The Orolia/Spectracom TPRO-PCI-66U is a PCI-based timecode reader and generator delivering precision time synchronization for laboratory and system integration environments. This card reads multiple timecode formats with autodetection, generates IRIG-B output, and captures external events with microsecond-level accuracy. It operates from the PCI bus and supports both 33 MHz and 66 MHz clock frequencies across 5.0V and 3.3V backplanes.
