TDA19989BET/C1551 Descripción general
An HDMI transmitter is a video interface IC that converts parallel or digital video bus data into the TMDS (Transition Minimized Differential Signaling) serial stream defined by the HDMI and DVI standards. Within the system hierarchy, it sits in the video signal chain between a graphics source (SoC, FPGA, or video processor) and the physical HDMI connector, and belongs to the broader class of interface ICs and video processing ICs.
Key features include the 150 MHz pixel clock supporting 1080p60 video, compliance with CEA-861B, DVI 1.0, and HDMI v1.3a signaling with HDMI 1.4 capability, and integrated HDCP 1.3 cipher engine for protected content. An I2C host interface programs registers, controls the HDCP state machine, and reads EDID from the sink via DDC. CEC support enables consumer electronics control channel communication over the HDMI cable.
Architecturally, the TDA19989 family combines input video formatting, TMDS serialization, audio embedding, infoframe generation, and HDCP encryption in a single low-power CMOS die. The 3 x 8-bit video input bus accepts RGB or YCbCr formats, while audio is accepted via I2S or S/PDIF-style inputs and multiplexed into the TMDS stream.
Typical applications include set-top boxes, Blu-ray/DVD players, digital media adapters, automotive infotainment head units, and embedded boards with HDMI display outputs. Its compact 4.5 mm BGA suits space-constrained consumer and industrial designs.
Designers should note that HDCP license agreements govern use of the cipher, and that the 64-TFBGA requires controlled-impedance TMDS routing on the PCB. Note the part is listed as obsolete by some sources, so verify lifecycle for new designs.

Aplicaciones típicas
TDA19989BET/C1551 es adecuado para 6 aplicacións: Set-Top Boxes and Media Players, Embedded Boards with HDMI Output, DVD and Blu-ray Disc Players, Automotive Infotainment Head Units, Test and Measurement Instruments, Digital Media Adapters and Dongles.
Set-Top Boxes and Media Players
Set-top boxes and streaming media players require a compact HDMI source that outputs 1080p60 with content protection. The TDA19989BET/C1551 fits this role with its 150 MHz pixel rate, HDCP 1.3 cipher for operator-protected content, and CEC for remote-control passthrough over the HDMI cable. Its 3 x 8-bit parallel input connects directly to SoC video buses without an external serializer, and I2C register control integrates simply with main-software HDMI drivers. The 4.5 x 4.5 mm 64-TFBGA keeps the board area small. Because the part is obsolete, new set-top designs should plan last-time-buy quantities or an NXP family successor.
Recomendado
Embedded Boards with HDMI Output
Single-board computers, evaluation platforms, and industrial HMIs need a full-HDMI display output. The TDA19989BET/C1551 accepts a parallel RGB/YCbCr bus typical of SoC LCDC outputs and serializes it to HDMI at up to 150 MHz, supporting 1080p60. Its CEA-861B and DVI 1.0 compliance allows either HDMI or DVI connectors from the same transmitter. EDID is read from the sink through the DDC lines managed over I2C, and the HDCP 1.3 engine can be enabled when DRM playback is required. Designers should follow the NXP reference layout for TMDS trace impedance and place the 64-TFBGA close to the connector.
Recomendado
DVD and Blu-ray Disc Players
Disc players output protected full-HD video, making HDCP mandatory. The TDA19989BET/C1551 provides the HDCP 1.3 cipher, 150 MHz pixel rate for 1080p content, and audio embedding into the TMDS stream so a single HDMI cable carries sound and picture. Its ITU656 and parallel video inputs match classic DVD decoder chipsets, simplifying drop-in HDMI output stages for existing player platforms. CEC support enables one-touch-play behavior required by consumer certification. Note that the part status is obsolete: existing player designs should secure stock via Rochester Electronics or migrate to an active NXP HDMI transmitter family member.
Recomendado
Automotive Infotainment Head Units
In-vehicle head units and rear-seat entertainment systems benefit from an HDMI-class digital video link between the SoC and display. The TDA19989BET/C1551 supplies a 1080p-capable transmitter with HDCP for protected navigation and streaming content. Its compact 64-TFBGA (4.5 x 4.5 mm) package suits dashboard space constraints, and the I2C control interface integrates with vehicle processor stacks. However, the verified data carries no AEC-Q100 claim for this ordering code, so automotive projects must confirm the qualification grade with NXP or select an explicitly automotive-qualified family member before deployment.
Recomendado
Test and Measurement Instruments
Bench instruments and data-acquisition boxes increasingly offer HDMI outputs for external monitors. The TDA19989BET/C1551 provides a straightforward path from an FPGA or video processor parallel bus to an HDMI port at up to 150 MHz pixel rate, with no external serializer needed. EDID negotiation via DDC over I2C lets the instrument adapt output timing to any monitor. The DVI 1.0 compliance also allows a DVI connector variant of the same design. Because HDCP can be left unenabled, non-protected test imagery avoids HDCP licensing complexity, while the cipher remains available if required.
Recomendado
Digital Media Adapters and Dongles
Compact HDMI dongles and media adapters need the smallest possible transmitter footprint. At 4.5 x 4.5 mm with 64 balls, the TDA19989BET/C1551 minimizes PCB area behind the HDMI connector while delivering full 1080p60 throughput and HDCP 1.3 for licensed streaming apps. CEC support enables wake and control interactions expected by TV ecosystems, and audio embedding removes the need for separate audio cables. Thermal load is low at typical pixel rates, suiting enclosed plastic housings. As the part is obsolete, dongle platforms should qualify a successor NXP transmitter or secure last-time-buy inventory.

Diferenciadores clave
- Integrated HDCP 1.3 cipher engine (frente a TDA19989AET/C1551)
- HDMI 1.4 feature capability at 150 MHz (frente a TDA19988BET/C1551)
- Compact 4.5 x 4.5 mm 64-TFBGA footprint (frente a External-serializer solutions)
Notas de diseño
The TMDS differential pairs leaving the 64-TFBGA must be routed as 100-ohm controlled-impedance pairs with matched intra-pair skew, following the NXP TDA19989 family reference layout. Keep TMDS traces as short as possible and place the HDMI connector within a few centimeters of the transmitter. Avoid routing TMDS across plane splits, and provide a solid ground reference layer beneath the pairs to control EMI from the multi-hundred-Mbps serialized data.
Use of the HDCP 1.3 cipher requires an HDCP license from DCP LLC; shipping protected-content products without one is a violation. Also confirm that the /C1551 ordering code's qualification grade matches your environment - no AEC-Q100 claim appears in the verified data for this part. Finally, the part is obsolete: qualify a successor and place last-time-buy orders early, since broker stock varies in date code and authenticity. Rochester Electronics is an authorized aftermarket source.
Decouple each supply ball of the TDA19989BET/C1551 with 100 nF ceramic capacitors placed within 1-2 mm of the ball via, plus one bulk capacitor per supply rail near the IC. Sequence supplies per the NXP family datasheet power-up requirements and ensure the I2C pull-ups reference the correct IO bank voltage. Verify the exact supply domains and voltages against the official NXP datasheet, as the verified web data does not list the supply rails.
The 3 x 8-bit parallel video input toggling at up to 150 MHz demands attention to bus skew and crosstalk: keep the video bus length-matched within the tolerance stated in the NXP datasheet, add series termination where the SoC driver strength requires it, and route the pixel clock away from the TMDS pairs to avoid coupling jitter into the serialized output. Ground-return vias adjacent to the bus reduce loop area on high-layer-count boards.
