ADV7611BSWZ-P Description

The ADV7611BSWZ-P is a single-input HDMI receiver for automotive, industrial, and professional applications. It supports HDMI 1.4a features, including all mandatory 3D TV formats, and handles video resolutions up to UXGA 60 Hz at 8-bit color depth. The device integrates a CEC controller for capability discovery and control (CDC). Its audio extraction capabilities are versatile, supporting I2S, S/PDIF, and DST audio streams, while an advanced mute controller eliminates unwanted noise in the audio output.

Fabricated using advanced CMOS technology, the ADV7611BSWZ-P features a compact 10 mm × 10 mm, 64-lead LQFP_EP surface-mount package that is RoHS-compliant and operates across a wide industrial temperature range of −40°C to +85°C. A central component processor handles video signal processing, offering features such as contrast, brightness, and saturation adjustments, STDI detection, free run, and synchronization alignment controls.

ADV7611BSWZ-P Working Principle

The core function of the ADV7611BSWZ-P is to accurately convert HDMI signals output by high-definition devices into digital image formats recognizable by display processors or main control chips. During operation, its integrated HDMI receiver first decodes and denoises high-speed differential signals, and automatically handles the HDCP content protection protocol.

It features a built-in EDID (Extended Display Identification Data) memory that actively communicates with the source device. The processed video signal is then output to a downstream FPGA or video processor via a 24-bit parallel CMOS interface or equivalent bus. With its low-power design and compact form factor, it is ideal for automotive displays, surveillance screens, and portable projectors.

ADV7611BSWZ-P vs. ADV7611BSWZ-P-RL

ADV7611BSWZ-P and ADV7611BSWZ-P-RL are identical in chip performance, specifications, package size, and electrical characteristics. The only difference lies in the packaging method:

Packaging Type

l  ADV7611BSWZ-P (Tray): Chips are neatly arranged in an anti-static tray, suitable for small-batch sample development, manual soldering, or repair applications.

l  ADV7611BSWZ-P-RL (Reel/Tape & Reel): Chips are embedded in a continuous plastic tape and wound on a reel, designed for large-scale automated production (SMT) and can be directly loaded into pick-and-place feeders for high-speed mechanical handling.

Selection Recommendations

l  Small-batch or repair use: Tray (-P) is more flexible, and many suppliers support individual sales.

l  Mass production: Reel (-RL) is preferred, compatible with automated production lines, and better protects pins during transport and high-speed assembly.

Suffix Explanation

l  BSWZ: LQFP package, RoHS-compliant, lead-free.

l  -P: Supports HDCP keys, ensuring compatibility with copyright-protected HDMI content.
