Product details
Overview
MAX3816ACUE+T from Maxim Integrated is an I²C/Display Data Channel (DDC) 2-wire extender IC designed for bidirectional signal integrity restoration in DVI, HDMI, and VGA video interfaces. It compensates for cable capacitance up to 3000pF (guaranteed), supports 100kbps operation over 60m cables, operates from 3.0V to 5.5V supply, and features slew-rate-limited rail-to-rail drivers with 2.5µs holdoff timing - deployed at the display side to restore DDC clock and data signals.
For engineers reviewing the MAX3816ACUE+T datasheet, MAX3816ACUE+T pinout, MAX3816ACUE+T application, or MAX3816ACUE+T equivalent, this page delivers verified technical context, real-world DDC extension constraints, parallel/series mode behavior, voltage translation capability between 5V cable and 3.3V display domains, and validated alternative options for DDC bus extension in commercial display systems.
Technical Context
The MAX3816ACUE+T implements dual independent controllers (CLOCK and DATA) with level-shifting, cable-side slew-rate-limited drivers, display-side open-drain drivers, and adaptive level-sensing circuitry referenced to GND_REF (cable side) and VSS (display side). Its state machine enforces a 2.5µs holdoff after each transition to suppress reflections and ensure stable wired-AND bus arbitration.
In series mode, it isolates source and display domains electrically - supporting 5V-to-3.3V DDC level translation and ground offset tolerance - while in parallel mode, it enables coexistence with other I²C speed-up devices on the same bus. Cable termination impedance (~60Ω) is active only during the first 1.75µs of driver assertion to absorb round-trip reflections from up to 60m cables.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar DDC/I²C extension applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3815ETE+ | TMDS® equalizer (not DDC extender); no DDC signal restoration capability; separate IC required for DDC path. | Used alongside MAX3816ACUE+T in complete video extension solutions - not a functional substitute. | Select MAX3816ACUE+T alone for DDC-only extension; pair with MAX3815ETE+ only when both TMDS and DDC extension are needed. |
| TI TCA9517A | I²C bus repeater with 1.8V–5.5V level shift; no cable capacitance compensation, no slew-rate control, no holdoff timing, max 1m cable support. | Limited to short-board or backplane I²C extension - cannot address DDC timing violations from >5m cables. | Choose TCA9517A only for intra-chassis I²C buffering; MAX3816ACUE+T remains required for certified DVI/HDMI cable extension. |
Compared with MAX3816ACUE+T, MAX3815ETE+ addresses TMDS signals only and requires pairing for full video link extension, while TCA9517A lacks cable-compensation architecture and fails to meet DDC timing specs beyond 1m - making MAX3816ACUE+T uniquely qualified for standards-compliant, long-cable DDC restoration.

FAQ
What is the primary function of the MAX3816ACUE+T in a DVI/HDMI system?
The MAX3816ACUE+T restores bidirectional DDC (Display Data Channel) signal integrity over long cables by compensating for excess capacitance, enforcing precise holdoff timing, and providing slew-rate-limited drivers. It operates exclusively on the DDC bus - not the TMDS video path - and is deployed at the display side to ensure reliable EDID communication and HDCP handshaking in MAX3816ACUE+T-based systems.
Does the MAX3816ACUE+T support level translation between 5V and 3.3V DDC domains?
Yes, the MAX3816ACUE+T supports voltage translation when configured in series mode: VCC is connected to the 5V cable-side DDC supply, and VDD is powered from the display's 3.3V rail. This configuration isolates ground offsets and enables compliant DDC signaling between 5V sources and 3.3V display logic - a key capability confirmed in the MAX3816ACUE+T datasheet Applications Information section.
Can the MAX3816ACUE+T be used in parallel with other I²C speed-up devices?
Yes, the MAX3816ACUE+T supports parallel mode (MODE = high) explicitly designed for interoperability with other I²C accelerators on the same DDC bus. In this mode, it tolerates noncompliant VIH/VOL levels from legacy sources/sinks and can be disabled via DRVR_EN to allow direct bus pass-through - functionality validated in Figure 7 and Applications Information of the MAX3816ACUE+T datasheet.
What is the maximum cable capacitance the MAX3816ACUE+T can compensate?
The MAX3816ACUE+T guarantees compensation for cable capacitance up to 3000pF - eight times the standard I²C specification - and typically extends beyond 5000pF. This performance is measured under full 100kbps DDC operation and is confirmed in the Electrical Characteristics table and Typical Operating Characteristics plots (e.g., toc08) of the MAX3816ACUE+T datasheet.
Is the MAX3816ACUE+T suitable for HDMI 2.0 or higher bandwidth applications?
The MAX3816ACUE+T is designed solely for DDC/I²C extension and does not process or condition TMDS, HDMI 2.0, or higher-speed video signals. Its specifications target DDC timing compliance (100kbps, 3000pF load) - fully compatible with HDMI 1.4, 2.0, and 2.1 source/display handshaking, but unrelated to TMDS data rate improvements. MAX3816ACUE+T remains valid for all HDMI versions relying on standard DDC.
