General Description
The CH7025/CH7026 is a semiconductor device
targeting for handheld market, surveillance camera
and automobile multimedia system. This device
accepts digital video signals through its 24-bit
input bus and generates NTSC, PAL, VGA or
HDTV (480p, 576p, 720p and 1080i) video signal
by its 10-bit DACs. In addition, CH7025/26 has an
embedded 16-Mbit SDRAM to support the CPU
interface.
CH7025/26
technology that can perform real-time video
rotations and frame rate conversions for incoming
video stream.
achieved by storing video data to the internal
SDRAM and applying scaling process if required.
CH7025/26 provides great flexibility for accepting
different video data formats including RGB and
YcbCr (e.g. RGB565, RGB 666, RGB 888, ITU
656).
The CH7025/26 is available in BGA or QFP
package.
