The LT4610 is a 1U full rack size sync generator that can operate in synchronization with GPS, PTP, CW, and internal reference signals, as well as Genlock that supports external analog video synchronization signals.
It supports analog video sync signals, AES / EBU digital audio output, word clock, and time code, and also supports 3G / HD / SD-SDI output and 12G-SDI output compatible with 4K and 8K.
In addition, it supports the PTP grand master function and PTP slave function, and can manage the optimum synchronization system according to the system.
The genlock function is equipped with a STAY IN SYNC function that retains the phase when an abnormality occurs in the input analog video synchronization signal, and the power supply unit performs redundant operation, enabling highly reliable system construction.

Features

  • Genlock Function
    Various output signals can be synchronized by applying NTSC/PAL black burst signals, which are analog video sync signals, and HDTV tri-level sync signals.
    NTSC/PAL black burst signal with field reference pulse and NTSC black burst signal with 10 field IDs are also supported.
  • Stay-in-Sync and Slow Lock Functions
    A Stay-in-Sync function is available in case errors occur at the genlock input. In addition, a slow lock function is available to reduce the shock that occurs when genlock is performed again based on stay-in-sync. This makes it possible to construct an extremely reliable synchronization system.
  • Analog Video Sync Signal Output
    Six analog video sync signals can be output. The phase of each output can be adjusted independently.
    NTSC/PAL black burst signal with field reference pulse and NTSC black burst signal with 10 field IDs are also supported.
  • GPS/BDS Synchronization
    GNSS antenna can be connected to generate and output signals by locking to the frequency and clock obtained from the GPS or BDS.
  • PTP
    PTP synchronization corresponds to the grandmaster and slave functions.
    You can choose reference signal from PTP, GPS, analog BB or internal.
  • Time Code I/O
    The ATC (LTC) can be embedded in LTC outputs from internal time, GPS, LTC, and VITC time information, and SDI signal outputs, or VITC in analog video synchronous signal outputs.
  • Triple-rate SDI Ready
    SDI signal output supports 3G-SDI (level A and level B), HD-SDI (including dual link), and SD-SDI. There are two independent outputs of SDI signal at output terminals. The pattern and phase can be set separately for each. (However, only a single output is available for 3G-SDI level B and HD dual link.)
  • Lip Sync Patterns
    This option can output lip sync patterns in which the video and audio are synchronized. In combination with a waveform monitor that features a lip sync function, such as the Leader’s LV5600, it is possible to measure the offset between the video and audio in SDI signal transmissions.
  • 12G-SDI Support
    Four output connectors can be added to support 12G-SDI, 3G-SDI (level A, level B) and HD-SDI (including dual links).
    In addition, it corresponds to the 8K video signal by adding 8K software option.
  • Audio Embedding
    The LT 4610 can embed 32 channels (stream 1, stream 2, 4 channels each × 4 groups) of audio signals for 3G-SDI level B and 16 channels (4 channels × 4 groups) of audio signals for 3G-SDI level A, HD-SDI, and SD-HDI. The frequency, level, and the click can be set for each channel.
  • AES/EBU Signal Output
    The LT 4610 can output a 48 kHz AES/EBU signal synchronized with the video signals. It is also equipped with a muted AES/EBU signal output.
  • Word-Clock Signal Output
    The LT 4610 can output a 48 kHz word-clock signal synchronized with video signals.
  • Real Time Clock
    The real time clock is backed up by a battery. There is no need to reset the clock even when the power is turned off and on.
  • Ethernet
    SNMP is supported. When an error is detected, a TRAP is generated. Further, the LT4610 can be controlled through HTTP.
  • Preset Memory Function
    Up to 10 presets can be saved. Convenient registered presets can be recalled during operation. The
    LT 4610 can be started with the same settings every time.
  • External Memory Support
    Logo data and preset data can be written and saved from the front panel using USB memory devices.
  • Redundant Power Supply
    Two power supplies are built in to provide redundancy. When errors occur in power supply units, alarms are indicated on the LT4610 front panel. Errors can also be output as alarms using SNMP traps.

    • Time Code I/O
      The time code generator can run in free run mode based on internal time information. It can also embed ATC (LTC) in SDI signal output or VITC in analog video sync signal output based on a GPS, LTC, or VITC time information.
      It also features a holdover function, which retains the phase and frequency of the output signal when GPS signals or CW signals are lost. Further, when LT4610 is locked to GPS, it can also be used as an NTP server.
    • CW I/O
      The CW I/O connector not only receives 10 MHz CW but also outputs 10 MHz CW or 1PPS, whichever is selected.
    • LTC I/O
