GS1500 - HDTV Serial Digital Deformatter

Datasheet Summary

Description

When interfaced to the Gennum GS1545 HDTV Equalizing Receiver or GS1540 Non-Equalizing Receiver, the GS1500 performs the final conversion to word aligned data.

The device performs NRZI decoding and de-scrambling as per SMPTE 292M and word-aligns to the incoming data stream.

Features

  • SMPTE 292M compliant.
  • standards detection/indication for SMPTE 292M levels A/B,C,D/E,F,G/H,I,J/K,L/M.
  • NRZI decoding and SMPTE descrambling with BYPASS option.
  • line CRC calculation, comparison.
  • selectable line based CRC re-insertion.
  • H, V, F timing reference signal (TRS) extraction.
  • selectable flywheel for noise immune H, V, F extraction.
  • selectable automatic switch line handling.
  • selectable TRS and line number re-i.
