The M.2-PTSyncMaster module provides its host system with a zero-latency Precision Time Master reference. It accepts various reference signal inputs, including 1 PPS, IRIG, NASA, or HaveQuick. The clock supports IRIG A, B, or NASA 36 input formats and allows for user input of reference signal delay information. An IRIG B code generator is also included. Advanced features such as Event Time input, Match Time, and Heartbeat Timing offer the host system comprehensive Precision Time Master reference capabilities. These features enable precise synchronization and timing, making it suitable for applications requiring high accuracy and reliability. The M.2-PTSyncMaster module continuously measures the time error between its onboard clock and a reference input, adjusting for propagation delay. An adaptive gain loop uses the residual error to adjust the oscillator’s frequency, minimizing error. If the incoming time code is missing or corrupted, the onboard clock is updated using a TCXO until the input code becomes available. The module features an Event Time input to capture the exact time of external events with a resolution of 100 ns. The Match Time feature can initiate or terminate processes with a resolution of 1 μs, asserting a Match Ready status when the clock’s time matches the user-input start time. The output is terminated under user control or when a pre-programmed stop time occurs. Additionally, a programmable Heartbeat Timing generator is available over a range of 2 to 65,535, with a selectable divider for 3 MHz or 100 Hz. Time data are provided via 58 bits of BCD, allowing for zero-latency time reads that include units from microseconds to years, along with an additional status byte.
