TDA9983BHW/8/C1:55

Video Processing Overview

The TDA9983BHW/8/C1:55 is an HDMI transmitter manufactured by NXP Semiconductors, designed for digital video and audio conversion. It supports a maximum pixel clock frequency of 81 MHz and operates within an ambient temperature range of 0 °C to 70 °C. The device accepts 3 × 8-bit RGB or YCBCR video streams via CMOS and LV-TTL compatible inputs. Audio processing capabilities include four I2S-bus channels and one S/PDIF channel with sampling rates up to 192 kHz. Power supplies required are 1.8 V for the core and 3.3 V for analog and digital sections.

Video Processing Feature Summary

• Integrates a programmable input formatter and color space converter supporting RGB and YCBCR formats
• Includes an intrafield deinterlacer and upsampler for standard definition to high definition scaling
• Features a hard reset function and low power dissipation with a dedicated power-down mode
• Supports HDMI 1.2a standards including DVI compatibility and hot plug detection

Video Processing Applications

• DVD players and recorders
• Set-Top Box (STB)
• AV receivers and amplifiers
• Camcorders
• Media centers PCs

Video Processing Procurement Notes

Verify the specific suffix /8/C1:55 against official documentation to confirm the 81 MHz pixel rate limitation and customer-specific version status. Ensure the HTQFP80 package variant matches the design requirements. Confirm that the ordering information aligns with current manufacturing data sheets as availability may vary.

Video Processing Selection Notes

Select this component when a lower bandwidth HDMI solution is required compared to the 150 MHz variant. The 81 MHz limit restricts output resolutions but reduces power consumption. Verify that the 3.3 V and 1.8 V supply rails are available in the target system architecture. Check if the specific customer configuration meets the application's timing constraints.

Video Processing Part Context

This part belongs to the TDA9983B family of HDMI transmitters from NXP Semiconductors. It shares the same HTQFP80 package and general functional block diagram as other variants in the series. The primary distinction lies in the maximum supported pixel clock frequency, which defines its performance tier relative to higher-speed models like the TDA9983BHW/15.

Video Processing Replacement Considerations

The TDA9983BHW/15/C1:55 serves as a higher-performance substitute offering up to 150 MHz operation. Verify pinout compatibility and register settings before substitution. No other direct public substitutes are confirmed in the provided documentation.
