• GNSS for Time Sync
GPS Disciplined Oscillator

Model GF-180TC
  • Discontinued Products

GF-180TC is ultra compact and low cost GPS Disciplined Oscillator. 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-180TC Receives GPS signals and generates 1PPS (pulse per second) synchronized with UTC as well as 10MHz sine wave and square wave coherent to 1PPS.

  • GNSS (Timing, Automotive/Industrial)

Features

Possible to generate 1PPS synchronized with UTC as well as 10MHz sine wave and square wave coherent to 1PPS

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

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.

Designed especially for wireless broadband base stations for CDMA, WiMAX and LTE.
