NXP Semiconductors TDA19989AET/C185:5

Overview

TDA19989AET/C185:5 from NXP Semiconductors is a low-power HDMI 1.3a transmitter IC for mobile video interfaces, supporting 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 - deployed in digital cameras, portable media players, and ultra-mobile PCs.

For engineers reviewing the TDA19989AET/C185:5 datasheet, TDA19989AET/C185:5 pinout, TDA19989AET/C185:5 application, or TDA19989AET/C185:5 equivalent, key selection criteria include TMDS output compliance (250 MHz–1.5 GHz), 1.8 V LV-CMOS I/O tolerance, TFBGA64 package constraints, and embedded CEC/HPD management for compact HDMI source designs.

Technical Context

The TDA19989AET/C185:5 integrates a programmable video input formatter with support for RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 semi-planar (up to 2×12-bit), and ITU-R BT.656-like formats, plus configurable edge-triggered pixel clock sampling (SDR/DDR). Its internal color space converter enables bidirectional RGB↔YCbCr mapping.

It features an I²C-bus slave interface for configuration, an I²C-bus master DDC interface for EDID reading, a dedicated CEC open-drain I/O, hot-plug detect (HPD) with 5 V tolerance, and four independent TMDS differential output channels (TX0±, TX1±, TX2±, TXC±) operating at 250 MHz–1.5 GHz.

FAQ

What video input formats does the TDA19989AET/C185:5 support?

The TDA19989AET/C185:5 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 ITU-R BT.656-like (up to 1×12-bit). Format selection and port mapping are configured via I²C registers VIP_CNTRL_0–2, enabling adaptation to diverse SoC video outputs without hardware changes.

Does the TDA19989AET/C185:5 include HDCP encryption?

Yes, the TDA19989AET/C185:5 implements full HDCP 1.3 compliance, including on-chip SHA-1 calculation and internal non-volatile OTP memory for secure storage of HDCP keys - eliminating the need for external key management circuitry and simplifying system-level security certification.

How is CEC functionality implemented in the TDA19989AET/C185:5?

The TDA19989AET/C185:5 integrates a dedicated CEC transceiver on the CEC pin (H7), operating as an open-drain bidirectional interface compliant with HDMI 1.3 CEC specifications. It handles physical layer signaling and message framing internally, allowing direct connection to the HDMI connector without external components.

What power supply requirements does the TDA19989AET/C185:5 have?

The TDA19989AET/C185:5 requires five 1.8 V supplies: VDDA(TMDS), VDDA(PLL), VDDA, VDDD(IO), and VDDDC. All digital and analog I/O pins are LV-CMOS 1.8 V compatible and 3.3 V tolerant, simplifying level-shifting design while maintaining low active and standby power consumption.

Is the TDA19989AET/C185:5 pin-compatible with other NXP HDMI transmitters?

No documented pin-to-pin compatibility exists between the TDA19989AET/C185:5 and other NXP HDMI transmitters such as TDA19988 or TDA19987. The TDA19989AET/C185:5 uses a unique TFBGA64 pinout optimized for its 3-port video input architecture and integrated CEC/HPD functions - PCB layout must be designed specifically for this part.
