  • PLL-GPSDO 10 MHz
  • New version 2021 with very low phase noise
  • 10 MHz sine wave output
  • 1 PPM output
  • GPS NMEA RS232 output


  • Supply voltage: DC 11.7 - 13.8 V / <= 5 W
  • GPS antenna voltage: DC 5 V/0.1 A
  • Output 1PPS signal: square wave, 3.3 Vpp, synchronized to UTC
  • 10 MHz output: sine wave
  • 10 MHz output power: 11 dBm +/- 2 dB
  • RS232 output: signal GPS NMEA, 9600 bps

  • PWR LED indicator: indication of supply and GPS lock - blinking (GPS not locked), long light (GPS locked), no light (missing power supply)
  • ALM LED indicator: light (accuracy better than 0.1 Hz), no light (accuracy lower or the same as 0.1 Hz)

Rear panel

  • SMA female for GPS antenna with 5 V
  • Jack 3.5mm RS232 GPS NMEA 9k6
