The VPX336 is a 3U VPX module providing a complete timing solution. The 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)
The module 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 VPX336 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.
The VPX336 provides standard NMEA format via RS-232 for external devices.
