MAX3814CHJ+T

Specialized Overview

The MAX3814CHJ+T is a TMDS equalizer and driver IC designed for DVI/HDMI applications. It compensates for FR-4 board microstrip and cable high-frequency losses up to 15dB at 825MHz, supporting data rates from 0.25Gbps to 1.65Gbps. The device features four independent channels with CML inputs and outputs, operating on a 3.3V supply with a typical current of 110mA. It provides selectable output currents (10mA or 15mA) via the LEVEL pin to accommodate back termination requirements. Residual jitter is less than 0.2UI P-P at 1.65Gbps. The component is housed in a 32-pin TQFP package.

Specialized Feature Summary

• Compensates for high-frequency attenuation in FR-4 traces and copper cables to extend signal reach.
• Provides fully compliant DVI/HDMI TMDS output signals with adjustable drive strength.
• Includes an enable pin to select between normal operation and power-down mode.

Specialized Applications

• Laptop PC TMDS Equalizer and Driver
• Docking Station TMDS Equalizer and Driver
• Cable TMDS Equalizer

Specialized Procurement Notes

Verify the specific suffix 'T' against official documentation, as standard listings may indicate tray packaging while tape-and-reel availability varies by distributor. Confirm RoHS compliance status and check for End-of-Life notifications prior to finalizing procurement plans.

Specialized Selection Notes

Select this component when designing systems requiring equalization for FR-4 or cable losses up to 15dB at 825MHz. Ensure the design supports a 3.3V supply and accommodates the 32-pin TQFP footprint. Verify that the application requires support for data rates up to 1.65Gbps.

Specialized FAQ

How does the LEVEL pin affect the output?

The LEVEL pin selects the output current level. A low state sets the current to 10mA for standard operation, while a high state increases it to 15mA to support 200Ω back termination resistors.

What is the maximum channel loss the MAX3814 can compensate for?

The device can compensate for channel losses up to 15dB at 825MHz, covering both FR-4 microstrip and cable attenuation.
