Description

Programmable from: 400 Hz to 810 MHz output !!

 

Low-jitter GPS-locked precision frequency reference.......... 

This device outputs low-jitter reference clock frequency-locked to GPS signal.
(output can be set to 400 Hz to 810 MHz !! )

Long term stability of output signal is defined by high accuracy of GPS Caesium references and approaches 1x10-12.

Short term signal quality is defined by internal TCXO clock source providing high-quality, low phase noise clock signal with sub-picosecond RMS jitter.

Digital PLL allows main output reference frequency to have almost any value between 400Hz and 810MHz.

Output signal is a square wave at 3.3V CMOS levels with 50 Ohms characteristic impedance. Output drive level can be adjusted.

 

The device comes in a carry case with USB cable and an active GPS antennna with magnetic base and Configuration Software. (WINDOWS)

Output power level (measured at 10MHz, fundamental power channel):
+10.3dBm, drive setting 32mA
+9.9dBm, drive setting 24mA
+9.0dBm, drive setting 16mA
+6.4dBm, drive setting 8mA

Typical phase noise at 10MHz output:

-70 dBc/Hz at 1 Hz
-100 dBc/Hz at 10 Hz
-125 dBc/Hz at 100 Hz
-145 dBc/Hz at 1 kHz
-150 dBc/Hz at 10 kHz
-153 dBc/Hz at 100 kHz
-155 dBc/Hz at 1 MHz

Power draw through 5V USB is 250mA

 

Operation requires presence of GPS signal, however temporary loss will be tolerated seamlessly. Active or passive antennas are supported. An active antenna with 3 metre cable is provided with the device but can be substituted if necessary. GPS acquisition time after power-up is around 30 seconds. If GPS signal is lost, digital PLL will maintains best estimated output frequency based on historical data. On reacquisition of GPS lock, output is seamlessly brought back in sync with GPS reference. Entry and exit of frequency hold is glitch-less.

All frequency and output settings are fully user-configurable via USB connection from Windows PC.

GPS clock can be powered via mini USB connector from a PC, USB phone charger or USB power bank. USB connection to Windows PC is required only for one-off configuration. All settings are stored inside the device and maintain values when off. The SMA antenna connector voltage is 3.3V. Most active antennas work on a wide range - 2.5v to 5v because they have analogue LNA inside that is not sensitive to power level.

 

 Examples of use include:
 10.000MHz, 1.000MHz or other frequency reference for lab equipment and instrumentation
 reference for transmitter equipment - HAM equipment, propagation beacons, frequency markers, VHF, UHF and microwave converters.
 reference for receiving equipment, RTL SDRs (28.8MHz) and band scanners
 calibration source for radio receivers
 master clock for audio and video equipment, DACs and studio recording gear
