NXP Semiconductors TDA19989AET/C189,5

Overview

TDA19989AET/C189,5 from NXP Semiconductors is an HDMI 1.3a transmitter IC designed for mobile multimedia systems. It supports 150 MHz pixel rate, 3×8-bit RGB/YCbCr video input, S/PDIF or dual I²S audio up to 192 kHz, HDCP 1.3 encryption, and CEC control - all in a 4.5×4.5 mm TFBGA64 package optimized for battery-powered devices like digital cameras and portable media players.

For engineers reviewing the TDA19989AET/C189,5 datasheet, TDA19989AET/C189,5 pinout, TDA19989AET/C189,5 application, or TDA19989AET/C189,5 equivalent, key selection considerations include its low-power standby/sleep modes, programmable input formatter for ITU656/YCbCr 4:2:2/RGB 4:4:4, integrated DDC-bus master for EDID read, and TMDS output compliance with HDMI 1.3a and DVI 1.0 sinks.

Technical Context

The TDA19989AET/C189,5 integrates a programmable video input formatter supporting RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 semi-planar (up to 2×12-bit), and ITU656-like formats (up to 1×12-bit) with selectable single/double-edge pixel clock sampling. Its internal color space converter handles RGB↔YCbCr conversion and supports xvYCC for extended gamut.

It features a dedicated HDCP 1.3 cipher block with keys stored in on-chip OTP memory, a CEC interface for home appliance network control, and a PLL-based serializer enabling TMDS transmission at 250 MHz–1.5 GHz. System control is implemented via I²C-bus slave interface, while DDC-bus master handles EDID communication.

FAQ

What video input formats does the TDA19989AET/C189,5 support?

The TDA19989AET/C189,5 supports RGB 4:4:4 (3×8-bit), YCbCr 4:4:4 (3×8-bit), YCbCr 4:2:2 semi-planar (up to 2×12-bit), and YCbCr 4:2:2 ITU656-like (up to 1×12-bit). Input synchronization can be external (HSYNC/VSYNC/DE) or embedded (SAV/EAV), with pixel clock sampling configurable for rising edge, falling edge, or both. This flexibility allows the TDA19989AET/C189,5 to interface directly with diverse image signal processors and application processors without external format conversion.

Does the TDA19989AET/C189,5 include built-in HDCP key storage?

Yes, the TDA19989AET/C189,5 integrates a non-volatile OTP (One-Time Programmable) memory that securely stores HDCP 1.3 encryption keys on-die. This eliminates the need for external key storage components and prevents key extraction, meeting content protection requirements for premium video distribution. The TDA19989AET/C189,5 performs full HDCP authentication and encryption in hardware, ensuring compliance with HDMI Licensing Administrator specifications.

How does the CEC functionality work on the TDA19989AET/C189,5?

The TDA19989AET/C189,5 implements a fully compliant HDMI 1.3 CEC interface on the CEC pin (H7), operating as an open-drain bidirectional bus. It enables system-level control commands - such as Standby, One Touch Play, or System Audio Control - to be transmitted over a single wire to other CEC-enabled devices. No external transceiver is needed, reducing BOM count and PCB complexity. The TDA19989AET/C189,5 handles CEC message framing, arbitration, and error checking per the HDMI CEC specification.

What power supply requirements does the TDA19989AET/C189,5 have?

The TDA19989AET/C189,5 operates exclusively from a 1.8 V supply across all domains: VDDA(TMDS), VDDD(IO), VDDA(PLL), VDDA(analog), and VDDDC. All digital and analog I/O pins are LV-CMOS 1.8 V compatible and tolerate up to 3.3 V, simplifying interface design with mixed-voltage SoCs. Its low-power architecture supports Standby and Sleep modes to minimize quiescent current when the HDMI link is inactive - a critical feature for battery-operated TDA19989AET/C189,5 applications.

Can the TDA19989AET/C189,5 handle audio and video simultaneously?

Yes, the TDA19989AET/C189,5 concurrently processes video and audio streams: it accepts up to 3×8-bit video (RGB or YCbCr) at up to 150 MHz pixel rate and either two I²S-bus channels or one S/PDIF channel with audio sampling rates up to 192 kHz. Audio data is packetized and inserted into the HDMI data island alongside video, enabling synchronized high-fidelity AV output. The TDA19989AET/C189,5 manages timing alignment, ACR generation, and null packet insertion per HDMI 1.3a specification.
