MAX9249GCM/V+

The MAX9249GCM/V+ is a gigabit multimedia serial link serializer with LVDS system interface in 48 pin TQFP package. The MAX9249 serializer with LVDS system interface utilizes Gigabit multimedia serial link (GMSL) technology. The 3-channel mode handles three lanes of LVDS data (21bits), UART control signals and three audio signals. The 4-channel mode handles four lanes of LVDS data (28bits), UART control signals, three audio signals and/or up to three auxiliary parallel inputs. The 3 audio inputs form a standard I2S interface, supporting sample rates from 8kHz to 192kHz and audio word lengths of 4 to 32bits. The embedded control channel forms a full-duplex, differential, 100kbps to 1Mbps UART link between the serializer and deserializer. The electronic control unit (ECU) or microcontroller can be located on the MAX9249 side of the link on deserializer side of the link (typical for image sensing) or on both sides. Complies with ISO 10605 and IEC 61000-4-2 ESD protection.
