Analog Devices Inc. AD9389BBCPZ-80

Overview

AD9389BBCPZ-80 from Analog Devices is a high-performance HDMI 1.3/DVI 1.0 transmitter IC with integrated HDCP 1.2 key storage, supporting up to 165 MHz pixel clock for 1080p and UXGA (1600 × 1200 @ 60 Hz) video formats, 8-channel I2S or S/PDIF audio up to 192 kHz, and single 1.8 V supply operation in a 64-lead LFCSP package - deployed in A/V receivers and HDMI repeaters.

For engineers reviewing the AD9389BBCPZ-80 datasheet, AD9389BBCPZ-80 pinout, AD9389BBCPZ-80 application, or AD9389BBCPZ-80 equivalent, this page delivers verified electrical parameters, TMDS channel mapping, HDCP subsystem integration details, thermal resistance (θJA = 59°C/W), and real-world design constraints including EXT_SWG resistor tolerance (±1%) and 5 V–tolerant DDC pins.

Technical Context

The AD9389BBCPZ-80 implements three TMDS differential data channels (Tx0±/Tx1±/Tx2±) and one TMDS clock channel (TxC±), all operating at 10× pixel rate with 800–1200 mV differential swing and <490 ps transition times. Its on-chip MPU handles HDCP authentication and EDID reads via dual I²C interfaces: 5 V–tolerant DDC bus (DDCSCL/DDCSDA) and 1.8–3.3 V internal control (SCL/SDA).

Video input supports RGB/YCbCr/DDR formats with automatic CEA-861B timing detection; audio accepts 16–24-bit I2S (up to 8 ch @ 192 kHz) or S/PDIF stereo/compressed streams without external MCLK. Power architecture separates AVDD (TMDS outputs), DVDD (digital logic/I/O), and ultra-low-noise PVDD (PLL), each requiring dedicated bypassing per layout guidelines.

FAQ

What video resolutions does the AD9389BBCPZ-80 support?

The AD9389BBCPZ-80 supports all CEA-861B video formats up to 1080p60 and computer graphics resolutions up to UXGA (1600 × 1200 @ 60 Hz) at its maximum 165 MHz pixel clock. It automatically detects input timing and supports RGB, YCbCr, and DDR input formats - confirmed in the Rev. A datasheet General Description and Specifications tables.

Does the AD9389BBCPZ-80 require an external HDCP key storage device?

No. The AD9389BBCPZ-80 includes internal key storage for HDCP 1.2, eliminating the need for an external EEPROM or flash memory. This is explicitly stated in the FEATURES section and GENERAL DESCRIPTION of the Rev. A datasheet, and verified in the Pin Function Descriptions for MDA/MCL pins used for on-chip key access.

What are the power supply requirements for the AD9389BBCPZ-80?

The AD9389BBCPZ-80 operates from a single 1.8 V supply (1.71–1.89 V), but requires three isolated power domains: AVDD for TMDS outputs, DVDD for digital logic/I/O, and PVDD for the PLL. Each domain must be independently bypassed with 0.1 µF capacitors placed within 0.5 cm of respective pins - per PCB Layout Recommendations in the Rev. A datasheet.

Can the AD9389BBCPZ-80 accept 3.3 V logic inputs?

Yes. All digital inputs - including D[23:0], CLK, DE, HSYNC, VSYNC, HPD, S/PDIF, I2S[3:0], SCLK, LRCLK, and PD/A0 - accept CMOS logic levels from 1.8 V to 3.3 V, as specified in the DIGITAL INPUTS section of the Rev. A datasheet. HPD and DDC pins are additionally 5 V tolerant.

What is the purpose of the EXT_SWG pin on the AD9389BBCPZ-80?

The EXT_SWG pin on the AD9389BBCPZ-80 sets the internal reference current that determines TMDS output voltage swing. It must be connected to ground via an 887 Ω ±1% resistor - a requirement detailed in the Pin Function Descriptions and APPLICATIONS INFORMATION sections of the Rev. A datasheet. Deviation beyond ±1% tolerance risks noncompliance with HDMI differential swing specifications.
