Required Accessories

The LT4448 is a changeover unit that connects two input signals, detects abnormalities by the amplitude of the input signal when a malfunction occurs, etc., and automatically switches the signal to the spare side. It has eleven pairs of BNC and LTC channels, and it corresponds to SDI signal, NTSC/PAL black burst signal, HD ternary synchronization signal, AES/EBU digital audio signal, word clock signal, and LTC signal. The LT4448 can be used in combination with 4610 sync generator.

 
  • Features

    • It is equipped with 11 channels (1 set with PRIMARY input, BACKUP input, OUT PUT) on one unit.
    • Switching by relay is adopted for switching between primary signal and backup signal of channels 1 and 2. To switch between the primary signal and the backup signal of channels 3 to 11, high-speed switching by electronic switch is adopted, and LTC can switch three primary signals and backup signals.
    • The type of input signal can be selected. For channels 1 and 2, select from SDI signal (3G, HD, SD), NTSC / PAL black burst signal, HD 3 value synchronizing signal, and for channels 3 to 8 select from NTSC / PAL black burst signal and HD 3 value sync signal Yes, channels 9 and 10 are exclusively for AES / EBU digital audio signals. Channel 11 is dedicated to word clock signal (TTL input). The LTC channel is dedicated to the LTC signal (2 V pp differential input).
    • Each of the LTC channels can have 2 inputs (primary, backup) and 3 lines / 1 output (output) for each of 3 lines. Also, you can connect with LT 4610 (sink generator) with LTC cable (optional).
    • Depending on the rise time of the system signal source to be connected, you can select from about 1 minute / about 4 minutes the time from turning on the power to starting fault detection.
    • The power supply is duplexed, improving reliability. In case of abnormality, it will be notified by alarm.
