TDA19977BHV/15/C1'

Specialized Overview

The TDA19977BHV/15/C1 is a triple-input HDMI 1.3a compliant receiver manufactured by NXP Semiconductors in an HLQFP144 package. It features embedded auto-adaptive equalizers supporting cable lengths up to 25 meters and includes EDID memory with 253 shared bytes plus three dedicated bytes per input. The device converts HDMI streams into RGB or YCbCr digital signals, supporting resolutions up to 1920x1080p at 50/60 Hz and WUXGA reduced blanking formats. It handles Deep Color modes (10-bit and 12-bit) and supports various audio formats including HBR, DSD, and DST. Power supplies include 1.8 V and 3.3 V rails.

Specialized Feature Summary

• Triple independent HDMI inputs with embedded auto-adaptive equalizer for signal quality improvement
• Supports Deep Color processing in 10-bit and 12-bit color depths
• Integrated EDID memory with dedicated bytes for each HDMI input
• Comprehensive audio support including HBR, DSD, and DST stream handling

Specialized Applications

• High-end TV systems
• Home theater amplifiers
• Projector, plasma, and LCD TVs
• DVD recorders
• AVR and HDMI splitters

Specialized Procurement Notes

Verify the specific suffix 'C1' against official documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with the HLQFP144 thermal enhanced low profile quad flat package requirements. Confirm that the component meets lead-free (Pb) standards as specified in the ordering information section of the datasheet.

Specialized Selection Notes

Select this model when a triple-input HDMI receiver with integrated HDCP decryption is not required, as the B variant lacks the OTP memory found in the A variant. Consider the embedded equalizer capabilities for long cable runs up to 25 meters. Verify power supply requirements for 1.8 V and 3.3 V domains during system design.

Specialized Part Context

This component belongs to the TDA19977 family of HDMI receivers from NXP Semiconductors. It serves as a digital processing interface for converting HDMI source data into parallel digital video and audio signals suitable for downstream media processors. The B variant specifically omits the HDCP repeater functionality present in the A variant.

Specialized Replacement Considerations

TDA19977AHV is the primary functional substitute within the same family, differing only by the inclusion of non-volatile OTP memory for HDCP key storage.
