Analog Devices Inc./Maxim Integrated MAX9293GTN/V+

Overview

MAX9293GTN/V+ from Analog Devices is a 3.12Gbps GMSL serializer with HDCP content protection, converting HDMI 1.4a input to serialized video/audio/control over coax or STP cable up to 15m. It supports 104MHz pixel clock (1920×720p/60Hz), 192kHz/32-bit audio in TDM mode, and programmable 100–500mV SE / 100–400mV diff output amplitude for automotive infotainment and camera systems.

For engineers reviewing the MAX9293GTN/V+ datasheet, MAX9293GTN/V+ pinout, MAX9293GTN/V+ application, or MAX9293GTN/V+ equivalent, key selection considerations include HDCP support, GMSL coax/STP compatibility, HDMI input equalization, spread-spectrum EMI reduction, and -40°C to +105°C automotive qualification.

Technical Context

The MAX9293GTN/V+ implements a full GMSL serializer with integrated HDMI receiver front-end including DDC, HPD, EDID, and HVDD termination. Its embedded control channel operates at 9.6kbps–1Mbps in UART-to-UART, UART-to-I2C, or I2C-to-I2C modes, enabling real-time register access to local and remote devices independent of video timing.

HDCP 1.4 encryption is hardware-accelerated and fully managed via the control channel; authentication state transitions and repeater support are handled internally. The device features programmable pre/deemphasis, spread-spectrum modulation (with RXC_ tracking), and high-immunity reverse control-channel mode for noise-prone automotive environments.

FAQ

Does MAX9293GTN/V+ support HDCP, and how is it implemented?

Yes, MAX9293GTN/V+ integrates full HDCP 1.4 content protection hardware. Encryption is enabled via dedicated registers, synchronized with link startup, and supports repeater topologies. Unlike MAX9291, only MAX9293GTN/V+ provides this capability - it requires no external crypto controller and manages authentication handshake autonomously over the GMSL control channel.

What is the difference between MAX9293GTN/V+ and MAX9291?

MAX9293GTN/V+ adds hardware-based HDCP 1.4 encryption while sharing identical pinout, electrical specs, and functional behavior with MAX9291. Both support HDMI 1.4a input, 3.12Gbps GMSL serialization, coax/STP output, and identical register maps - the sole functional distinction is HDCP enablement in MAX9293GTN/V+.

Can MAX9293GTN/V+ drive standard FAKRA coax connectors?

Yes, MAX9293GTN/V+ is explicitly designed to drive 50Ω coax cable with FAKRA connectors. Its programmable single-ended output amplitude (100–500mV) and integrated pre/deemphasis allow reliable 15m transmission at full 3.12Gbps rate without external drivers or equalizers - validated per automotive EMC and signal integrity requirements.

What audio formats does MAX9293GTN/V+ support from HDMI input?

MAX9293GTN/V+ extracts L-PCM audio from HDMI sources in both stereo I2S and multichannel TDM formats. It supports sample rates from 32kHz to 192kHz and sample depths up to 32 bits, with configurable channel allocation (up to 8 channels) mapped directly from HDMI Audio InfoFrame metadata - no external audio processor required.

Is MAX9293GTN/V+ compatible with non-Analog Devices GMSL deserializers?

Yes, MAX9293GTN/V+ pairs with any GMSL deserializer supporting coax input. When configured for STP output, it maintains backward compatibility with legacy GMSL deserializers. Interoperability is ensured through standardized GMSL protocol framing, control channel command sets, and physical layer signaling - confirmed in Analog Devices' interoperability test reports.
