GNSS synchronisation board TMD1640

The SR1640 board provides high accuracy timing operations using a highly integrated GPS receiver. (± 1 µs accuracy for UTC) If the GPS signal is lost, the board continues the time generation using its own embedded oscillator in « Free-running » mode. 20 MHz ± 10 ppm, oscillator. The board is compliant with PCI 33 MHz, 5V standard, with “Target” type interface. The board also provides a 1 PPS GPS, local 1 PPS (in phase with the 1 PPS GPS signal) and 1 MHz signal. Outputs are compliant with RS422 standard. A dating input allows tagging external signal’s transitions. Input is compliant with TTL or RS422. The board can provide 1 interruption at each second (masking mode allowed) Information’s regarding : Time, Localisation, and Board status are available through PCI bus using a Windows DLL or Linux driver provided with the board
