Analog Devices Inc. ADV7520NKBBCZ-80

Overview

ADV7520NKBBCZ-80 from Analog Devices is a low-power HDMI/DVI transmitter IC with integrated CEC controller, HDCP 1.3 encryption, and 80 MHz TMDS clock support for 720p/1080i HDTV and XGA (1024×768@75 Hz) graphics. It operates from a single 1.8 V supply, accepts 1.8 V–3.3 V logic inputs, and supports both 8-channel I2S and S/PDIF audio up to 192 kHz in portable digital video systems.

For engineers reviewing the ADV7520NKBBCZ-80 datasheet, ADV7520NKBBCZ-80 pinout, ADV7520NKBBCZ-80 application, or ADV7520NKBBCZ-80 equivalent, key selection considerations include HDMI v1.3 compliance, embedded CEC buffer capability, 76-ball CSP_BGA package thermal performance (θJA = 59°C/W), xvYCC color space support, and integrated I²C master for EDID/HDCP operations.

Technical Context

The ADV7520NKBBCZ-80 implements a full HDMI v1.3 transmitter core with HDCP 1.3 encryption engine and on-chip microcontroller for autonomous HDCP authentication and EDID readback via I²C master. Its TMDS output supports differential swing of 900–1100 mV with 48–52% duty cycle at 80 MHz.

It integrates dual audio interfaces-8-channel I2S (LRCLK/SCLK/I2S[3:0]) and S/PDIF-with no external MCLK required, and features automatic CEA-861D video timing detection, programmable RGB/YCbCr/DDR color space conversion, and ITU-R BT.656 embedded sync support.

Key Specifications

Pinout & Package

ADV7520NKBBCZ-80 is housed in a 76-ball Chip Scale Package Ball Grid Array (CSP_BGA), designated BC-76-1, measuring 6 mm × 6 mm × 1.4 mm, with JEDEC MO-225 compliance (excluding height). The package is RoHS-compliant and rated for −25°C to +90°C ambient operation.

FAQ

What video resolutions does the ADV7520NKBBCZ-80 support?

The ADV7520NKBBCZ-80 supports all HDTV resolutions up to 720p and 1080i, plus computer graphics up to XGA (1024 × 768 @ 75 Hz), enabled by its 80 MHz TMDS clock. It complies with HDMI v1.3 and DVI v1.0 standards, and supports CEA-861D timing detection for automatic format recognition. The ADV7520NKBBCZ-80 does not support 1080p60 or higher pixel rates.

Does the ADV7520NKBBCZ-80 require an external HDCP key or license?

No, the ADV7520NKBBCZ-80 includes an on-chip HDCP 1.3 encryption engine with embedded keys, eliminating the need for external key storage or licensing modules. Authentication is handled autonomously by the integrated microcontroller via I²C master-driven DDC communication. The ADV7520NKBBCZ-80 meets Digital Content Protection LLC requirements for secure content transmission without additional HDCP co-processors.

Can the ADV7520NKBBCZ-80 operate from a 3.3 V supply?

No, the ADV7520NKBBCZ-80 is specified for single 1.8 V core supply operation. While its digital I/Os (I²C, HPD, CEC) are 5 V tolerant, the core logic and TMDS transmitter require 1.8 V ±10%. Using 3.3 V will damage the ADV7520NKBBCZ-80. Input video/audio signals may swing between 1.8 V and 3.3 V, but power rails must remain at 1.8 V.

What audio formats does the ADV7520NKBBCZ-80 support over HDMI?

The ADV7520NKBBCZ-80 supports uncompressed 8-channel LPCM audio via I2S (up to 192 kHz) and stereo compressed audio (Dolby Digital, DTS) via S/PDIF, both embedded into the HDMI stream. It does not support HDMI Audio Return Channel (ARC) or eARC. The ADV7520NKBBCZ-80 requires no external MCLK for either interface, simplifying clock tree design in portable systems.

Is the ADV7520NKBBCZ-80 pin-compatible with other Analog Devices HDMI transmitters?

No, the ADV7520NKBBCZ-80 uses a proprietary 76-ball CSP_BGA (BC-76-1) footprint and is not pin-compatible with other Analog Devices HDMI transmitters such as the ADV7511 or ADV7513, which use different ball counts and signal assignments. PCB layout must be designed specifically for the ADV7520NKBBCZ-80 package; migration requires redesign of the HDI routing and power delivery network.
