, the phase noise noise is as low as -160dBc.
△Using DAPU 022B series ultra-low phase noise OCXO, the phase noise is as low as -165dBc.
△Comprehensive phase noise of the whole machine is as low as -160dBc.
△Adopt AIR551G dual-frequency multi-mode GPS, support GPS, BeiDou, Galileo and other satellites.
△Optimized hardware and software design, 16-bit DAC segmentation control, control gain up to 600 +, integrated jitter as low as ± 2ns.

Parameters:
Power supply voltage: DC7-13V
Power consumption: warm-up <12W, work <5W
Frequency accuracy: 1e-10 (locked); 2e-11 (after 24 hours of taming)
Short-term frequency stability: 5e-13
Output level: 13dBm±1dB@50Ω
Output waveform: 2-way square wave + 2-way sine wave (can be customized 4-way all sine rotary wave or 4-way all square wave)

Indicator status description:
PWR: total power indicator.
ALM: status indicator; blinking means GPS signal is abnormal; off means GPS signal is normal but not locked, 10MHz output accuracy is not reached; always on means locked, 10MHz output accuracy is reached.
GPS: GPS power indicator.
1PPS: 1PPS output indicator, blinking once per second when GPS signal is normal.

Standard equipment includes a host, a power supply, a GPS antenna (standard cable length 3 meters, optional 5 meters)
Warm reminder: because everyone's equipment with a different line, so is not equipped with a clock output line, the clock output line to purchase their own, the output of this device for the SMA external screw hole interface.

Trivia: How to choose between sine wave and square wave? For external reference of instrumentation or replacement of internal reference source of audio equipment, square wave type is required. For the external reference clock of high-end audio equipment (which is usually shaped), you can use a square wave or a sine wave.
