ADAS chipsets allow lighter in-car cabling

15 April 2014

Maxim Integrated’s automotive SerDes chipsets enable both shielded twisted pair and coax cabling, maximising design flexibility.

Engineers can design high-resolution ADAS (advanced driver assistance systems) with either traditional shielded twisted pair or lighter, less expensive coax cables using Gigabit Multimedia Serial Link (GMSL) SerDes chipsets from Maxim Integrated.
However, OEMs are beginning to turn from shielded twisted pair to coax cabling as it lowers cable cost and weight by up to 50%. With these SerDes chipsets, OEMs can continue using shielded twisted pair cables and seamlessly transition to coax cabling in future models using the same chipset. The chipsets drive 15ms of coax or shielded twisted pair cabling. 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.
The chips can also be used in high-resolution central- and rear-seat displays; they drive 1920x720 pixel displays with 24bit colour.
Each device operates over -40 to +105°C automotive temperature range. Pricing and evaluation kits are available to qualified customers on request.
