SDI Digital to Analogue Converter - DAC271

Features

Overview

The DAC271 digital to analogue converter translates a SDI source to composite video, YC, RGB and YUV outputs. The DACs are ideal for attaching to the rear of a monitor to handle a serial digital input. Whilst the composite and YC signals are primarily designed for monitoring, the YUV component and RGB outputs provide signals which are suitable both for monitoring and for recording on Betacam SP and other analogue component VTRs.

As an engineering tool, a pair of video converters provide an easy way to produce an SDI signal from a normal analogue signal and to check the presence of an SDI signal without the need for an SDI monitor. The DAC271 complements the ADC271.

An EBU colour bars generator is incorporated into the DAC271 digital to analogue converter. Switching quickly through the video output format selector switch positions invokes bars mode. Once invoked, the switch is used to select the output format in the usual manner (colour bars are available on all outputs, composite, YC, YUV and RGB). Quick switching again returns the DAC271 to normal digital-analogue conversion mode.

Both PAL 625/50Hz and NTSC 525/60Hz signals may be fed to and from the ADC / DAC. The television standard is determined by the position of an internal link.
