Product details
Overview
TDA19988BHN/C1,557 from NXP Semiconductors is a low-power HDMI 1.4a transmitter with 3×8-bit RGB/YCbCr video input support, 165 MHz pixel rate, integrated CEC controller, and HVQFN64 package (9 mm × 9 mm). It delivers HDMI output for mobile and STB applications without HDCP encryption, enabling cost-sensitive designs requiring DVI 1.0 backward compatibility and 1080p/60 Hz resolution.
For engineers reviewing the TDA19988BHN/C1,557 datasheet, TDA19988BHN/C1,557 pinout, TDA19988BHN/C1,557 application, or TDA19988BHN/C1,557 equivalent, key selection criteria include its no-HDCP configuration, dual-edge ITU656 support, TMDS swing adjustment via EXT_SWING pin, I²C slave/master DDC interface, and 1.8 V LV-CMOS compatible video/audio inputs.
Technical Context
The TDA19988BHN/C1,557 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 with selectable single/dual-edge pixel clock sampling. Its internal color space converter handles RGB↔YCbCr conversion and supports xvYCC for extended gamut.
It embeds a PLL-based serializer driving four TMDS channels (TX0±, TX1±, TX2±, TXC±) at up to 1.5 GHz, plus dedicated CEC open-drain I/O and Hot Plug Detect (HPD) with 5 V tolerance. Power management includes Standby mode (18 µW typical) and operation at 55 mW for 720p/24 Hz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDA19988AHN/C1 | Includes HDCP 1.4 cipher block with internal OTP key storage; identical pinout and electrical specs | Required for content-protected media playback (e.g., Blu-ray, streaming apps) | Select when HDCP compliance is mandated by content providers or platform certification |
| Si2920ACNU | Single-chip HDMI 1.4 transmitter with integrated HDCP, but no CEC support; QFN64 package | Lacks CEC functionality; requires external microcontroller for system control | Choose if HDCP is needed but CEC is not used, and board layout allows different pin assignment |
Compared with TDA19988AHN/C1, the TDA19988BHN/C1,557 removes HDCP licensing complexity and cost while retaining full CEC, video formatting, and low-power operation; versus Si2920ACNU, it provides native CEC integration and broader video format flexibility at the expense of HDCP capability.

FAQ
Does TDA19988BHN/C1,557 support HDCP encryption?
No, TDA19988BHN/C1,557 does not include an HDCP cipher block or internal OTP key memory. It is explicitly designated as the "without HDCP" variant per NXP's ordering information table. This makes TDA19988BHN/C1,557 suitable for non-content-protected applications such as STB video output, industrial displays, or legacy DVI interfacing where HDCP licensing is unnecessary or prohibited.
What video input formats does TDA19988BHN/C1,557 accept?
TDA19988BHN/C1,557 accepts 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) formats. Input synchronization supports external HSYNC/VSYNC/DE or embedded timing, with ITU656 allowing single- or dual-edge pixel clock sampling for 720p/1080i at 148.5 MHz.
How is the TMDS output swing adjusted on TDA19988BHN/C1,557?
The TMDS output swing on TDA19988BHN/C1,557 is controlled via the EXT_SWING pin, an open-drain output requiring a 10 kΩ ±1 % pull-down resistor to analog ground. This sets nominal differential amplitude per HDMI specification; no external DAC or voltage reference is needed, simplifying layout and reducing component count.
Can TDA19988BHN/C1,557 be used in place of TDA9981?
Yes, TDA19988BHN/C1,557 is specified by NXP as a functional replacement for TDA9981 transmitters, offering increased features including HDMI 1.4a compliance, xvYCC support, enhanced CEC, and improved power efficiency. Pin compatibility is maintained in the HVQFN64 package, though register mapping and initialization sequences differ and require firmware update.
What is the role of the INT pin on TDA19988BHN/C1,557?
The INT pin on TDA19988BHN/C1,557 serves a dual function: in operation mode, it acts as an open-drain interrupt output signaling HDMI events (e.g., HPD assertion, CEC message arrival); in calibration mode, it becomes an input for a 10 ms ±1 % calibration pulse. Function selection is controlled via I²C register configuration, enabling flexible system-level event handling.
