Introduction
Overview
The DAC-9213-R Multi-Definition SDI to Analog Component Converter with
Reclocked Outputs is a high-quality signal conversion solution for High
Definition (HD) and Standard Definition (SD) SDI signals and part of a growing
family of GearLite Multi-Definition (MD) self-contained, small brick format
modules.
The DAC-9213-R addresses program stream imaging requirements by
converting 10bit MD-SDI video to analog component video (multiple formats).
The DAC-9213-R has a full 10bit data path, with 11bit data processing.
The front panel of the DAC-9213-R chassis provides power and status LEDs for
visual reference. In addition, user-selectable switch settings are available to
select the preferred mode of operation.
The DAC-9213-R provides analog conversion of 525i, 625i, 720p, 1080i, and
1080p SDI signals (SMPTE 259M and 292M). The DAC-9213-R also has two
reclocked SDI outputs. Special measures have been taken to ensure excellent
return loss at both input and output. This ensures error-free performance with
short or long cables.
The DAC-9213-R is delivered with a universal power adapter and line cord
suitable for the country of use. Various mounting options are included that allow
a wide range of installation choices. The DAC-9213-R provides a
broadcast-quality MD-SDI component monitoring solution in a small,
stand-alone package.
