Maxim Integrated's Serial-Data Chipsets Transmit over Coax Cables, Lower Automotive Camera System Cable and Connectivity Costs by 50%

Maxim's automotive camera chipsets drive coax cables, reduce power use, process signals faster, and improve electromagnetic emissions compared to standard solutions using Ethernet cables.

San Jose, CA—September 20, 2012—Maxim Integrated Products, Inc. (NASDAQ: MXIM) introduces two high-speed serialization/deserialization (SerDes) chipsets that significantly lower the costs for automotive camera systems. Operating over standard coax cables, the MAX9273/MAX9272 (22 bits) and MAX9271/MAX9272 (16 bits) chipsets do not need the extra wires of an Ethernet setup to power a camera. With today's high-end automotive camera systems often using multiple cameras and cables, this coax solution represents a 50% reduction in cable and connectivity costs compared to current standard twisted-pair (STP) solutions.

Maxim's new camera chipsets operate at very high data rates (1.5Gbps), which is critical for today's fast video and megapixel image transmissions. Using coax cables, the chipsets do not need to compress data and thus process images immediately—a crucial requirement for safety applications like sign recognition, collision avoidance, and night vision. In comparison, Ethernet-based solutions require data compression, which requires external components, resulting in higher costs, power consumption, and power dissipation. The chipsets' reduced power consumption, from both the elimination of external components and low 75mA supply current, helps to prevent camera heat sensitivity issues. Finally, the coax cables on the chipsets are more robust than Ethernet cables; they provide better shielding, which reduces emissions and interference. Compared to solutions using Ethernet cables, the end result now is a cleaner, crisp image from the camera.

Key Features
  • 1.5Gbps serial data rate ensures high image quality
  • Lower (75mA) power consumption allows plastic encapsulation of camera
  • Error detection and correction are ideal for camera safety applications
  • For added user convenience, the chipsets drive both coax and STP cables
Industry Commentary
  • "The market for automotive park assist cameras is forecast to grow at a significant double digit rate over the coming years. Safety is the main factor driving demand, notably the 'Kids and Transportation Safety Act' in the US; however, the increasing use of large, color displays within vehicles is also an enabler. IHS Automotive forecasts global demand for park assist cameras to exceed 11 million units in 2013." Helena Perslow—Senior Analyst for IHS Automotive
