Product details
Overview
ADV7682WBSWZ-P from Analog Devices is an automotive-qualified APIX2 transmitter IC with dual HDMI receivers, HDCP 1.4 decryption on both ports, 3000 Mbps downstream link bandwidth, 187.5 Mbps upstream bandwidth, and integrated CEC 1.4 controller - used in rear-seat entertainment systems to route encrypted HD video/audio over coaxial cable to remote displays.
For engineers reviewing the ADV7682WBSWZ-P datasheet, ADV7682WBSWZ-P pinout, ADV7682WBSWZ-P application, or ADV7682WBSWZ-P equivalent, key selection considerations include dual-port HDCP repeater capability (up to 24 KSVs), ITU-R BT.656 8-bit interface support at 148.5 MHz for 720p, and sideband communication via MII/SPI/I²C/GPIO for automotive infotainment system integration.
Technical Context
The ADV7682WBSWZ-P implements a dual-channel APIX2 physical layer transmitter with independent encryption engines for video and audio streams, enabling daisy-chained display topologies. It integrates two full HDMI 1.4a receivers with HDCP 1.4 decryption, hardware-controlled repeater functions, and adaptive TMDS equalization for robust signal integrity across long cables.
Sideband communication uses MII, SPI, I²C, and GPIO interfaces to configure EDID, manage HDCP keys, and control CEC 1.4 messaging. The device supports synchronized dual audio streams via on-chip sample rate conversion and multiplexed TDM I²S I/O, with timing alignment to external master clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar APIX2 transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7680WBSWZ-P | Single HDMI input port; no dual-port HDCP decryption; same APIX2 transmitter and CEC functionality. | Suitable only for single-source RSE or head unit designs without dual HDMI aggregation. | Select when system requires only one HDMI input and lower BOM cost is prioritized over dual-source flexibility. |
| MAX96705GTJ+T | GMSL2 serializer with embedded HDCP 2.2; higher bandwidth (6 Gbps); different sideband protocol (GMSL vs. APIX2). | Targets next-gen automotive ADAS and cockpit displays requiring HDCP 2.2 and higher resolution support. | Choose for new designs needing HDCP 2.2 compliance, higher bandwidth, or GMSL2 ecosystem compatibility. |
Compared with ADV7682WBSWZ-P, ADV7680WBSWZ-P reduces feature set to single HDMI input but retains identical APIX2 link performance and automotive qualification, while MAX96705GTJ+T offers HDCP 2.2 and GMSL2 interoperability at the cost of APIX2 ecosystem lock-in and higher system-level integration effort.
