PT8 is a Multistandard Video encoder IP core with support for 960H and 1280H outputs.


PT8 is a multistandard Video encoder supporting PAL-M/N/B/D/G/H/I and NTSC-M/J as well as 960H (Sony Effio) and 1280H formats.

The intellectual property core accepts Y,Cb,Cr formatted data, in either 3x8 or 3x10 bit format, and the associated 27MHz clock (36/54MHz for 960H/1280H) and synchronising signals, and it encodes this data to a 10 bit, digital composite video signal, which can be used to directly drive a digital to analogue converter, modulator or other output device.

  • PAL-M/N/B/D/G/H/I, NTSC-M/J and 960H/1280H outputs.
  • High quality video output: <1% DG and <1deg DP, <1% K-factor and <-70dB SNR.
  • Requires Y,Cb,Cr video input and 27MHz clock (36MHz/54MHz for 960H/1280H), H/V/F syncs.
  • Fully programmable for non-standard inputs and outputs.
  • Output is up-sampled to 27/36/54MHz straight binary digital composite video.
  • 12 bit chroma modulator.
  • Switchable Sinx/x correction.
  • Pre-programmed register settings for common standards.
  • Standard 8-bit control interface bus.
  • Demonstration board available (SB5).
