MAX9249GCM/V+

Serializers, Deserializers Overview

The MAX9249GCM/V+ is an automotive-grade serializer utilizing Gigabit Multimedia Serial Link (GMSL) technology. It supports a maximum serial payload data rate of 2.5Gbps over 15m shielded twisted-pair cables. The device accepts LVDS inputs at clock rates up to 104MHz in 3-channel mode or 78MHz in 4-channel mode, supporting resolutions up to WXGA with 24-bit color. It integrates I2S audio processing for sample rates from 8kHz to 192kHz and includes a bidirectional control channel operating between 100kbps and 1Mbps. Power supplies include 1.8V core, 1.8V to 3.3V I/O, and 3.3V LVDS. It operates within -40°C to +105°C.
