Analog Devices Inc. ADV7623BSTZ-P-RL

Overview

ADV7623BSTZ-P-RL from Analog Devices is a 4-input, 1-output HDMI transceiver IC integrating HDCP 1.4 repeater functionality, Xpressview™ fast port switching (<1 s), and support for 225 MHz TMDS clock rates enabling 1080p 36-bit Deep Color. It features quad HDMI receivers with adaptive equalization (up to 30 m cable), integrated EDID RAM (512 bytes/port), and dual-role audio I/O supporting S/PDIF, DSD, and HBR formats including Dolby TrueHD and DTS-HD Master Audio. It serves as the core HDMI routing and content protection engine in AV receivers and sound bars.

For engineers reviewing the ADV7623BSTZ-P-RL datasheet, ADV7623BSTZ-P-RL pinout, ADV7623BSTZ-P-RL application, or ADV7623BSTZ-P-RL equivalent, key selection considerations include its 144-lead LQFP package, 5 V-tolerant DDC/HPD/CEC pins, ARC receiver capability, ultralow-jitter digital PLL (100% deskew), and support for HDMI 3D TV formats alongside legacy DVI RGB up to 1600 × 1200 @ 60 Hz.

Technical Context

The ADV7623BSTZ-P-RL implements a hardware-based HDCP engine that offloads repeater authentication and key management from host software, enabling sub-second Xpressview switching across four HDMI inputs. Its HDMI receiver subsystem includes per-port adaptive equalizers, hot-plug detection controllers, and 5 V detect inputs, while the transmitter integrates a dedicated TMDS serializer with programmable output swing control via EXT_SWING.

Audio processing is decoupled into parallel paths: a flexible 6-channel audio input/output port (AP0–AP5) supports I2S, left/right-justified, and PCM formats, and an independent ARC receiver extracts upstream audio over the HDMI link. The chip uses separate power domains-CVDD (1.8 V), DVDDIO (3.3 V), TXAVDD (1.8 V), and TVDD (3.3 V)-to isolate analog, digital core, I/O, and termination circuitry.

Key Specifications

Pinout & Package

ADV7623BSTZ-P-RL is housed in a 144-lead, 20 mm × 20 mm, Pb-free LQFP package with exposed thermal pad (not electrically connected). Pin 1 is located at top-left corner; pin numbering proceeds counterclockwise. Power, ground, and signal pins are distributed across all four sides to minimize crosstalk and support clean layout of high-speed TMDS traces.

FAQ

What is the maximum supported TMDS clock rate for ADV7623BSTZ-P-RL?

The ADV7623BSTZ-P-RL supports a maximum TMDS clock rate of 225 MHz, enabling transmission of 1080p video with 36-bit Deep Color, all mandatory HDMI 3D formats, and DVI RGB up to 1600 × 1200 at 60 Hz. This specification is guaranteed across the full industrial temperature range (0°C to 70°C) and validated per the Rev. D datasheet AC timing table.

Does ADV7623BSTZ-P-RL support HDCP 2.2 or only HDCP 1.4?

The ADV7623BSTZ-P-RL implements HDCP 1.4 with full repeater compliance, including authenticated key exchange, revocation checking, and encrypted retransmission. It does not support HDCP 2.2; that capability is found in later-generation Analog Devices parts such as the ADV7619. For new designs requiring HDCP 2.2, ADV7623BSTZ-P-RL is not suitable.

How many audio channels can ADV7623BSTZ-P-RL process simultaneously?

The ADV7623BSTZ-P-RL supports simultaneous operation of six independent audio input ports (AP0_IN through AP5_IN) and six output ports (AP0_OUT through AP5_OUT), each configurable for I²S, left/right-justified, or PCM formats. It also handles S/PDIF, DSD, and HBR audio streams-including Dolby TrueHD and DTS-HD Master Audio-via dedicated hardware paths.

What is the function of the EXT_SWING pin on ADV7623BSTZ-P-RL?

The EXT_SWING pin on ADV7623BSTZ-P-RL sets internal reference currents for the TMDS output drivers. A precision 887 Ω resistor (1% tolerance) must be connected between EXT_SWING and ground to configure nominal 1000 mV differential output swing. Deviation from this value alters output amplitude and may impact signal integrity or HDMI compliance testing margins.

Is ADV7623BSTZ-P-RL pin-compatible with other devices in the ADV76xx family?

No, ADV7623BSTZ-P-RL is not pin-compatible with other ADV76xx devices. Its 144-lead LQFP footprint, pin assignment (e.g., dedicated ARC+ and HPD_ARC− inputs), and power domain distribution (eight distinct supply rails) are unique to the ADV7623. Migration to alternate parts like ADV7611 or ADV7619 requires PCB redesign and firmware adaptation.
