SerDes chipsets serialise data, cut cabling, in automotive applications

You can design high-resolution advanced driver assistance systems (ADAS) with either traditional STP or lighter, less expensive coax cables using the Gigabit Multimedia Serial Link (GMSL) SerDes chipsets from Maxim Integrated.

Current vehicle designs use STP cables to drive data to automotive infotainment displays and cameras. However, OEMs are beginning to turn to coax cabling instead, as it lowers cable cost and weight by up to 50%. With Maxim’s SerDes chipsets, OEMs can continue using STP cables in their designs, and seamlessly transition to coax cabling in future models using the same chipset. The chipsets drive 15m of coax or STP cabling, providing the margin required for robust and versatile designs. The spread-spectrum capability built into each serialiser and deserialiser improves EMI performance in the link, without the need for an external spread-spectrum clock. Each serialiser can operate with any deserialiser in the family, allowing the use of different interfaces at each end of the link. In addition to driving ADAS applications, these chipsets can also be used in high-resolution central- and rear-seat displays, with up to 1920×720 pixel displays with 24-bit colour.

Each device operates over the -40°C to +105°C automotive temperature range; as with the previous generation of GMSL SerDes, HDCP compatible versions are available.
