Analog Devices Inc. ADV3003ACPZ

Overview

ADV3003ACPZ from Analog Devices is a 4-channel HDMI/DVI TMDS equalizer and pre-emphasized driver IC designed for signal integrity restoration in high-speed video links. It supports data rates up to 2.25 Gbps, provides 12 dB fixed input equalization and selectable 6 dB output pre-emphasis, and features on-chip 50 Ω terminations for both inputs and outputs. It enables 1080p deep color (12-bit) HDMI formats and is used in front-panel HDMI extenders and multi-input display systems.

For engineers reviewing the ADV3003ACPZ datasheet, ADV3003ACPZ pinout, ADV3003ACPZ application, or ADV3003ACPZ equivalent, key selection considerations include input cable compensation capability (≥20 m at 2.25 Gbps), output pre-emphasis control (0 dB/6 dB), deterministic jitter performance (<25 ps p-p), thermal management via exposed paddle (ePAD), and compliance with HDMI 1.3 receive specifications.

Technical Context

The ADV3003ACPZ implements a fixed 12 dB high-frequency boost on all four TMDS input channels to compensate for insertion loss in long HDMI cables, with no programmability-equalization is always active when TX_EN = 1. Its input termination resistors are disabled when TX_EN = 0, presenting high-impedance to upstream sources to indicate link inactivity.

Output pre-emphasis is controlled by the PE_EN pin (0 dB or 6 dB), targeting high-loss PCB traces or output cables; it operates independently of equalization and does not affect input channel behavior. The device uses fully buffered unidirectional architecture with matched 50 Ω single-ended on-chip terminations referenced to VTTI (inputs) and VTTO (outputs), ensuring full-swing recovery and reflection suppression.

Key Specifications

Pinout & Package

The ADV3003ACPZ is housed in a 40-lead, 6 mm × 6 mm, RoHS-compliant LFCSP package with an exposed paddle (ePAD) that must be connected to AVEE (0 V) for thermal and electrical compliance.

FAQ

What is the maximum HDMI data rate supported by the ADV3003ACPZ?

The ADV3003ACPZ supports a maximum data rate of 2.25 Gbps per TMDS channel, enabling full compliance with HDMI 1.3 specifications including 1080p resolution with 12-bit deep color. This rating is validated across the full −40°C to +85°C operating temperature range and confirmed in Table 1 of the Rev. B datasheet under "Maximum Data Rate (DR) per Channel".

Does the ADV3003ACPZ require external termination resistors?

No, the ADV3003ACPZ integrates matched 50 Ω single-ended terminations on-chip for both inputs and outputs, eliminating the need for external 100 Ω differential termination networks. These terminations are referenced to VTTI (input) and VTTO (output), both typically tied to AVCC (3.3 V), and are automatically enabled when TX_EN is asserted high.

How does the TX_EN pin affect input termination behavior in the ADV3003ACPZ?

When TX_EN is driven low, the ADV3003ACPZ disables both its high-speed outputs and its on-chip input termination resistors, presenting a high-impedance state at IN[3:0]/IP[3:0]. This behavior informs upstream HDMI sources that the link is inactive, satisfying HDMI 1.3 hot-plug detection semantics and reducing system-level power consumption.

Can the ADV3003ACPZ be used with DVI-only systems?

Yes, the ADV3003ACPZ is explicitly designed for dual HDMI/DVI compatibility and meets DVI Version 1.0 transmitter eye diagram mask requirements. Its 4-channel TMDS architecture, 25 MHz–225 MHz pixel clock support, and 250 Mbps–2.25 Gbps data rate range align directly with DVI's operational envelope, including UXGA (1600×1200) and higher resolutions.

What is the role of the exposed paddle (ePAD) on the ADV3003ACPZ package?

The ePAD on the ADV3003ACPZ must be electrically and thermally connected to the AVEE (0 V) ground plane. It serves dual functions: lowering junction-to-board thermal resistance (θJC = 2.6°C/W) to maintain safe operation under full-load conditions, and providing a low-inductance return path critical for high-speed signal integrity and EMI control in HDMI/DVI applications.
