Overview
The MAX96752FGTN/V+ is a GMSL2 (Gigabit Multimedia Serial Link 2) deserializer produced by Analog Devices Inc./Maxim Integrated. This device is designed to convert single- or dual-link GMSL serial input into single or dual OLDI (OpenLDI) output, enabling the transmission of video and bidirectional data over a single wire. It supports various configurations, including single-port (4 or 8 lanes) and dual-port (2 x 4 lanes) OLDI output, making it versatile for driving displays with different resolutions. The device operates over an automotive temperature range of -40°C to +105°C and is AEC-Q100 qualified, ensuring reliability in harsh environments.
