Bus-Level Timing PCIe Cards Keep Your Network In Sync

Masterclock manufactures a variety of timing PCIe cards to provide millisecond synchronization accuracy for your server or PC. Options for our timing cards include; extended temperature range, TCXO and OCXO time bases, and multiple input/output codes such as time code input from GPS, IRIG-B, SMPTE, EBU and IRIG-B12. 

The PCIe-OSC is a computer plug-in that provides very stable, accurate time and date information for a PC. After the initial setup the card generates reference time from an internal oscillator. It generates time information to your PC that is synchronized to within 165 milliseconds per day (one minute per year). 

PCIe Bus Level Timing

The PCIe-TCR version references time from time code generators, including SMPTE 24fps (Film), 25fps (EBU), 30fps NDF (Non-Drop Frame) and IRIG-B0 (unmodulated/pulse width modulated) and IRIG-B1 (amplitude modulated, 1kHz). When locked to a time code reference, the PC is synchronized to ± 2 milliseconds of the reference. 

The PCIe-GPS card receives reference time from atomic clocks orbiting in GPS (Global Positioning System) satellites. This greatly improves the accuracy of the PCIe card and your PC. GPS units require and include a pre-amplified GPS antenna that must be connected to the antenna coaxial cable and to the PC card bracket. Each PCIe-GPS is thoroughly tested with its external antenna prior to shipment. 

Masterclock’s HSO (High Stability Oscillator) option provides precision time and frequency for a wide range of applications. Affordable price and flexible order options make this a popular add-on for meeting critical time keeping during holdover (loss of primary reference such as GPS or time code). It is ideal for specialized applications requiring a precise frequency reference. The option maintains excellent holdover stability with drift less than 1 millisecond per day. 

All of Masterclock’s bus level timing cards are manufactured in St. Charles, MO and thoroughly tested prior to shipment. Software is included and each PCIe comes with a 5 year limited warranty.
