the CX93610 is a monolithic mixed signal application-specific standard product (assp) designed for low cost and low power motion detection surveillance camera applications, as well as home monitoring/remote monitoring applications. used with an external cmos image sensor, the CX93610 offers a variety of specialized jpeg encoding techniques to highly compress and save image data in an internal 512kb/256kb frame buffer. an optional 2:1 and 4:1 scaler is available for image re-sizing. in addition, a 4:2:0 sub-sampling conversion is available to further reduce image file sizes. with a microphone input and programmable allocated buffering, a 2- or 4-bit adpcm audio session can be recorded simultaneously during image captures. the stored images and audio data are then passed on to an external microprocessor for uploading to a desired medium. the CX93610 is controlled through a simple register set via the microprocessor interface, and the variety of available interfaces (serial peripheral interface [spi], uart, and i 2 c) allow for wide flexibility in microprocessor select ion. with both digital and analog photocell sensor inputs available, the CX93610 can facilitate the measurement of ambient light and use an on-chip led driver to control an external infrared led during low-light conditions. with low cost, low power, and high image compression capability, the CX93610 is ideally suited for security and monitoring applications.
