The Orolia/Odetics/KSI TPRO-IP is a synchronizable timecode generator with integrated IP bus interface for precision time tagging and synchronization across networked systems. It automatically locks to standardized timecode signals and delivers microsecond-resolution time stamps via dual acquisition methods: software-initiated register reads or hardware event capture. The device compensates for propagation delay across transmission media, making it suitable for applications where temporal accuracy and event correlation are critical.
Technical Specifications
On-Board Clock
• Resolution: 1 µS
• Range: 366 days, 23 hours, 59 minutes, 59.999999 seconds
• Date Format: Integer (001–366)

• Stability (undisciplined): 2×10⁻⁷
Synchronization
Automatically locks to standardized timecode signals with status bits reporting sync state to the host. On loss of synchronization source, the clock free-runs from power-on. Propagation delay correction accommodates radio transmission (~3.3 µs/km), copper wire transmission (~5 µs/km), and input phase shift effects (~25 µs).
Time Tagging Methods
Software-initiated tagging via four 16-bit registers with freeze-on-read capability covering tens of milliseconds through hundreds of days. Hardware event capture via external logic pulse with 10-byte FIFO transfer minimizes latency for time-critical events such as radar transmit pulses.
