Product details
Overview
TDA9983BHW/8/C1,55 from NXP Semiconductors is an HDMI 1.2a-compliant transmitter IC supporting DVI compatibility, 3 × 8-bit RGB/YCBCR video input (up to 81 MHz pixel rate), four I²S audio streams (up to 192 kHz sampling), and S/PDIF input - deployed in set-top boxes and AV receivers for high-fidelity digital video/audio interface conversion.
For engineers reviewing the TDA9983BHW/8/C1,55 datasheet, TDA9983BHW/8/C1,55 pinout, TDA9983BHW/8/C1,55 application, or TDA9983BHW/8/C1,55 equivalent, key selection criteria include HDMI serializer clock capability (81 MHz max), dual-supply operation (1.8 V core / 3.3 V I/O), programmable input formatter for ITU-R BT.656-like formats, and intrafield deinterlacing with upscaling to 720p/1080i.
Technical Context
The TDA9983BHW/8/C1,55 integrates three independent PLLs: a double-edge VCLK capture PLL, a scaling PLL generating processed video clocks, and a serializer PLL enabling HDMI output at ≥10× audio sampling rate. Its video input processor accepts RGB, YCBCR 4:4:4, YCBCR 4:2:2 semi-planar (up to 2×12-bit), and ITU656-like formats with double-edge sampling support on VPA/VPB ports.
Audio processing supports concurrent I²S (4 stereo channels via AP1–AP4) and S/PDIF (via AP6), with automatic clock recovery from S/PDIF or optional external MCLK (AP5). The color space converter is fully programmable via I²C-bus and can be bypassed; the upscaler uses intelligent edge interpolation to generate 720p/1080i from SD inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pixel Clock | 81 MHz - defines maximum supported video resolution (e.g., 1080i at 60 Hz with ITU656-like input) |
| Video Input Formats | RGB 4:4:4, YCBCR 4:4:4, YCBCR 4:2:2 semi-planar (2×12-bit), ITU656-like (1×12-bit) - enables direct interfacing with diverse MPEG decoders and video processors |
| Audio Interfaces | 4× I²S-bus (8-channel PCM) + 1× S/PDIF (IEC 60958/61937) - supports uncompressed multichannel and compressed Dolby Digital/DTS bitstreams |

| RST_N | Hard reset input | Active-low asynchronous reset - required for deterministic initialization after power-up or fault recovery |
Key Features
| Feature | Design Value |
|---|---|
| Programmable input formatter | Supports dynamic reconfiguration of sync mode (external/embedded), edge sampling (rising/falling/double), and port mapping - eliminates need for external video glue logic |
| Intrafield deinterlacer + upscaler | Converts 480i/576i to 720p/1080i using intelligent edge interpolation - preserves motion fidelity without field memory overhead |
| Dual-supply architecture | 1.8 V digital core + 3.3 V I/O domains - reduces dynamic power vs. single-rail alternatives while maintaining LV-TTL/CMOS compatibility |
| S/PDIF clock recovery | Integrated PLL recovers bit clock from S/PDIF stream - removes requirement for external crystal or clock generator in audio-centric designs |
| HDMI/DVI dual-mode output | Single physical interface supports both HDMI (with HDCP-ready TMDS) and DVI-D (no audio) - simplifies board design for multi-standard displays |

FAQ
What video input formats does the TDA9983BHW/8/C1,55 support?
The TDA9983BHW/8/C1,55 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) with double-edge sampling capability. These formats are directly compatible with broadcast MPEG decoders and consumer video processors without external format conversion logic.
Does the TDA9983BHW/8/C1,55 support HDMI 1.2a audio features like Dolby Digital passthrough?
Yes, the TDA9983BHW/8/C1,55 supports HDMI 1.2a-compliant audio transport including Dolby Digital and DTS bitstreams via its S/PDIF input (AP6). It decodes IEC 61937-compressed audio and embeds it into HDMI data islands without requiring external audio processors - a core capability confirmed in Section 8.9 of the datasheet.
What is the maximum pixel clock frequency for the TDA9983BHW/8/C1,55?
The TDA9983BHW/8/C1,55 has a maximum pixel clock frequency of 81 MHz, as specified in Table 1 for the TDA9983BHW/8 variant. This supports resolutions including 1080i at 60 Hz with ITU656-like input and 720p at 60 Hz with RGB 4:4:4 input - verified under worst-case thermal and voltage conditions.
How is power sequencing handled for the TDA9983BHW/8/C1,55?
Power sequencing for the TDA9983BHW/8/C1,55 must follow the order shown in Figure 14: VDDC(1V8) must be applied before VDDD(3V3) and VDDH(3V3). Violating this sequence risks improper initialization or functional failure. The device draws 322 mW typical power and enters a 13.5–38.4 mW power-down mode when RST_N is asserted.
Can the TDA9983BHW/8/C1,55 perform video upscaling from standard definition to high definition?
Yes, the TDA9983BHW/8/C1,55 includes a programmable upscaler that converts standard-definition inputs (e.g., 480i/576i) to 720p or 1080i outputs using intelligent edge interpolation.
