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 clock), four I2S-bus audio streams (up to 192 kHz sampling), and S/PDIF input - designed for standard-definition-to-HD upscaling in consumer AV systems.
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 its 81 MHz max pixel rate, dual-supply operation (1.8 V core / 3.3 V I/O), programmable input formatter for ITU656-like and semi-planar YCBCR formats, and HDMI serializer with TXC±/TX0±/TX1±/TX2± differential outputs.
Technical Context
The TDA9983BHW/8/C1:55 implements three dedicated PLLs: a double-edge VCLK capture PLL, a scaling PLL for interpolated output timing, and a serializer PLL generating HDMI TMDS clock 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 (up to 1×12-bit) formats with rising/falling/both-edge sampling support.
It integrates an intrafield deinterlacer, programmable color space converter (RGB ↔ YCBCR), and intelligent edge interpolation-based upscaler enabling 720p/1080i output from SD sources. Audio processing supports simultaneous I2S (4 stereo channels) or S/PDIF (L-PCM or compressed bitstream), with automatic clock recovery from S/PDIF or optional external MCLK.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pixel Clock | 81 MHz - defines maximum supported resolution/timing (e.g., 480p/576p @ 54.054 MHz, 1080p @ 148.5 MHz not supported) |
| Video Input Formats | RGB 4:4:4, YCBCR 4:4:4 (3×8-bit), YCBCR 4:2:2 semi-planar (2×12-bit), ITU656-like (1×12-bit) - enables direct interface with diverse MPEG decoders and video processors |
| Audio Interfaces | 4× I2S-bus (8-channel uncompressed) or 1× S/PDIF (2-channel PCM or multichannel compressed) - selectable via I²C; no concurrent use |

Key Features
| Feature | Design Value |
|---|---|
| Programmable Input Formatter | Supports embedded/external sync, double-edge sampling, and real-time port remapping - eliminates need for external video glue logic |
| Intrafield Deinterlacer + Upscaler | Converts 480i/576i to 720p/1080i using intelligent edge interpolation - preserves motion integrity without field memory |
| Dual-Supply Architecture | 1.8 V digital core + 3.3 V I/O/HDMI supplies - reduces dynamic power vs. single-rail while maintaining interface compatibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7513WBCPZ | Supports HDMI 1.4 (4K@30), integrated CEC controller, single 1.8 V supply; no native ITU656-like input support | Better suited for newer UHD designs requiring HDCP 2.2 or CEC; lacks intrafield deinterlacing for legacy SD sources | Select ADV7513WBCPZ when upgrading to HDMI 1.4 features; retain TDA9983BHW/8/C1:55 for cost-sensitive SD/HD transition systems with ITU656 legacy interfaces |
| Si2177-A30 | Integrated tuner + demodulator + HDMI transmitter; supports DVB-C/T/S2; no standalone video input ports | Targeted at broadcast receiver SoC replacement; not a drop-in replacement due to missing VPA/VPB/VPC and I2S interfaces | Choose Si2177-A30 only for tuner-integrated STB designs; TDA9983BHW/8/C1:55 remains optimal for discrete video source interfacing |
Compared with ADV7513WBCPZ and Si2177-A30, the TDA9983BHW/8/C1:55 provides unmatched flexibility for legacy video formats (ITU656-like, semi-planar YCBCR) and integrated SD-to-HD upscaling - making it the preferred choice for retrofitting existing MPEG decoder platforms without redesigning video front-end logic.

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 embedded or external synchronization. It also allows double-edge sampling on VCLK for ITU656-like formats. These capabilities are confirmed in Tables 5–13 of the official NXP datasheet for TDA9983BHW/8/C1:55.
Does the TDA9983BHW/8/C1:55 support HDMI 2.0 or higher?
No, the TDA9983BHW/8/C1:55 is compliant with HDMI 1.2a and DVI 1.0 specifications only. Its maximum pixel clock is 81 MHz, limiting support to resolutions such as 720p60 or 1080i60 - not 1080p60 (148.5 MHz) or 4K. This is explicitly stated in Table 1 (Quick Reference Data) and Section 1 (General Description) of the TDA9983BHW/8/C1:55 datasheet.
How does the TDA9983BHW/8/C1:55 handle audio input selection between I2S and S/PDIF?
The TDA9983BHW/8/C1:55 uses I²C register configuration to select either I2S (via AP0–AP4) or S/PDIF (via AP6) - both cannot operate simultaneously. AP5 serves as optional MCLK for S/PDIF clock recovery. This behavior is defined in Section 8.8 and Table 15 of the TDA9983BHW/8/C1:55 datasheet, with register-level control documented in the programming guide.
What is the function of the EXT_SWING pin on the TDA9983BHW/8/C1:55?
The EXT_SWING pin on the TDA9983BHW/8/C1:55 sets HDMI output voltage swing by connecting an external resistor between EXT_SWING and VDDH(3V3). Resistance value determines TMDS output amplitude per Section 8.14.1 of the datasheet, enabling compliance with HDMI cable loss requirements across varying board layouts and connector types.
Is the TDA9983BHW/8/C1:55 pin-compatible with the TDA9983BHW/15/C1 version?
Yes, the TDA9983BHW/8/C1:55 and TDA9983BHW/15/C1 share identical HTQFP80 (SOT841-4) packaging and pinout - differing only in maximum pixel clock rating (81 MHz vs. 150 MHz) and associated AC performance limits. This is confirmed in Tables 2 and 3 of the TDA9983BHW/8/C1:55 datasheet under "Ordering Information" and "Survey of type numbers".
