  • Page 37: Theory Of Operation

    Theory of Operation The TSync-PCIe board's architecture essentially consists of input ref erences, which are used as sources of 1PPS synchronization and/or time-of-day (TOD) and date information, and for disciplining an internal oscillator. The TSync-PCIe takes the synchronous clock, a 1PPS and time-of-day (TOD) and date to create output references that act as time references for other devices.

  • Page 38: Input References

    IRIG formats can be amplitude modulated, or they can be digital signals at various car rier and clock rates. The TSync-PCIe architecture supports IRIG inputs with Formats A, B, and G. It supports inputs and outputs using modulation frequency values of pulse width code, also known as DCLS (0), and sine wave amplitude modulated coding.

  • Page 39: Table 6-1: Irig Input Reference Formats

    Table 6-1: IRIG Input Reference Formats The TSync-PCIe supports the IRIG B variant NASA36 as an input format, as well as the IEEE C37.118-2005 (which is an IRIG B format with extensions as an input format). The IEEE C37.118-2005 specification supersedes IEEE 1344-1996. The TSync-PCIe is backward com patible to IEEE 1344-1996 by compliance with IEEE C37.118-2005.

  • Page 40: External 1Pps Reference

    The TSync-PCIe board provides built-in references that support specialized user applications. 6.1.4.1 Host Reference The TSync-PCIe can be set to use the host as the source of date and time information, while another input reference is required to serve as the source of frequency input. This allows the host to provide time to the board while providing a means to determine and indicate whether that time is valid for synchronization.

  • Page 41: Clock Subsystem

    Clock Subsystem The clock subsystem is the heart of the TSync-PCIe timing architecture. Time is maintained in the board’s hardware and incremented in 5- nsec units, while sub- second information is tracked. Time, from seconds through years, is incremented based on the internal 1PPS derived from the selected input reference.

  • Page 42: Output References

    6.4.1 IRIG Output The TSync-PCIe board provides one IRIG AM and DCLS pair output. The IRIG output is a rolling count of the initial value of the system time until synchronized. The board drives the IRIG AM out put from an associated IRIG DCLS output and outputs the exact same format (except for the AM modulation).

  • Page 43: 10-Mhz Sine Wave Output

    Table 6-3: IRIG Output Reference Formats The TSync-PCIe allows the user to select the IRIG B variant NASA36 as an IRIG output. It also supports user-selection of IEEE C37.118-2005 as an IRIG output. This is an IRIG B format with extensions.

  • Page 44: General Purpose Input/Output

    6.5  General Purpose Input/Output General Purpose Input/Output The TSync-PCIe board has four general purpose input (GPIO) pins and four general purpose output (GPIO) pins. The General I/O subsystem provides a mechanism to generate or time stamp external events, to match times and generate a signal, to create Heartbeat pulses, or to create square wave clock signals synchronous to the internal timing system clock and to the 1PPS signal from the input reference.

  • Page 45: Leds

    Interrupts The host bus has one interrupt line available from the TSync-PCIe. All interrupt sources destined for the host bus are multiplexed on the single interrupt line. All interrupts are masked on startup, but can be unmasked using the host bus interrupt mask register.
  • Page 46 6.9  Interrupts 6.9.1.4 Local/μC Bus FIFO Overflow This interrupt is driven when the FIFO from the local bus to the microcontroller bus is over flowed. It is based on the rising edge of the FIFO’s overflow flag. 6.9.1.5 μC/local bus FIFO Data Available This interrupt is driven when the FIFO from the microcontroller bus to the local bus is no longer empty.
