ILC170AD - Analogue Video and 4 Ch Audio to SD-SDI

The ILC170AD converts analogue video and audio to SDI (SMPTE 259M) and provides optical transport. Used with the ILC170DA, the design insures full TV-1 RS250-C “short haul” analogue performance over a true SMPTE 259M SD-SDI optical transport link.

The ILC170AD uses advanced high performance 12-bit video processing with adaptive 3D comb filters to convert NTSC-M /PAL-B/G analogue composite video to ITU-R BT.601/656 compliant, 525 or 625 line, 4:2:2 component digital video. Four channels of analogue 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 analogue 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 ILC170AD digital output to one or more ILC150E 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 analogue or digital video. When set to analogue, the incoming analogue video can be checked for signal level and quality using conventional analogue 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.
