Holtek HT82V863R CCD Surveillance Camera Processor

10/05/2011

Holtek is pleased to announce the release of its new CCD surveillance camera processor, the HT82V863R. Compared with its previous 80-pin LQFP product, the HT82V862R, the new device is supplied in a more compact 64-pin LQFP package type. In addition to its original high-precision CCD timing generator, digital lock loop, TV encoder, video D/A converter, video amplifier, 1.8V regulator and LVR/POR circuits, this new image signal processor provides higher quality performance in areas such as low-luminance, colour and noise processing than its predecessor, the HT82V862R. Additionally, the HT82V863R also offers digital WDR, automatic back light compensation and digital line-lock functions to suit various customer requirements. With its advanced image processing technology, the HT82V863R contains an embedded MCU and uses an OTP type ROM for its program memory allowing it to meet the demands of customization and upgrades when compared with similar products which use a Mask type ROM for their program memory.

The HT82V863R and the HT82V846 CCD camera analog signal processor when used together with the HT82V805A CCD vertical driver operate as a complete surveillance camera chipset. All setup values, parking line and OSD menu can be saved to an external HT24LCxx EEPROM. The devices supports SONY, SHARP and other NTSC/PAL interlace Ye/Mg/Cy/G Complementary Color Mosaic Filter CCD sensors and provides various adjustable functions such as auto exposure, auto white balance, backlight compensation, high light suppression, contrast, saturation, brightness, color gain and color phase. These are all output as a composite video broadcast signal via the internal TV encoder, video D/A converter and video amplifier. To use the device in applications such as IP cameras and DVRs, customers can chose the standard CCIR656 digital output 80-pin LQFP HT82V863R to operate directly with the backend processor for further cost reductions.

To ensure users have an easy and convenient means of setting up the various options and parameters, Holtek provides a set of development tools and software specifically for HT82V863R where users can directly make adjustments and apply setups using Windows® graphic based software and a compact USB dongle. Additionally, Holtek also offers various CCD sensor setup examples and application circuits etc. to assist customers with rapid design implementation.
