详细说明： CH7034B Fulll Datasheet Rev1.25 CH7034B HDTV/VGA/LVDS Encoder Supports multiple output display formats – including Component YPrPb(HDTV), LVDS and analog RGB (VGA) • Three 10-bit high speed DACs • HDTV output support up to 1080p • Analog RGB (VGA) support up to 1920x1080 resolution • Single channel LVDS 18-bit transmitter supports i nput resolution up to 1366x768 • Support scaled and bypassed video streams output from VGA/HDTV and LVDS interfaces simultaneously • Supports panel protection, power sequencing and backlight on/off. PWM is available for controlling LCD brightness • TV/Monitor connection detect capability. DACs can be switched off through programming internal registers • On-chip SDRAM frame buffer to support frame rate conversion. • Programmable adaptive de-flickering filter • Supports 8/12/16/18/24-bit parallel interface inputs for either RGB format or YCbCr format (ITU-R 656 or ITU-R 601). 80/86 MPU interface and DE only mode are also supported. • Wide range of input resolutions support for up to 1366x768 (i.e. 640x480 720x480, 720x576, 800x600, 1024x600, 1024x768, 1280x800, and etc.) • Image display rotation support at 90/180/270 degree or flipped in horizontal/vertical position • Pixel-level color enhancement for brightness, contrast, hue and saturation adjustment for HDTV • Horizontal/vertical position adjusted through serial port programming • Pixel clock input frequency support for up to 165 MHz • Flexible crystal or oscillator clock input frequency (2.3MHz – 64MHz) • IO Supply Voltages from 1.2V to 3.3V and SPC/SPD Supply Voltages from 1.8V to 3.3V. • Programmable power management • Device fully programmable through serial port or can automatically load firmware from Chrontel Boot ROM (9904AMF) • Offered in a 88-pin QFN package Chrontel CH7034B is specifically designed for a portable system that requires connections to LCD display, High Definition Television (HDTV) or RGB (VGA) monitor. With its advanced video encoder, flexible scaling engine and easy-to-configure video interface, the CH7034B satisfies manufactures’ product display requirements and reduces their costs of development and time-to-market.
