    DXD-16 - Overview

    A PTP Grandmaster Merged with a Precision Reference Generator

    DXD-16 Universal GPS-capable Clock combines PTP and legacy Sync to keep traditional Audio/ Video equipment and the IP network in perfect sync, making the DXD truly Universal.

    IEEE 1588 Network Sync
    The PTP module supports PTP v2, PTP v1 (Dante) and gPTP (AVB). The DXD-16 can be either a PTP Grandmaster, slave or Boundary Clock. Precision Time Protocol (PTP) has been broadly adopted as the network synchronizing standard, which means that the DXD-16 can work in a number of systems. Several PTP profiles are included: AES67, SMPTE 2059 and gPTP.

    As a Boundary Clock, the DXD-16 can follow an external Grandmaster on one of its attached networks, synchronize its internal clocks to that Grandmaster, and distribute the same Grandmaster time in its role as PTP master to the remaining attached networks. Alternatively it can itself fulfill the function of Grandmaster and be PTP master on all attached networks.

    Four Gigabit Ethernet ports (RJ45) are available. The different ports can be used independently or as primary and secondary pairs. Each network connector supports an electrically and logically independent network, with the DXD-16 acting as a PTP timing bridge. The DXD-16 is not a network switch, and for security reasons, no information flows from any network port to any other.

    Customize Your Units with User-Assignable BNC Outputs
    The DXD-16 generates up to 6 independent sync signals simultaneously and routes them to the 16 BNC outputs. These user-definable outputs offer great flexibility compared to dedicated outputs as they can be configured for any of the generated references, video or audio. This includes all standard SD and HD video sync formats (Black Burst and HD tri-level sync), word clock and AES-3id (at rates from 32 to 384 KHz, plus all the necessary pull-up/down, including 24:25 conversions, even VSO) and 10MHz. With the time code option installed, LTC is also included

    Accurate and Versatile Clock Generator
    A high-accuracy internal crystal oscillator (TCXO) provides a very stable frequency reference (+/- 1ppm). An optional oven-controlled oscillator (OCXO) can be installed.

    External legacy signals can also be used as reference, such as Word Clock, AES, Video Sync (SD & HD) or a 10MHz tone. The generated outputs have extremely low jitter. The output rates are independent from the reference rate which means that any rate can be generated from any reference such as 59.97 from 25FPS for example.

    PTP Slave or Grandmaster
    The DXD-16 can be a PTP slave or a PTP Grandmaster giving the operator exceptional flexibility: As a PTP slave, it can generate legacy sync so that the legacy equipment locks to the network; As a PTP master, it can lock to an external legacy sync source so that the network locks to the legacy equipment; As a stand-alone master, locked to its internal oscillator or optional GPS, it provides sync to the network via the PTP port and to the legacy equipment via the BNC outputs, simultaneously.

    GNSS / GPS
    An optional GPS receiver can be installed in the DXD-16. GPS not only provides an extremely accurate timing source, it also enables DXD's in remote locations to be locked and in phase with one another. Additionally, with the GPS option, the DXD will have a higher priority as a PTP Grandmaster.
