Analog Devices / Maxim Integrated MAX9272A 28-Bit GMSL Deserializer

Analog Devices Inc. MAX9272A 28-Bit Compact Deserializer is designed to interface with a GMSL serializer over 50Ω coax or 100Ω shielded twisted-pair (STP) cable. This ADI device is ideal for automotive camera system applications and pairs with MAX9271 or MAX9273 serializers. The parallel output is programmable for single or double output. ADI MAX9272A GMSL Deserializer features an embedded control channel that operates from 9.6kbps to 1Mbps. Using the control channel, a microcontroller can program the serializer/deserializer and peripheral device registers at any time, independent of video timing. Two programmable GPIO ports and a continuously sampled GPI input are available.

For use with longer cables, the device has a programmable equalizer. Programmable spread spectrum is available on the parallel output. The serial input 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.
