An Exquisite Evaluation Board from National Semiconductor

The LMH0356 Serial Digital Interface (SDI) reclocker is designed to recover a clean clock from a serial digital video signal which may be contaminated by jitter and to resynchronize the input video data to the recovered clean clock. The LMH0356 SDI reclocker accepts signals conforming to standards SMPTE 259M (C), SMPTE 292M, and SMPTE 424M.

ICL7135 Intersil Device Information

The Intersil ICL7135 precision A/D converter, with its multiplexed BCD output and digit drivers, combines dual-slope conversion reliability with ±1 in 20,000 count accuracy and is ideally suited for the visual display DVM/DPM market. The 2.0000V full scale capability, auto-zero, and auto-polarity are combined with true ratiometric operation, almost ideal differential linearity and true differential input. All necessary active devices are contained on a single CMOS lC, with the exception of display drivers, reference, and a clock.
