14-Bit GMSL Serializer with High Immunity/Bandwidth Mode and Coax/STP Cable Drive

Description

Create a design and simulate using EE-Sim^® tools:

The MAX96711 is a compact serializer with features especially suited for automotive camera applications. In high-bandwidth mode, the parallel-clock maximum is 116MHz for 12-bit linear or combined HDR data types. Line-fault circuitry detects open/short faults on the link cable.

The embedded control channel operates at 9.6kbps to 1Mbps in UART, I²C, and mixed UART/I²C modes, allowing programming of serializer, deserializer, and camera registers independent of video timing.

For driving longer cables, the IC has programmable pre/deemphasis. Programmable spread spectrum is available on the serial output. The serial output meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply range is 1.7V to 1.9V, and the I/O supply range is 1.7V to 3.6V.
