VPX336

Complete VPX Timing Module with IRIG-B, GPS, 1PPS, IEEE1588, SyncE

Description:

VPX336 is a 3U VPX module providing a complete timing solution. It VPX336 has 1PPS, Sine Wave clock, IRIG-B input, IRIG-B out and a GbE.

The module can take its upstream time/frequency from one of:

  • GPS (freq and time + location/velocity/other metadata)
  • IEEE1588 PTP (freq and time)
  • IRIG-B AM/DCLS/Manchester (freq and time)
  • 1PPS (freq only)
  • Sine Wave Clock In (freq only)
  • Synchronous Ethernet (freq only, can be combined with IEEE1588 PTP)

The module can provide its downstream time/frequency to all of:

  • IEEE1588 PTP (freq and time)
  • IRIG-B AM/DCLS/Manchester (freq and time)
  • 1PPS (freq only, can be combined with NMEA for freq and time)
  • NMEA (time only, can be combined with 1PPS for freq and time)
  • Clock Out (freq only)
  • Synchronous Ethernet (freq only)

VPX336 has an on board 5 x DPLL. The DPLL synchronizes 1Hz to 750MHz, providing frequency with jitter cleaning of noisy references. Complies with ITU-T G.8286, G.813, G. 812 and Telcordia GR-253/GR-1244. The module will automatically holdover upon loss of reference while still providing its time/frequency outputs to the rest of the system. The DPLL allows for fast lock to 1HZ input taking only 3 to 60 seconds depending on the reference input compared to 10 minutes or more for previous solutions.

The board has RS-232 routed to the front as well as to the rear (P2 connector). The rear RS-232 has an option to be level shifted or simply as LVCMOS.

VPX336 provides standard NMEA format via RS-232 for external devices.
