Precision GPS Reference ClockLow jitter GPS locked precision frequency reference 450 Hz to 800 MHz output This device outputs two synchronised low jitter reference clocks locked to GPS signal. Long term stability of output signal is defined by high accuracy of GPS Caesium references and theoretically 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
