Analog Devices Inc. AD9387NKBBCZ-80

Overview

AD9387NKBBCZ-80 from Analog Devices is a high-performance, low-power HDMI/DVI transmitter IC supporting up to 80 MHz pixel clock, HDMI v1.3 and DVI v1.0 protocols, HDCP 1.3 encryption, and operation from −25°C to +90°C in a 76-ball CSP_BGA package. It processes RGB/YCbCr/DDR video formats and handles 8-channel I2S or S/PDIF audio up to 192 kHz for portable digital video applications.

For engineers reviewing the AD9387NKBBCZ-80 datasheet, AD9387NKBBCZ-80 pinout, AD9387NKBBCZ-80 application, or AD9387NKBBCZ-80 equivalent, key selection criteria include TMDS differential swing (900–1100 mV), 1.8 V single-supply operation, 5 V-tolerant I2C/HPD pins, integrated HDCP microcontroller, and CEA-861D auto-detection capability.

Technical Context

The AD9387NKBBCZ-80 implements a full HDMI v1.3 transmitter core with embedded HDCP 1.3 encryption engine and on-chip microprocessor for EDID read and HDCP handshake management. It accepts parallel 24-bit RGB/YCbCr video with embedded or separate syncs and supports ITU-R BT.656 timing.

Its audio subsystem simultaneously handles 8-channel I2S (up to 192 kHz) and S/PDIF stereo/compressed streams without requiring an external audio master clock. The device uses a single 1.8 V supply and features 5 V-tolerant I2C and HPD I/Os to eliminate level-shifting components.

FAQ

What video resolutions does the AD9387NKBBCZ-80 support?

The AD9387NKBBCZ-80 supports HDTV resolutions up to 1080i and 720p, plus computer graphics up to XGA (1024 × 768 @ 75 Hz), enabled by its 80 MHz pixel clock capability. It auto-detects input timing per CEA-861D and supports RGB, YCbCr, and DDR video formats with programmable color space conversion. These capabilities are confirmed in the General Description and Table 1 specifications of the AD9387NKBBCZ-80 datasheet Rev. 0.

Does the AD9387NKBBCZ-80 integrate HDCP functionality?

Yes, the AD9387NKBBCZ-80 integrates a dedicated on-chip microprocessor that performs full HDCP 1.3 encryption, key exchange, and authentication operations. This eliminates the need for external HDCP management logic and reduces host MCU firmware overhead. The feature is explicitly documented in the FEATURES and GENERAL DESCRIPTION sections of the AD9387NKBBCZ-80 datasheet Rev. 0.

What audio interfaces does the AD9387NKBBCZ-80 support?

The AD9387NKBBCZ-80 supports both 8-channel I2S audio (up to 192 kHz for 7.1 LPCM) and S/PDIF (stereo LPCM or compressed Dolby Digital/DTS). Notably, it requires no external audio master clock for either interface. This dual-path capability and clock independence are specified in the FEATURES and GENERAL DESCRIPTION sections of the AD9387NKBBCZ-80 datasheet Rev. 0.

What is the package type and thermal rating of the AD9387NKBBCZ-80?

The AD9387NKBBCZ-80 uses a 76-ball CSP_BGA (BC-76-1), 6 mm × 6 mm × 1.4 mm, RoHS-compliant package with θJA = 59°C/W and θJC = 15.2°C/W. Its operating temperature range is −25°C to +90°C, validated per the Ordering Guide and Thermal Characteristics table in the AD9387NKBBCZ-80 datasheet Rev. 0.

Is the AD9387NKBBCZ-80 compatible with 5 V logic interfaces?

Yes, the AD9387NKBBCZ-80 features 5 V-tolerant I2C (SCL/SDA) and HPD pins, allowing direct connection to 5 V host systems without external level shifters. This is explicitly stated in the FEATURES section and confirmed in the Absolute Maximum Ratings table of the AD9387NKBBCZ-80 datasheet Rev. 0.
