2025 GPSDO Pro 5CH GPS Disciplined Oscillator 10MHz 1PPS GPS Clock for Audio Decoders High-end Devices Sinewave Square wave

Features:
- It is the latest version - PLUS version
- 4-channel 10MHz outputs, including 2-channel square waves and 2-channel sine waves
- Redesigned and optimized PCB layout, paying more attention to phase noise optimization.  Higher standard components and higher quality SMA interface are used to achieve the ultimate effect
- A clock-specific buffer chip is used to reduce phase noise. The noise is -160dBc
- The DAPU 022B series ultra-low phase noise OCXO is adopted with phase noise as low as -165dBc
- The comprehensive phase noise of the whole machine is as low as -160dBc
- It adopts AirM2M AIR551G dual-frequency multi-mode GPS, and supports satellites such as GPS, Beidou and Galileo
- Optimized hardware and software design, 16-bit DAC segment control, control gain up to 600+, and comprehensive jitter as low as ±2ns

Application:
- High-end audio decoders, digital turntables and other audio devices with external 10MHz clock input.
- All kinds of high-end instruments and equipment. Shortwave radio with external 10MHz reference source input. High-precision frequency meter, high-precision signal source and other instruments.

Specifications:
- Power supply voltage: DC7-13V
- Power consumption: < 12W for warm-up; < 5W while working
- Frequency accuracy: 1E-10 (locked); 2E-11 (after taming 24 hours)
- Short-term frequency stability: 5e-13
- Output level: 13dBm±1dB at 50 Ω
- Output waveform: 2-channel square waves + 2-channel sine waves (4ch sine waves and 4ch square waves can be customized)

State of Indicator Lights:
- PWR: Main power indicator.
- ALM: Status indicator. Flashing indicates an abnormal GPS signal; Off means that the GPS signal is normal but not locked, and the 10MHz output accuracy is not reached; Staying on means that the signal is locked, and 10MHz output accuracy has been achieved.
- GPS: GPS power indicator.
- 1PPS: 1PPS output indicator. It will flash once per second when the GPS signal is normal.

Package Included:
- 1 x Main unit
- 1 x Power supply
- 1 x GPS antenna (with 3m/9.8ft cable)

Attention:
- Because everyone's equipment uses different wires, it is not equipped with a clock output cable. The cable should be purchased separately. The output of GPSDO PLUS is an SMA female connector.

Tips: How to choose sine wave and square wave?
The square wave type is required for external references to instrument-like equipment or to replace internal reference sources for audio devices. For high-end audio devices with external reference clocks (high-end audio devices are typically shaped), users can use square or sine waves
