Dual/Single-Picture Video Processors

Product Overview

The TC90195XBG incorporates a frame memory to display two independent pictures. It can display two asynchronous  video  signals  simultaneously  and overlay graphics signals from a system-on-a-chip (SoC) on video signals.

The TC90175XBG under development is a single-video processor without a frame memory. Both the TC90195XBG and the  TC90175XBG incorporate a video decoder, support  various analog and digital video input formats, and allow optimal picture adjustment according to the specific LCD panel. The output stage has a T-Con, which adapts to LCD panels from multiple manufacturers.

TC90175XBG [Under development]

  • TC90195XBG family (pin-compatible)
  • Supports Full-HD panels
  • Two video output channels: LVDS (for WVGA to Full-HD) and LVTTL (for QVGA to WXGA)
  • Dividing into two pictures and simultaneous dual-LCD display
  • Incorporates a newly developed area-adaptive gamma correction circuit to improve visibility.

TC90195XBG

  • Two video output channels: LVDS (WVGA to WXGA+), LVTTL (QVGA to WVGA)
  • Many variation display method like two pictures composition and dividing into two pictures
  • simultaneous dual-LCD display

Product Introduction

Full, Multi-Standard Video Decoder IC: TC90106FG

The TC90106FG is a full, multi-standard video decoder, which supports not only a C-Video input, but also D1 and D2 component inputs. For picture-quality enhancement, the TC90106FG provides a baseband tint function that allows tint adjustment for all video formats up to D2 resolution. In addition to the ITU-R BT.656 output interface, an 8-bit serial (SAV/EAV insertion) output is selectable for a D2 video input, with the clock rate converted from 27 MHz to 54 MHz.

2-Channel Multi-Standard Video Decoders IC: TC90105FG

The TC90105FG is a two-channel video decoder, featuring various picture adjustment functions, such as an HV & diagonal (HVD) enhancer, color management and dynamic YC gamma correction. It allows image rendering, according to the videos from automotive cameras.

HVD enhancer: Provides diagonal edge enhancement in addition to the traditional edge enhancement in the horizontal and vertical directions. The HVD enhancer in the TC90105FG features the ability to apply a greater amount of edge enhancement while minimizing an artificial look.
Color management: Provides the capability to increase the saturation of selected colors. Its objective is to improve visibility by making particular colors such as red more prominent. The TC90105FG allows you to select three colors and program their saturation levels.
Dynamic YC gamma correction: Suppresses black and white collapsing to improve visibility by optimally adjusting the gamma correction curve for luma according to images. The TC90105FG maintains the balance between the luma and chroma levels by adjusting the chroma gain based on the luma gamma correction.

This is the block diagram of the 2-channel full, multi-standard video decoder, TC90105FG.
