DigiLink DLC170AD - Composite Video (NTSC/PAL) and Analog Audio to SDI
Conversion with Optical Transmitter
Convert composite (NTSC/PAL) to SDI (SMPTE
• Analog composite 75 Ohm video input BNC
• Automatic NTSC-M / PAL-B/G format detection
• 12-bit video composite to 10-bit component digital processing
• Advanced, adaptive 3D comb filter
• Comprehensive VBI data handling
• MPTE 259M SD-SDI 270Mb/s output
• Automatic and manual gain and equalization (100 m)
Convert analog audio to AES and embed into SDI
• Balanced 600 Ohm analog audio inputs (4)
• SMPTE 272M 24-bit, 48 kHz audio embedding
The DLC170AD converts analog video and audio to SDI (SMPTE
259M) and provides optical transport. Used with the DLC170DA, the design insures full TV-1 RS250-C “short haul” analog
performance over a true SMPTE 259M SD-SDI optical transport
The DLC170AD uses advanced high performance
12-bit video processing with adaptive 3D comb
filters to convert NTSC-M /PAL-B/G analog
composite video to ITU-R BT.601/656 compliant,
525 or 625 line, 4:2:2 component digital video.
Four channels of analog audio are converted to
24-bit digital signals and sampled at 48 kHz and
then embedded into the digital video per SMPTE
272M for a total of 4 analog channels. The audio
can be inserted into any one of the four groups.
Using the backplane to provide jumper free
connections, additional audio channel groups can
be added by cascading the DLC170AD digital output
to one or more DLC150E audio embedders. An SFP
installed into the final module provides the optical
output of the combined signals.
A front panel monitor jack can be selected to
output either analog or digital video. When set to
analog, the incoming analog video can be checked
for signal level and quality using conventional
analog video equipment. When set to digital, the
converted video in 270Mb/s SDI format with
embedded audio can be checked using digital
video test equipment.
