The LT 443D-SD SD-SDI Unit adds the 525/625 line format
SD-SDI signal (4:2:2 component signal) output capability to
the LT 443D mainframe. Various functions (e.g., ID charac-
ter, simple motion pictures, embedded audio, NATURAL
picture pattern*) are provided.
*1: The NATURAL picture function is only usable when the
LT 443D-70 Option is installed in the mainframe.
Installing the LT 443D-AA Analog Audio Unit in the LT 443D
mainframe can output analog audio signal (two systems).
Output characteristics (e.g., output level, frequency) can be
independently set for each output system.
The sound sampling frequency is synchronized with the
video signal of plug-in unit installed in the mainframe.

The LT 443D-BL Analog Black Signal Unit adds the 20 HDTV format
analog tri-level sync signal, 525p/625p analog sync signals, and
NTSC/PAL black burst signals output capability to the LT 443D main-
frame.
Three independent output systems (six outputs, two outputs per sys-
tem) are provided to output multiformat black sync signal.
The format and output signal timing can be respectively set each output. The ten-field black signal with ID conforming to the SMPTE 318M
standards is also available.
The entire range of timing can be set for the 525p/625p analog sync
signals and NTSC/PAL black burst signals in 54 MHz clock steps.
The entire range of timing can also be set for the HDTV analog tri-
level sync signal in 74.25 MHz or 74.25/1.001 MHz clock steps.
