GF-180TC Frequency Generator :

The GF-180TC is ultra compact and low cost GPS-steered Frequency Generator. It has VCTCXO as a base oscillator, which is overwhelmingly ultra compact and low cost comparing with OCXO. High stability frequency is
generated with locking on the timing signal from GPS receiver.

The GF-180 Receives GPS signals and generates 1PPS (pulse per second) synchronized with UTC as well as 10MHz sine wave and square wave coherent to 1PPS. In “Fixed Observation Point Mode”, one satellite signal is enough to output accurate 1PPS and 10MHz. The crystal oscillator is maintenance-free. The integration of GPS receiver and Crystal Oscillator realizes small footprint. It
allows you to easily mount on the motherboard.

Features:

• Ultra compact/Low cost
  The integration of GPS receiver and crystal oscillator realizes
  ultra compact size and low cost.

• GPS
  The GF-180TC has Furuno built-in Time Transfer GPS receiver
  (equivalent to the GT-80). The chip is mounted directly on the
  board and the GPS CPU performs integrated control TCXO.

• TCXO
  The GF-180TC adapts TCXO (Temperature compensated crystal
  oscillator). The accuracy by itself is 10-6approx.(1ppm). The
  excellent high accuracy is realized by the combination with GPS.

• Coherency
  The GF-180TC realizes the coherency within ±10ns accuracy
  between the falling edge of 1PPS and the zero crossing of
  10MHz.

• Fixed Observation Point Mode
  If the GF-180TC is operated at the fixed position such as the
  base station and the transmitting station, the GPS receiver
  calculates its position and then use the averaged position for
  5hours after power-on as fixed observation point.

• RoHS compliant

• Customizable
  The GF-180TC is customizable to meet customer demands
  depending on applications. Please feel free to contact if you
  need different of frequency or frequency accuracy.
