Product details
Overview
AD9889KSTZ-80 from Analog Devices is an HDMI 1.1/DVI transmitter IC with integrated HDCP 1.1 encryption, supporting up to 80 MHz pixel clock for 1080i/720p video and 8-channel I2S or S/PDIF audio up to 192 kHz. It operates from a single 1.8 V supply, features 3.3 V-tolerant video/audio inputs, and delivers TMDS differential outputs compliant with HDMI physical layer requirements. Used in digital set-top boxes and AV receivers for secure high-definition content transmission.
For engineers reviewing the AD9889KSTZ-80 datasheet, AD9889KSTZ-80 pinout, AD9889KSTZ-80 application, or AD9889KSTZ-80 equivalent, key selection criteria include HDMI 1.1 compliance, HDCP 1.1 support, 80 MHz video bandwidth, dual-audio interface capability (I2S + S/PDIF), and LQFP-80 package compatibility with industrial temperature range (0°C to 70°C).
Technical Context
The AD9889KSTZ-80 implements a full HDMI 1.1 transmitter core with embedded HDCP cipher engine and on-chip I2C master for EDID reading. Its video path supports auto-detection of 34 EIA/CEA-861B formats and programmable 4:2:2 ↔ 4:4:4 color space conversion using pixel repetition or linear interpolation.
Audio handling includes parallel 8-channel I2S (up to 192 kHz) and S/PDIF input with no external master clock required. The device integrates three independent I2C buses: one slave for configuration, one master to read receiver EDID at 0xA0, and one master to access HDCP keys at 0xA0 - all with 5 V tolerant I/Os.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TFP401APZPR | No integrated HDCP; requires external EEPROM and key management; supports only DVI (no HDMI audio packetization) | Limited to non-protected digital video links; unsuitable for consumer HDMI content distribution | Select when HDCP is unnecessary and cost sensitivity outweighs feature completeness |
| Maxim MAX9516ETL+ | Lower 65 MHz bandwidth; supports only 720p/1080i video; no S/PDIF interface; I2S only up to 96 kHz | Targeted at entry-level portable displays and automotive infotainment with reduced resolution requirements | Choose for space-constrained designs where 80 MHz bandwidth and dual-audio support are not required |
Compared with TFP401APZPR and MAX9516ETL+, the AD9889KSTZ-80 uniquely combines HDMI 1.1 compliance, on-chip HDCP 1.1, 80 MHz bandwidth, and dual-audio interface - making it the only option among the three suitable for full-featured consumer AV equipment requiring secure high-definition transmission.

FAQ
What video formats does the AD9889KSTZ-80 support?
The AD9889KSTZ-80 supports all EIA/CEA-861B-defined formats up to 1080i and 720p, including 480i, 576i, 480p, 576p, 720p, and 1080i. It also handles graphic resolutions such as XGA (1024×768@75 Hz). Input flexibility covers RGB, YCbCr 4:4:4, YCbCr 4:2:2 (ITU-R BT.656 and separate sync), and DDR variants - all auto-detected and reported via registers R0x3E and R0x3F in the AD9889KSTZ-80.
Does the AD9889KSTZ-80 require an external HDCP key storage device?
No. The AD9889KSTZ-80 integrates a dedicated I2C master interface (MDA/MCL pins) that communicates directly with an external EEPROM containing HDCP keys at address 0xA0. While the keys reside externally, the AD9889KSTZ-80 performs all cryptographic operations internally - eliminating need for separate security ICs or host MCU involvement in HDCP authentication.
Can the AD9889KSTZ-80 operate with only S/PDIF audio input, without I2S?
Yes. The AD9889KSTZ-80 fully supports standalone S/PDIF audio input at sample rates up to 192 kHz, carrying stereo LPCM or compressed formats (Dolby Digital, DTS, THX). No MCLK is required for S/PDIF operation, and the device automatically extracts bit clock and word clock - enabling simplified audio subsystem design when I2S is not used in the AD9889KSTZ-80 implementation.
What is the function of the EXT_SW pin on the AD9889KSTZ-80?
The EXT_SW pin on the AD9889KSTZ-80 sets TMDS differential output voltage swing by connecting an 887 Ω ±1% resistor to ground. This allows precise adjustment of output amplitude (800–1200 mV) to match cable length, connector losses, and sink input sensitivity - ensuring HDMI compliance and signal integrity without requiring external termination or calibration firmware in the AD9889KSTZ-80 system.
Is the AD9889KSTZ-80 pin-compatible with other members of the AD9889 family?
Yes. The AD9889KSTZ-80 shares identical pinout, package (80-lead LQFP), and register map with other speed-grade variants including AD9889KSTZ-100 and AD9889KSTZ-165. Differences are limited to maximum supported pixel clock (80 MHz vs. 100/165 MHz) and corresponding AC timing specifications - allowing drop-in replacement in designs where lower bandwidth suffices, without layout changes for the AD9889KSTZ-80.
