Conexant's CX93610 features low cost, low power consumption and high image compression, making it ideal for wireless camera security solutions that require visual verification and dramatically reducing file size.
The CX93610 features an external CMOS image sensor that provides a variety of specialized JPEG encoding techniques to compress and store image data in an internal 512KB/256KB frame buffer. A 2:1 and 4:1 scaler is available for image resizing, and a 4:2:0 subsampling conversion further reduces image file size by up to 99%. With a microphone input and programmable allocation buffer, 2-bit or 4-bit ADPCM audio can be recorded simultaneously during image capture, providing a complete A/V solution and flexible frame buffer for audio and video data storage.
Controlled by a simple register group via the microphone interface, the CX93610 has a variety of interfaces including Serial Peripheral Interface (SPI), UART and I2C, allowing for a wide range of flexible microphone selections. This makes it easy to pair various types of wireless audio, and the base station processor for audio can be used to control the CX93610. The CX93610 features digital and analog photocell sensor inputs that facilitate proximity light measurements and use an on-chip LED driver to control external IR LEDs in low light conditions. Alternatively, an external calculation program can be used for photosensor measurements to save on external photocell costs.
Dr. Sailesh Chittipeddi, President and CEO of Conexant Systems, said: "Conexant continues to focus on providing innovative, integrated video solutions for security, surveillance and surveillance applications. Our latest encoders use DIFT JPEG Significantly reduce file size for faster transfer times and longer battery life."
The main features include:
• Integrated mixed-signal design for analog-to-digital image processing • On-chip 512KB/256KB frame buffer • Integrated analog components (ADC, LCD driver, DC-DC converter)
• Support for enhanced JPEG compression, >1MP CMOS sensor, processing of color and black and white images • JPEG, MJPEG, distinctive JPEG, DIFT encoded JPEG, reducing file size by up to 99% compared to standard JPEG
• Sleep mode low energy -10nA and low operating power (target <15mA)
• Frame-by-frame motion detection with programmable thresholds • Privacy mode • 12C, SPI, and UART interfaces for flexible connectivity • Register-driven devices • Selectable microphone input allows simultaneous recording of audio during image capture.
Conexant's 2012 International CES show in Las Vegas showcased its extensive video product line and a series of demonstrations including the CX93610.
When the CX93610 is ordered in quantities of one thousand, the price for a single piece is $5.
The positive active material is mainly made of nickel, and the negative active material is mainly an alkaline battery made of cadmium.The nickel-cadmium battery used in AGV car has large internal resistance and can be used for large current discharge.Compared with other kinds of batteries, nickel-cadmium batteries can withstand overcharge or overcharge, and the operation is simple and convenient.The discharge voltage is somewhat different according to the discharge current. In general, the discharge termination voltage of about 1.2v nickel-cadmium battery is 1.0v /CELL, and the actual operating temperature ranges from -20 degrees to 60 degrees. In this range, the discharge can be repeated for more than 500 times.
