MAX9268GCM/V+

Serializers, Deserializers Overview

The MAX9268GCM/V+ is a Gigabit Multimedia Serial Link (GMSL) deserializer featuring an LVDS system interface. It supports a maximum serial payload data rate of 2.5Gbps over shielded twisted-pair cables up to 15m in length. The device operates with a core supply voltage of 3.3V and an I/O supply range of 1.7V to 3.6V. It provides output clock rates up to 104MHz in 3-channel mode or 78MHz in 4-channel mode, supporting display resolutions from QVGA to WXGA with 24-bit color. The component includes an embedded bidirectional control channel operating between 100kbps and 1Mbps, and an I2S audio interface supporting sample rates from 8kHz to 192kHz. It is housed in a 48-pin TQFP package with an exposed pad and is qualified for automotive applications within a temperature range of -40°C to +105°C.

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix when sourcing components. The 'V' suffix indicates automotive qualification, while the '+' suffix denotes lead-free and RoHS compliance. Confirm that the package type matches the required footprint, specifically the 48-lead TQFP with an exposed thermal pad. Ensure compatibility with existing design constraints regarding the exposed pad connection to analog ground for proper thermal dissipation and electrical performance.

Serializers, Deserializers Selection Notes

Select this component when a robust GMSL deserialization solution is required for automotive environments. It is suitable for designs needing flexible LVDS output configurations via the BWS pin. Consider the integrated equalizer and serializer preemphasis synergy for extended cable lengths. Verify that the target application benefits from the built-in I2C master functionality for remote peripheral control without requiring additional interface logic.

Serializers, Deserializers Part Context

This part belongs to the Maxim Integrated GMSL family of serializers and deserializers. It is designed to operate in tandem with compatible GMSL serializers to transmit multimedia data over single coaxial or twisted-pair cables. The device addresses the need for reduced pin counts and smaller package sizes in automotive infotainment and navigation systems by consolidating video, audio, and control signals into a single serial link.

Serializers, Deserializers FAQ

How does the MAX9268 handle device addressing?

The MAX9268 utilizes two three-level inputs, ADD0 and ADD1, to select its device address. These inputs latch their state upon power-up or when resuming from power-down mode, allowing for the selection of nine distinct device addresses.

What is the function of the BWS pin?

The BWS (Bus-Width Select) pin determines the output width configuration. Setting BWS low selects 3-channel mode, while setting it high selects 4-channel mode, which affects the number of LVDS data lanes and control outputs available.

Can the MAX9268 control peripherals on the remote serializer side?

Yes, the embedded control channel allows an electronic control unit or microcontroller located on the MAX9268 side to control peripherals on the remote serializer side, such as touch screens, camera modules, and backlight controllers, using I2C or GMSL UART formats.
