Product details
Overview
TDA9983BHW/8/C1,51 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 rate), and S/PDIF audio input - deployed in set-top boxes and AV receivers for high-fidelity digital video/audio interface conversion.
For engineers reviewing the TDA9983BHW/8/C1,51 datasheet, TDA9983BHW/8/C1,51 pinout, TDA9983BHW/8/C1,51 application, or TDA9983BHW/8/C1,51 equivalent, key selection criteria include HDMI serializer operation up to 1.5 GHz, programmable input formatter for ITU656-like and semi-planar YCBCR 4:2:2 formats, intrafield deinterlacing, and dual-voltage operation (1.8 V core / 3.3 V I/O).
Technical Context
The TDA9983BHW/8/C1,51 integrates three independent PLLs: a double-edge VCLK capture PLL, a scaling PLL for programmable video processing clock generation, and a serializer PLL enabling HDMI output at ≥10× audio sampling rate. It supports embedded (SAV/EAV) and external HREF/VREF/DE synchronization with configurable edge sampling (rising/falling/double).
Its video input processor accepts RGB 4:4:4, YCBCR 4:4:4, YCBCR 4:2:2 semi-planar (up to 2×12-bit), and ITU656-like (up to 1×12-bit) formats across three 8-bit ports (VPA/VBP/VPC), with real-time color space conversion (RGB↔YCBCR), upsampling from 4:2:2 to 4:4:4, and intrafield deinterlacing - all controlled via I²C-bus slave interface (A0/A1 address pins).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDA9983BHW/15/C1 | Higher max pixel clock (150 MHz vs. 81 MHz); supports 1080p60 input; higher power consumption (361 mW typical) | Required for full HD 1080p source interfaces; not suitable for cost-sensitive 720p-only designs | Select TDA9983BHW/15/C1 only when 1080p60 video input capability is mandatory |
| Si2920-AE | Single-chip HDMI 1.3 transmitter with integrated HDCP engine; no internal scaler/deinterlacer; 1.2 V core supply | Lacks upscaling and intrafield deinterlacing; targets HDCP-secured content distribution, not legacy source adaptation | Choose Si2920-AE for HDCP compliance-critical applications where external video processing is available |

FAQ
What video input formats does the TDA9983BHW/8/C1,51 support?
The TDA9983BHW/8/C1,51 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) formats. It accepts both external synchronization (HSYNC/VSYNC/DE) and embedded sync (SAV/EAV), with configurable rising/falling/double-edge sampling on VCLK. These capabilities are confirmed in Tables 5–13 of the official NXP datasheet for TDA9983BHW/8/C1,51.
Does the TDA9983BHW/8/C1,51 include a built-in scaler or deinterlacer?
Yes, the TDA9983BHW/8/C1,51 integrates a programmable upscaling block that converts standard-definition inputs (e.g., 480i) to 720p or 1080i outputs using intelligent edge interpolation, and an intrafield deinterlacer for progressive scan conversion. This functionality is explicitly documented in Section 1 (General description) and Section 8.5 (Upsampler) of the TDA9983BHW/8/C1,51 datasheet.
What audio interfaces are supported by the TDA9983BHW/8/C1,51?
The TDA9983BHW/8/C1,51 supports four I2S-bus audio input channels (AP1–AP4, up to 8 channels total) and one S/PDIF input channel (AP6), with sampling rates up to 192 kHz. S/PDIF supports both uncompressed PCM (IEC 60958) and compressed formats (Dolby Digital, DTS). Audio format selection is controlled via I²C registers, and only one format (I2S or S/PDIF) may be active at a time - as specified in Sections 1, 2, and 8.8–8.10 of the TDA9983BHW/8/C1,51 datasheet.
What is the maximum HDMI data rate supported by the TDA9983BHW/8/C1,51?
The TDA9983BHW/8/C1,51 HDMI serializer operates from 250 MHz to 1.50 GHz, enabling transmission of 720p, 1080i, and 1080p video resolutions. Its 81 MHz maximum pixel clock (TDA9983BHW/8 version) corresponds to 74.25 MHz for 720p50/60 and 74.1758 MHz for 1080i50/60, consistent with HDMI 1.2a specifications. This range is defined in the "Features" section and Table 1 (Quick reference data) of the TDA9983BHW/8/C1,51 datasheet.
How is the TDA9983BHW/8/C1,51 powered and what are its voltage requirements?
The TDA9983BHW/8/C1,51 requires five separate supplies: VDDC(1V8) = 1.65–1.95 V (core), VDDA(FRO_3V3) = 3.0–3.6 V (FRO analog), VDDA(PLL_3V3) = 3.0–3.6 V (PLL analog), VDDD(3V3) = 3.0–3.6 V (digital I/O), and VDDH(3V3) = 3.0–3.6 V (HDMI transmitter). Power-up sequencing must follow Figure 14 in the datasheet to prevent latch-up. These values are specified in Table 1 (Quick reference data) and Section 7.2 (Pin description) of the TDA9983BHW/8/C1,51 datasheet.
