The standard V1641 SDI Frame synchronizer performs the same basic functions as the
V1640 except that it includes a 2 x 1 SDI input switch. This is useful, for instance, when
switching between the SDI output of an ADC converter and a direct SDI signal source. It
provides synchronization of the selected SDI signal to an external analog video reference.
Both horizontal and vertical offset from the reference can be user adjusted and the
output can be set to go to black or to freeze if the input fails. A ‘Minimum Delay’ mode is
provided. In this mode the reference input is ignored and the delay through the unit is less
than a few microseconds. The unit will automatically switch to ‘Minimum Delay’ mode
if the input system standard (625 line 50Hz or 525 line 60Hz) is different to that of thereference.
A Video Processing Amplifier (option /VP) can be programmed into the unit during
manufacturing test. This provides control of video gain, chroma gain, luminance blacklevel and hue shift.
An internal Audio Processor (option/AP) can be programmed into the unit during
manufacturing test. The processor re-samples and delays a single embedded audio group
from the SDI input. The audio delay tracks the video delay through the synchronizer. The
input audio group number can be selected and re-assigned at the output. The facility to
blank all other input groups is provided. Alternatively, if one of the following audio I/O
sub-modules is fitted, the unit can be set to blank all input or output groups.
One of four audio I/O sub-modules (options /AA, /AD, /DA or /DD) may be fitted to embed
and/or extract a single audio group. Both analog and digital AES types are available.
Note: If an audio sub-module is required/fitted, then option /AP must be included.
