A staple product of bus level timing, Brandywine's PCI card with optional GPS and IRIG B provides precision time with zero latency to the host computer over the PCI bus using the reference signal of your choice: IRIG B, 1PPS, IRIG A, NASA time codes, GPS or Have Quick.  This PCI-Syncclock32 has a built-in microprocessor that automatically synchronizes the clock to the reference signal input. This timing card can be used as an IRIG-B timecode generator by setting the initial time via the PCI bus. The PCI syncclock timing module can free run and be set by commands from the host over the PCI bus.


The basic PCI Syncclock 32 card is one of Brandywine's standard and most ordered products with its full selection of options to customize it to fit your specific needs. Below is a list of the many features the PCI Syncclock32 has to offer:

  • 3/4 length board (1/2 size available w/o GPS input)
  • Optional Have Quick synchronization input
  • IRIG's A and B and NASA 36 time code inputs
  • 1PPS sync input
  • IRIG B output option
  • 1PPS and time code inputs are redundant
  • Single-slot including GPS option
  • Zero latency time reads
  • External Event input (optional eight or sixteen inputs)
  • Match Time output
  • Programmable Heartbeat rate

The PCI Syncclock32 card is one of the great standard PCI boards in the timing business and Brandywine is continuously working on keeping our products with the newest technology.

Optional Disciplined Oscillator
Enhance performance by selecting optional disciplined TXCO or OXCO. By locking the oscillator to the synchronising time source, the oscillator is automatically calibrated, ensuring that a precise timebase is always available. During periods where there is no synchronising time source, the performance of the module reverts to the oscillator specification. When the input signal is available the oscillator will return to normal disciplining.

58 bits of BCD time data are available to the host computer using two zero latency time reads. The time message contains units of microseconds through units. A status word is available using an additional read.

Pulse Rates
The PCI-SyncClock32 provides three user programmable pulse rates. Two pulse rates, Clock Low and Clock High, are available on the multi-pin connector. The third rate generator provides heartbeat timing to the host computer.

Optional GPS Receiver
The optional on-board GPS Receiver receives and decodes transmissions from GPS satellites, allowing the timing system to accurately synchronise to Universal Coordinated Time (UTC). Automatic leap year, leap second correction and accurate positional information are additional benefits provided by the GPS option.
