ADV7520NKBBCZ-80

Overview

The ADV7520NKBBCZ-80 is a low-power HDMI/DVI transmitter supporting HDMI v1.3 and DVI v1.0 standards with HDCP 1.3 compliance. It operates at an 80 MHz clock frequency, enabling HDTV resolutions up to 720p and 1080i, alongside computer graphics up to XGA (1024 × 768 @ 75 Hz). The device integrates a CEC controller and buffer, reducing system overhead. It accepts digital video inputs from 1.8 V to 3.3 V logic levels and supports audio formats including S/PDIF and 8-channel I2S up to 192 kHz. Powered by a single 1.8 V supply, it features 5 V tolerant I2C and HPD I/Os.

Feature Summary

• Integrates a CEC controller and buffer to reduce system design complexity and component count.
• Includes an on-chip microprocessor for automated HDCP operations and EDID reading via an I2C master interface.
• Features a programmable 2-way color space converter supporting RGB, YCbCr, and DDR formats.
• Provides 5 V tolerance on I2C and Hot Plug Detect pins, eliminating the need for external voltage translation devices.

Applications

• Digital video cameras
• Personal media players
• DVD players and recorders
• HDMI repeater/splitter

Procurement Notes

Verify that the specific part number suffix matches the required packaging configuration, as the datasheet lists both bulk and reel options for this model. Confirm the operating temperature range aligns with the -25°C to +90°C specification provided in the ordering guide. Ensure compatibility with the 76-ball CSP_BGA footprint during PCB layout planning. Cross-reference the RoHS compliance status indicated by the 'Z' suffix against current environmental regulations.

Selection Notes

Select this component for portable applications requiring low power consumption and integrated CEC functionality. It is suitable for designs needing direct connection to 5 V tolerant buses without additional level shifters. Consider its support for high-definition audio formats if surround sound transmission is required. Evaluate the 80 MHz bandwidth limit against the maximum resolution requirements of the target display system.

Part Context

This transmitter belongs to Analog Devices' HDMI solution portfolio, designed to facilitate high-definition multimedia transmission. It complements other signal chain components by handling digital-to-HDMI conversion with built-in content protection. The integration of video capture and audio data modules simplifies the overall architecture for mobile multimedia devices.

Replacement Considerations

Check for availability of the ADV7520NK/PCBZ evaluation board for prototyping purposes. Verify if alternative package options within the same family meet mechanical constraints.
