AD9387NKBBCZ-80

Overview

The AD9387NKBBCZ-80 is an HDMI v.1.3 transmitter fabricated in CMOS, operating at a clock frequency of up to 80 MHz. It supports HDTV resolutions including 480i through 1080i and computer graphics up to XGA (1024 × 768 @ 75 Hz). The device utilizes a single 1.8 V power supply with 5 V tolerant I/Os for I2C and HPD pins. Audio capabilities include S/PDIF and 8-channel uncompressed LPCM I2S supporting sample rates up to 192 kHz. It integrates an on-chip microprocessor for HDCP 1.3 operations and EDID reading.

Feature Summary

• Integrates an on-chip microprocessor to execute HDCP 1.3 encryption protocols and manage Extended Display Identification Data (EDID) reading via an I2C master interface.
• Supports dual digital audio input formats, enabling transmission of standard S/PDIF stereo or compressed audio alongside 8-channel uncompressed LPCM I2S surround sound.
• Features automatic input video format timing detection compliant with CEA-861D standards and includes a programmable color space converter for RGB and YCbCr signals.
• Designed for low-power portable applications by utilizing a single 1.8 V supply while maintaining 5 V tolerance on control pins to simplify system interconnects.

Applications

• Digital video cameras
• Personal media players
• HDMI repeater/splitter systems
• Digital set-top boxes

Procurement Notes

Verify the specific suffix -80 indicates the 80 MHz operational variant when sourcing. Confirm RoHS compliance status marked by the Z suffix. Ensure the 76-ball CSP_BGA package option BC-76-1 matches the target PCB footprint requirements. Cross-reference the thermal resistance specifications against the final enclosure design constraints.

Selection Notes

Select this component for designs requiring integrated HDCP 1.3 handling without external security controllers. The single 1.8 V supply requirement suits battery-operated portable electronics. Verify that the host processor can interface with the internal MPU registers for configuration. Consider the 76-ball BGA package size relative to available board real estate.

Part Context

This transmitter belongs to Analog Devices' high-definition multimedia interface product line, designed to bridge digital video sources to display devices.
