TDA19989BET-C1518 개요
An HDMI transmitter IC is a digital video interface device that encodes parallel video pixel data into TMDS (Transition Minimized Differential Signaling) serial streams for transmission over HDMI or DVI links. Within the system hierarchy, it sits in the video signal chain between a graphics source such as a SoC, microcontroller, or video processor and the HDMI physical connector, converting ITU656/parallel RGB video input into a standards-compliant high-definition multimedia output.
Key features of the TDA19989BET/C1,518 include support for up to 150 MHz pixel clock rates (enabling 1080p60 resolution), compliance with HDMI v1.3a and HDMI 1.4 specifications, HDCP 1.3 content protection for encrypted media streams, and compatibility with CEA-861B, DVI 1.0, and ITU656 video standards. The device provides three 8-bit video input paths and is fully controlled through a standard I2C serial interface, allowing a host processor to configure resolution, color depth, and HDCP sessions.
Technically, the transmitter integrates TMDS clock and data serialization, audio embedding over HDMI, InfoFrame generation, and CEC (Consumer Electronics Control) messaging, reducing external component count in set-top box and AV receiver designs. The 64-TFBGA (4.5 x 4.5 mm) surface-mount package suits space-constrained consumer video boards while supporting the high-speed differential routing required for TMDS signals.
Typical applications include set-top boxes, AV receivers, digital televisions, and HDMI-enabled embedded graphics boards. The 150 MHz pixel rate covers all standard 1080p video formats and their associated embedded audio streams.
Design consideration: HDCP 1.3 operation requires careful I2C firmware handling and licensed HDCP keys; TMDS output pairs demand controlled-impedance PCB routing with matched lengths to maintain signal integrity at 150 MHz pixel rates.
Note: this part is listed as Obsolete by supplier datasheet databases (Part Status: Obsolete); it remains procurable through surplus and broker channels.

일반적인 애플리케이션
TDA19989BET-C1518 적합 용도: 6 애플리케이션s: Set-Top Box HDMI Output, AV Receiver Video Path, Embedded Graphics Display Output, Digital Television Main Board, Test and Measurement Video Instruments, Industrial HMI with HDMI Display.
Set-Top Box HDMI Output
The TDA19989BET/C1,518 fits set-top box HDMI outputs because it combines a 150 MHz pixel rate (enough for 1080p60 at 148.5 MHz) with HDCP 1.3 content protection, which pay-TV and streaming operators require for encrypted content. The transmitter accepts ITU656-compatible parallel video from the STB SoC, embeds audio, and generates HDMI InfoFrames, offloading the host processor. The 4.5 x 4.5 mm 64-TFBGA package fits dense main boards, and I2C control lets STB firmware manage EDID, CEC messaging, and HDCP sessions. Trade-off: as an obsolete part, new STB platforms should use current-generation transmitters, but this device remains practical for service replacements of existing designs.

AV Receiver Video Path
AV receivers benefit from the TDA19989BET/C1,518's integration of HDMI transmission, CEC, and audio embedding in one 150 MHz transmitter. Its CEA-861B compliance ensures correct InfoFrame and EDID handling when the receiver repeats video to a connected television, while HDCP 1.3 allows re-transmission of protected content. The I2C interface integrates with the receiver's microcontroller for input selection and format negotiation, and the three 8-bit video input paths support flexible routing. Performance consideration: at 148.5 MHz pixel clock for 1080p60, TMDS pairs require careful controlled-impedance board routing; the compact 64-TFBGA ball map supports the short, matched differential traces receivers need for clean high-definition video output.
추천
Embedded Graphics Display Output
Embedded boards built around microcontrollers or SoCs without native HDMI use the TDA19989BET/C1,518 to add a compliant HDMI 1.4 output. The device accepts parallel 8-bit RGB/ITU656 pixel data from the host graphics interface and serializes it into TMDS at up to 150 MHz, delivering 1080p60 with embedded audio. Its 4.5 x 4.5 mm 64-TFBGA footprint lets designers place the transmitter close to the HDMI connector on compact single-board computers, test instruments, or industrial HMIs. Because the host only needs an I2C bus and the parallel video port, integration effort is low; the main design task is maintaining TMDS signal integrity through length-matched, 100-ohm differential PCB routing.

Digital Television Main Board
In digital television platforms, the TDA19989BET/C1,518 serves as the HDMI source-side transmitter for on-screen user interfaces, media player functions, or broadcast video re-transmission to a panel. Its 150 MHz pixel rate covers Full HD content, HDCP 1.3 maintains content protection across the chain, and CEC enables one-remote control coordination between TV, receiver, and set-top devices - a mandatory feature in consumer TV ecosystems. The 64-TFBGA package withstands the reflow profiles of large TV main boards and offers the ball pitch that simplifies routing from the TV SoC. Note that TV makers qualifying new platforms should verify lifecycle status, as the part is obsolete and future supply depends on broker stock as of 2026-10-11.

Test and Measurement Video Instruments
Video test instruments, HDMI pattern generators, and protocol analyzers use the TDA19989BET/C1,518 as a reference HDMI source because its 150 MHz pixel rate spans all CEA-861B standard timings up to 1080p60. The I2C host interface lets instrument firmware sweep resolutions, inject test InfoFrames, and manage HDCP sessions deterministically - essential for repeatable measurements. The 3 x 8-bit video input accepts patterns directly from an FPGA pattern engine, and audio embedding allows testing of AV receivers and soundbars. In lab equipment, the 64-TFBGA's thermal and signal-integrity characteristics support continuous duty cycles, though designers must budget TMDS termination and ESD protection at the HDMI connector for reliable hot-plug operation.

Industrial HMI with HDMI Display
Industrial human-machine interface terminals increasingly mirror content to external HDMI monitors for dashboards and factory visualization. The TDA19989BET/C1,518 adds this capability to HMI controllers that output parallel RGB video, serializing it at up to 150 MHz for Full HD external displays. HDCP support is rarely required in industrial settings but costs nothing extra in this device, and I2C control integrates cleanly with existing microcontroller firmware - for example, XMC-family hosts. The 4.5 x 4.5 mm 64-TFBGA suits the compact form factors of panel-mounted terminals, and the part's surface-mount construction meets industrial reflow assembly. Long-term supply planning is critical: because the part is obsolete, industrial designs should secure buffer stock or plan a successor-family migration.

설계 노트
TMDS differential pairs must be routed as 100-ohm controlled-impedance, length-matched pairs from the 64-TFBGA balls to the HDMI connector. At the 150 MHz pixel rate (about 1.485 Gbps per TMDS channel for 1080p60), keep pair lengths within 5 mil intra-pair mismatch and place ESD protection close to the connector. Avoid stubs and layer transitions on the high-speed pairs; reference a continuous ground plane throughout.
HDCP 1.3 operation requires licensed HDCP device keys provisioned into the system and correct I2C firmware state handling; omitting proper key storage (for example, in a W25Q128FWPIG serial flash) will fail HDCP authentication with protected content. Also verify EDID handling in firmware - many field failures of TDA19989-based designs trace to incomplete EDID reading or CEC line-level misconfiguration rather than hardware faults.
Decouple each 64-TFBGA supply ball with 100 nF ceramic capacitors placed within 2 mm of the ball via, plus bulk 10 uF per supply domain. Because the TFBGA ball map interleaves power and ground balls, use via-in-pad fan-out on the inner supply balls. Estimated: check each supply domain current draw against the datasheet pin description section, as verified power figures were not available in the source data for this page.
