January 2012 – Conexant Systems Inc., a developer for imaging, audio, embedded modem, and video surveillance applications, now introduced the CX93610, a low power High Definition DIFT JPEG-MJPEG Encoder that includes a 656 camera interface and optional microphone input. A monolithic mixed signal Application-Specific Standard Product (ASSP), the CX93610 is designed for monitoring and surveillance camera applications, including PIR sensor with video, video intercom/door phones, baby monitors and remote home monitoring.

Featuring low cost, low power and high image compression capability, Conexant’s CX93610 is ideally suited for wireless camera security solutions requiring visual verification, and can significantly reduce file sizes.

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. A 2:1 and 4:1 scaler is available for image re-sizing, with a 4:2:0 sub-sampling conversion available to further reduce image file sizes – by up to 99%. With a microphone input and programmable allocated buffering, a 2- or 4-bit ADPCM audio session can be recorded simultaneously during image captures, providing a complete A/V solution with a flexible frame buffer for audio and video data storage.

Key Features of CX93610 DIFT JPEG-MJPEG Encoder

  • Integrated mixed-signal design for analog-to-digital image processing
  • On-chip 512KB/256KB frame buffer
  • Integrated analog components (ADCs, LCD driver, DC-DC converter)
  • Supports enhanced JPEG compression techniques and >1MP CMOS sensors
  • Processes both color and black and white images
  • JPEG, MJPEG, Differential JPEG, and DIFT Encoded JPEG which reduces file sizes by up to 99 percent over standard JPEG
  • Low sleep mode power – 10nA and low operating power (target <15mA)
  • Frame by Frame Motion Detection with programmable thresholds
  • I2C, SPI, and UART interfaces for flexible connectivity
  • Optional microphone input records audio session simultaneously during image captures
