  • Page 6: Introduction

    • As a PTP slave, the DXD-16 can generate legacy sync so that the legacy equipment locks to the network. • As a PTP master, the DXD-16 can lock to external sync sources such as WC, AES or video sync so that the network locks to the legacy equipment.

  • Page 7: Installation

    Out of the box, the DXD-16 is set to generate NTSC video sync, referenced to its internal crystal. This signal is sent to all 16 outputs. The 4 PTP ports are in the DISABLED mode. DHCP is activated on each port so IP addresses will be provided automatically by the router.

  • Page 8: I/O's Description And Cable Requirements

    4.5 ETHERNET PORTS 4 independent Gb Ethernet ports used to connect the DXD-16 to a network for PTP sync or to control the unit remotely and upload firmware from any computer on the network. Remote control and firmware update is from port #4 only.

  • Page 9: Front Panel Display & Led's

    5.1 FRONT PANEL DISPLAY The DXD-16 front panel has a large full color display giving access to all the unit’s parameters and settings. In the normal operating mode, information is presented on the display in multiple pages referred to as the ‘Main Rotation’...

  • Page 10: Display

    The PTP state of a port is determined by the BMCA. In a Master/Slave Group, if the DXD-16 is the grandmaster, all ports will assume that state; if not, one port will be ‘SLAVE’ the others ‘MASTER’. The state of ‘Independent Master’ is for ports set as such in menu 5.1 that won the BMCA.

  • Page 15: Menus Description

    • BNC INPUTS A and B are defined in menus 2.1 and 2.2 • PTP Mode is a little different. Selecting PTP Mode as the reference is required for the DXD-16 to be a PTP slave, i.e. ‘referenced’ to an external PTP Grandmaster. However, selecting PTP Mode means that the DXD-16 ports set to ‘Master/ Slave Group’...

  • Page 16: Sync Parameters (Menu 1.2)

    (see chapter 10 for more information on Alternate Reference). 7.3 BNC Outputs The DXD-16 generates 6 different reference signals simultaneously, each of them sent to a different group of BNC outputs, as described below. Each of these universal output groups can output WC, AES, Video Sync or 10MHz.

  • Page 17: Bnc Outputs 5-8 (Menu 3.2)

    • SET/AUTO: SET is the default value; AUTO is a special function, available only when the input reference is an audio signal. With AUTO, the DXD-16 automatically determines the incoming rate and uses that as the base rate. The advantage is that, if the rate of the input reference changes, so does the generated output, automatically.

  • Page 27: Time Of Day

    8. Time of Day Time of day is an essential component of the DXD-16. In a PTP network, the devices all need to know the Time of Day, i.e. year, month, day, hour and seconds, even nanoseconds, to achieve frequency and phase synchronization. At the heart of the DXD-16 is the Internal Time of Day Clock (TOD) &...

  • Page 28: Time Jam

    8.2.1 TIME JAM TO PTP When PTP is selected as the source of TIME JAM (menu 1.2), the DXD-16 will first lock its internal Time of Day clock to PTP. When that is achieved, the DXD-16 will release the PTP Lock and revert to the BNC source selected in the reference menu.

  • Page 29: Color Frame And Time Jam

    Main System Note that, in the scenario above, as both DXD-16's are locked to the same reference (Black Burst), the TIMES Status Page on DXD-16 #2 will confirm that the offset is ‘0 µsec’ and no drift is occurring (see 8.2.3 above).

  • Page 30: About Using The 'Set' Mode For The Reference Source

    When choosing SET for the rate of the reference source, there is the possibility that the selected rate will not match the measured rate (actual rate). If that is the case, the DXD-16 will still lock to the reference but the output frequencies will be adjusted proportionately.

  • Page 31: Reference Failure With No Alternate Reference

    If the DXD-16 is selected, one of the other 3 options will be displayed. The bottom line has the usual LOCK status, but in the case where the DXD-16 is the grandmaster (and is locked) it changes to "LOCKED / GRANDMASTER”.

  • Page 32: Ptp Port States

    • MASTER: in M/S Group mode (boundary clock) - state of the master ports (those distributing the master clock). • Passive: - in M/S Group mode - state of a Master port that ‘sees’ another master port from the same DXD-16 or, - in Independent Master mode - state of the port when the BMCA selects another unit as master (in its domain).

    Page 34 DXD-16 User Manual (rev 3.00) 15. General Information on PTP PTP is defined in the IEEE 1588 standard. This chapter covers some general information on PTP. For more details, please refer to the IEEE publication. 15.1 TIME AND PHASE Precise time information has always been crucial in traditional production and broadcast environments.

    field, making it ‘transparent’. The DXD-16 has 4 separate ports. Each can be set as an Ordinary Clock (independent Master-Only) or as part of a Boundary Clock (menu 5.1). For additional information on Boundary Clock, see 16.1 in the next chapter.

  • Page 37: Typical Ptp Set-Ups

    4 port Boundary Clock with external Grandmaster To set the DXD-16 as a Boundary Clock, set the Reference to ‘PTP Mode’ and the participating ports to ‘Master / Slave group’. In this example, Studios A, B & C do not communicate with the Grandmaster but rather with the DXD-16 ports.

  • Page 38: 4-Master Ports On A Single Domain With Gps Reference

    The PTP PORTS Main Rotation display page will show the state of MASTER (see 6.1.2). Alternatively, the reference could be ‘PTP Mode’ and the GPS set as ‘Local Ref When GM’ (menu 1.1). When the DXD-16 is selected as the Grandmaster by the BMCA, all ports are Grandmasters.

  • Page 39: Hybrid Sync Generator Accepting Multiple References

    In this example, ‘PTP Mode’ is the selected reference (menu 1.1) and ports 1, 2 & 3 are set to ‘Master/Slave group’ (menu 5.1) so the DXD-16 acts as a Boundary Clock. The networks connected to ports 1 & 2 (Master ports) are the primary and a secondary, the latter being used for redundancy.

    16.6 DISTRIBUTED PTP VS. INDIVIDUAL GRANDMASTERS WITH GNSS In this scenario, DXD-16’s are installed in several studios. In order to keep them in sync, 2 different options are available: the first illustration shows distributed PTP where all the DXD-16’s are PTP slaves to an external Grandmaster; in the second illustration, the DXD-16’s are all Grandmaster for their networks and each is locked to GNSS.

    • Announce Receipt Timeout: Although PTPv1 does not use Announce messages, a DXD-16 port in PTPv1 mode will use this value to determine whether or not PTPv1 SYNC messages have timed out (i.e. stopped arriving). Note that the timeout is measured in ANNOUNCE INTERVAL’s (above), whereas PTPv1 measures its SYNC message timeout in SYNC INTERVAL’s.

  • Page 42: Avb - Ieee 802.1As (Gptp)

    1⁄2 second [log -1] or less. • Min Delay Req Interval: This interval is not supported by PTPv1, but is used internally by the DXD-16 when in PTPv1 mode. You may continue to use the same setting as you would for PTPv2.

  • Page 43: Recommendations

    (menus 5.3.1, 5.4.1, 5.5.1, 5.6.1). • Priority Fields: If the DXD-16 is your preferred master clock, the simplest way to make it the Grandmaster is to set the Priority 1 field low enough to win the BMCA. However, it is also recommended that all candidate GMs would have the same Priority 1 value to avoid causing hierarchy issues as the Priority 1 field overrides any clock quality changes in the GM.

  • Page 44: Dscp Values And Priorities

    20.3 INTERNAL VLANS In an effort to filter out unwanted multicast receive packets, the DXD-16 makes use of two internal VLAN Id’s. Please note that the DXD will never tag any transmitted packets with these VLAN Id’s. Care should be taken however that the DXD should not receive VLAN-tagged packets using these Id’s.

    27. PTP Clock Identity vs MAC address The DXD-16 is a single clock with 4 ports. Each port has its own MAC address, but there can only be one PTP Clock Identity. It is conventional, but not required, that a PTP Clock Identity is created by inserting FF:FE in the middle of a MAC address. The DXD-16 follows this convention, but selects the Port 4 MAC address as the basis for the creation of its unique PTP Clock ID.
