Low-noise, quad channel GPSDO clock source 0.16 to 200 MHz
RigExpert Tokenblauser is a laboratory-grade, low-noise GNSS (GPS/Galileo) disciplined oscillator with four independent PLL-synthesized outputs. An addition, an auxiliary 10 MHz output in provided. All signals are 3.3V CMOS by default, with BNC connectors. The Tokenblauser is optimized to serve as a laboratory reference clock with 0.001 ppm (or better) stability, as well as for driving PLLs in RF/microwave/satellite applications.
Output: 0.16 to 200 MHz output (up to 350/710 MHz, depending on a PLL type).
Frequency control: from the LCD front panel or via USB connection to a PC, with 1 Hz step (very fine tuning is available with 1 ppt steps). Four memory profiles are available.
OEM opportunities: Use a 100×100 mm Tokenblauser module in your own product. Possible modifications include connecting external OCXO, GNSS receiver, using complimentary outputs with LVPECL/LVDS/HVSL/CMOS/SSTL/HSTL levels, etc. No programming skills are required. Source code and schematics are available for deeper modifications.
Included in the package:
– GPSDO in aluminum enclosure
– 12V power adapter (EU or US)
– GPS active antenna
– USB cable
– User’s manual
However, Tokenblauser was designed to be also a versatile platform for experimenters. The device is Arduino-compatible, and the firmware is open-source. With no or minimal changes in the code or in the hardware, an advanced user may:
– Connect the GPSDO to a computer for debug purposes or data processing (such as plotting ADEV/MDEV graphs);
– Modify the firmware to experiment with different PLL and FLL algorithms;
– Use own GPS modules and GPS antennas;
– Use different types of OCXOs and Rubidium oscillators.
