TDA9983BHW/8/C1,51

Video Processing Overview

The TDA9983BHW/8/C1,51 is an HDMI transmitter manufactured by NXP Semiconductors. It supports DVI and converts digital video and audio into HDMI or DVI streams. The device accepts a 3 × 8-bit RGB or YCBCR video stream with a maximum pixel rate of 81 MHz. It processes up to four I2S-bus audio streams and one S/PDIF channel, supporting sampling rates up to 192 kHz. A programmable upscaling block enables 720p/1080i output from standard definition inputs. It operates on 1.8 V and 3.3 V power supplies within an ambient temperature range of 0 °C to 70 °C.

Video Processing Feature Summary

• Integrates a programmable input formatter and color space conversion block for flexible video format compatibility.
• Includes an intrafield deinterlacer and scaler to enable upscaling from standard definition to 720p/1080i outputs.
• Supports multiple audio interfaces including four I2S-bus channels and one S/PDIF channel for high-quality audio transmission.
• Features low power dissipation capabilities with a dedicated power-down mode controlled via the I2C-bus interface.

Video Processing Applications

• DVD players and recorders
• Set-Top Box (STB)
• AV receivers and amplifiers
• Camcorders
• Digital still cameras

Video Processing Procurement Notes

Verify the specific suffix /8/C1,51 against official NXP documentation to confirm it denotes the customer-specific version limited to an 81 MHz maximum clock frequency. Ensure the HTQFP80 package type matches your PCB footprint requirements. Confirm that the component status aligns with your long-term supply needs, as availability may vary.

Video Processing Selection Notes

Select this component when designing systems requiring HDMI output with a maximum pixel clock of 81 MHz. It is suitable for applications needing integrated upscaling from SD to HD resolutions. Consider its support for both I2S and S/PDIF audio inputs if multi-channel audio integration is required without external codecs.

Video Processing Part Context

This part belongs to the TDA9983B family of HDMI transmitters. While the broader family includes versions supporting up to 150 MHz pixel rates, the /8 variant is specifically designated for lower-frequency applications. It shares the same HTQFP80 package and core functionality but differs in maximum operating speed specifications.

Video Processing Replacement Considerations

The TDA9983BHW/15/C1,51 is a confirmed substitute within the same family, offering a higher maximum clock frequency of 150 MHz while maintaining pin compatibility and functional features.
