  • Page 3: Introduction

    Page 3 1. Introduction The DXD-16 Universal Clock is a PTP Grandmaster, merged with a precision Reference Generator. On the PTP side, 4 independant Ethernet ports arte included. The DXD-16 can be either a PTP Grandmaster, slave or boundary clock. The precision multi-format reference generator provides a total of 6 independent video syncs and audio clocks simultaneously.

  • Page 4: I/O's Description And Cable Requirements

    ☛ Use standard 75Ω BNC coaxial cables (see DXD/SDI manual). 2.5 ETHERNET PORTS 4 independant 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.

  • Page 5: Installation

    • Registration card 3.2. INSTALLING THE DXD-16 The DXD-16 is designed to be mounted in a standard 19” rack. It requires 1U in height. Usual precautions should be respected when wiring the DXD-16: use high qual- ity cables with good shield to guarantee a good signal transmission. Keep your cables as short as possible.

  • Page 6: Quick Start

    Connect the power supply to the Power A jack and plug the IEC cable into a wall out- let. The DXD-16 will turn on as soon as power is connected. 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 current DOWN selection is highlighted (black letters, white background). Pressing the [ DOWN button passed the lowest item on the list rotates back to the top of the list.

  • Page 11: Menus Description

    - BNC INPUT A - BNC INPUT B - INTERNAL BNC INPUTS A and B are defined in menus 1.2 and 1.3; INTERNAL is the DXD-16 oscillator, TCXO (or OCXO, if that option is installed). Additional fields are included in this menu: - SIGNAL and RATE: these are status field indicating the status and the rate of the selected reference, as defined in menus 1.2 and 1.3.

  • Page 12: Outputs

    Menu 1.2 lets you select the type of input connected to INPUT A and its rate. - SIGNAL: WC, AES, 10 MHz or Video Sync - LEARN/SET: LEARN is the default value. With LEARN, the DXD-16 determines the incoming rate; with SET, the user determines the incoming rate. For more information on Learn vs.
  • Page 13 - 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 14: System Configuration

    The DXD-16 has non-volatile memory holding the current settings. This includes all DXD-16 settings such as rate and reference selections as well as output assign- ments. This memory is continuously updated so that, when the unit is turned on, it is in the same condition as it was when powered down.

  • Page 17: Source Reference Failover

    12. Source Reference Failover In the event of failure of the external reference, the DXD-16 has 2 different scenarios to insure that the Sync outputs remain safely uninterrupted. 12.1. REFERENCE FAILURE WITH AN ALTERNATE REFERENCE Menu 1.1 allows for the second BNC input to be used as an alternate reference.

  • Page 18: Firmware Updates

    All 4 are equal from a PTP standpoint but firmware updates and remote control are from port #4. Connect port # 4 of your DXD-16 to your network and point your browser to the IP address of your DXD-16. A simple firmware loader page will appear.

  • Page 19: Uploader

    3 menus are available while in the Uploader mode: Network, Brightness and Reboot. Point your browser to the IP address of your DXD-16. A page similar to the regular Firmware Loader page described above will appear. To restore your unit, use the BROWSE button to locate the firmware file on your hard disk (.upld) and click UPLOAD.

  • Page 20: Appendix

    ”PAL-” stands for slow PAL. 14.2. APPENDIX B: AUDIO BASE RATES The DXD-16 has 2 different audio base rates, defined in menus 2.5 and 2.6. Those are used to generate the audio signals, WC and AES. The table below shows the different rates available, based on 3 different sampling frequencies: 32KHz, 44.1KHz and 48KHz.

  • Page 21: Multiplied Rates

    • -4%: The rate of PAL is 25 fps while the rate of film is 24fps. That is a 4% difference (25 x 96% = 24). The DXD-16 provides 0.1% and 4% pulled down and pulled up rates, and a combination of both coefficients down and up as well for multiples of 48KHz. Only -0.1% is provided for multiples of 41.1KHz.
