Analog Devices Inc. AD9889BBCPZ-165

Overview

AD9889BBCPZ-165 from Analog Devices is a 165 MHz HDMI v.1.3/DVI v.1.0 transmitter IC with integrated HDCP v.1.2 encryption, supporting 1080p/60 Hz and UXGA (1600 × 1200) video output, 8-channel I2S or S/PDIF audio up to 192 kHz, and single 1.8 V supply operation in a 64-lead LFCSP package. It serves as the core video/audio interface bridge in digital AV source devices.

For engineers reviewing the AD9889BBCPZ-165 datasheet, AD9889BBCPZ-165 pinout, AD9889BBCPZ-165 application, or AD9889BBCPZ-165 equivalent, key selection criteria include TMDS clock rate (165 MHz), HDCP compliance, 5 V-tolerant DDC/I2C pins, on-chip microcontroller for EDID/HDCP, and support for both embedded sync (ITU-R BT.656) and discrete HSYNC/VSYNC timing.

Technical Context

The AD9889BBCPZ-165 implements a full HDMI v.1.3 transmitter core with three TMDS data channels (Tx0–/+, Tx1–/+, Tx2–/+) and one TMDS clock channel (TxC–/+), all operating at 10× pixel clock rate up to 165 MHz. Its internal two-way color space converter supports RGB ↔ YCbCr conversion and 4:2:2 to 4:4:4 upsampling.

It integrates an I2C master for EDID reading and HDCP key management, plus an interrupt-driven on-chip microprocessor that reports hot-plug detection, HDCP authentication status, and video format changes. All digital I/Os accept 1.8 V–3.3 V logic, while DDCSDA/DDCSCL and HPD tolerate 5 V.

FAQ

What video resolutions does the AD9889BBCPZ-165 support?

The AD9889BBCPZ-165 supports all CEA-861B-defined formats up to 1080p/60 Hz and computer graphics resolutions up to UXGA (1600 × 1200 at 60 Hz) via its 165 MHz TMDS interface. It also handles 1080i, 720p, and lower resolutions including 480i/p. The device performs automatic input timing detection and adapts to incoming video format without host software intervention.

Does the AD9889BBCPZ-165 require an external HDCP key storage device?

Yes-the AD9889BBCPZ-165 requires an external EEPROM connected to its MCL/MDA pins to store the HDCP key. The on-chip microcontroller reads this key during authentication. The device does not embed keys internally; the EEPROM must be pre-programmed with valid HDCP keys licensed from Digital Content Protection, LLC.

Can the AD9889BBCPZ-165 operate with a 3.3 V logic interface?

No-the AD9889BBCPZ-165 digital I/Os (D[23:0], CLK, DE, etc.) accept 1.8 V–3.3 V CMOS logic levels, but its core supply is strictly 1.8 V ±5% (VDD = 1.71–1.89 V). Using 3.3 V on DVDD/AVDD/PVDD will damage the AD9889BBCPZ-165. Level translation is required only if driving from >3.3 V sources-not for standard 3.3 V FPGA/ASIC outputs.

How is the I2C address configured on the AD9889BBCPZ-165?

The I2C slave address of the AD9889BBCPZ-165 is set by the logic state of the PD/A0 pin at power-up: low = 0x72, high = 0x7A. This dual-function pin also controls power-down polarity. Address configuration is latched during initial power application and remains fixed until next power cycle-no runtime reconfiguration is supported.

What is the purpose of the EXT_SWG pin on the AD9889BBCPZ-165?

The EXT_SWG pin on the AD9889BBCPZ-165 sets internal reference currents for TMDS output driver strength. A precision 887 Ω (±1%) resistor must be connected between EXT_SWG and ground. Deviation beyond tolerance causes incorrect differential swing (800–1200 mV), risking HDMI compliance failure or signal integrity issues at 165 MHz.
