Toshba announces 2nd gen 3D comb filter/video decoder for flat-panel TVs, STBs

Toshiba America Electronic Components, Inc. (TAEC), a committed leader that collaborates with technology companies to create breakthrough designs, has announced the introduction of a second-generation, high-performance 3D comb filter front-end processor targeted at advanced analog and digital televisions, audio/video systems, set-top boxes and other video-processing systems. Designated TC90103AFG, the highly integrated device provides a complete solution for analog-video processing. It integrates a 3D comb filter for NTSC, a multi-standard 3-line comb filter, 3D noise-reduction functions, a digital multi-standard decoder and 5 Mbits of embedded DRAM for frame-buffer memory in a compact 144-pin LQFP package.

According to Shardul Kazi, vice president of the ASSP Business Unit at Toshiba America Electronic Components, Inc., “Our highly integrated single-chip solution provides outstanding video quality with its high-quality, analog-video luma (Y) and chroma (C) separation, multi-standard color decoding and YCbCr output in the digital domain. The integration of embedded DRAM reduces design complexity and overall system cost while increasing reliability. This second-generation product complements other Toshiba solutions for video-processing and digital-TV applications and extends the company's leadership in the video-processing segment and digital-consumer electronics market.”

Highlights of the TC90103AFG include the following:

  • Features built-in, high-performance 3D and 3-line comb filters and 3D Y and C noise-reduction functions
  • Y/C separation: 3D YCS (3.58 NTSC), 3-line YCS (NTSC/PAL) and band-pass filter (SECAM)
  • 3DNR: CVBS (3-line comb mode), S-video, YCbCr, RGB

  • Integrates an adaptive digital multi-standard color decoder; this multi-format decoder capability makes it suitable for use in a worldwide chassis.
  • Uses adaptive multi-standard detection and sync processing
  • Incorporates 5 Mbits of embedded DRAM for frame-buffer memory
  • Features 10-bit and 8-bit analog-to-digital converters to support various input interfaces, including CVBS, S-Video, YCbCr and 10-bit 4fsc digital CVBS
  • Features digital ITU-R656 and ITU-R601 output for high-quality pictures
  • Integrates signal-/noise-level detection, data slice functions for world regions (ID-1, WSS, CCD) and a Macrovision signal-detection circuit
  • Features analog automatic gain control (AGC) with sync AGC and peak AGC
  • Integrates an RGB fast blanking mixer
  • Incorporates numerous picture-improvement functions
  • Y: V enhance, LTI, sharpness, noise cancel, contrast and brightness
  • C: take-off filter, ACC, color gain, CTI and noise cancel
  • Includes support for SCART interface
  • Offers Gemstar G-guide support
  • Has I2C bus control
  • Power supply: 3.3 volts (V), 2.5V and 1.5V
  • Housed in a 144-pin LQFP package (LeadPb-free1)
