Features

• TV encoder targets the handheld devices and other appropriate display devices used in consumer products. (i.e. automobile)

• Support multiple output formats. Such as SDTV format (NTSC and PAL), HDTV format for 480p,576p,720p and 1080i, analog RGB output for VGA. Sync signals can be provided in separated or composite manner (programmable composite sync generation).

• Three on-chip 10-bit high speed DACs providing flexible output capabilities. Such as single, double or triple CVBS outputs, YPbPr output, RGB output and simultaneous CVBS and S-video outputs.

• 16Mbits SDRAM is used as frame buffer. Supporting for frame rate conversion.

• Flexible up and down scaling engine is embedded including de-flickering capability.

• Programmable 24-bit/18-bit/16-bit/15-bit/12-bit/8-bit digital input interface supports various RGB (RGB888, RGB666, RGB565 and etc), YCbCr (4:4:4 YCbCr, ITU656) and 2x or 3x multiplexed input. CPU interface are also supported.

• Support for flexible input resolution up to 800x800 and 1024x680.

• Pixel by pixel brightness, contrast, hue and saturation adjustment for each kind of output is supported. (For RGB output, only brightness and contrast adjustment is supported).

• Pixel by pixel horizontal position adjustment and line by line vertical position adjustment are supported.

• 90/180/270 degree image rotation and vertical or horizontal flip functions are supported.

• Macrovision 7.1.L1 for SDTV is supported in CH7025. (CH7026 is Non-Macrovision part.)

• MacrovisionTM copy protection support for progressive scan TV (480p, 576p CH7025 only)

• CGMS-A support for SDTV and HDTV

• TV/Monitor connection detect capability. DAC can be switched off based on detection result. (Driver support is required)

• Programmable power management.

• Flexible pixel clock frequency from graphics controller is supported. (2.3MHz –120MHz) Flexible input clock from crystal or oscillator is supported. (2.3MHz – 64MHz)

• Only slave mode supported.

• Offered in BGA or QFP package.

• Fully programmable through serial port.

• IO and SPC/SPD voltage supported is from 1.2V to 3.3V.

Description

The CH7025/CH7026 is a device targeting handheld and similar systems which accept digital input signal, and encodes and transmits data through 10-bit DACs. The device is able to encode the video signals and generate synchronization signals SDTV format for NTSC and PAL standards and HDTV format for 480p,576p,720p and 1080i. Analog RGB output and composite SYNC signal are also supported. The device accepts different data formats including RGB and YCbCr (e.g. RGB565, RGB666, RGB888, ITU656 like YCbCr, etc.). 16Mbit SDRAM is embedded in package. Frame rate conversion and Image rotation are possible.
