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

The MAX96705A is a compact serializer with features especially suited for automotive camera applications. It is function and pin compatible with the MAX9271. In high-bandwidth mode, the parallel-clock maximum is 116MHz for 12-bit linear or combined HDR data types.

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.

The MAX96705A is available in a 32-pin (5mm x 5mm) TQFN package with 0.5mm lead pitch, and operates over the -40°C to +115°C temperature range.
