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

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.
