TDA19978AHV/15,518

Specialized Overview

The TDA19978AHV/15,518 is a quad HDMI 1.4a compliant receiver with embedded EDID memory and auto-adaptive equalizer. It supports TV resolutions up to 1920 × 1080p at 50/60 Hz and PC formats up to UXGA (1600 × 1200p). The device handles Deep Color in 10-bit and 12-bit modes and processes audio streams including IEC 60958/IEC 61937, One Bit Audio, DST, and HBR up to 768 kHz. It converts HDMI streams into RGB or YCbCr digital signals via LV-TTL outputs. Key electrical parameters include a maximum TMDS clock frequency of 205 MHz, supply voltages of 3.3 V and 1.8 V, and an operating temperature range of 0 °C to 70 °C.

Specialized Feature Summary

• Quad independent HDMI inputs with embedded auto-adaptive equalizer for signal integrity
• Supports HDCP 1.4 with non-volatile OTP key storage and repeater capability
• Generates system clocks (128/256/512 × fs) enabling simple external audio DAC integration
• Configurable video output formats including RGB 4:4:4 and YCbCr 4:2:2 semi-planar

Specialized Applications

• High-End TV systems
• Projector, plasma and LCD TV displays
• Home theater amplifiers and AVRs
• Rear projection TV units
• HDTV and HI-Speed video digitizers

Specialized Procurement Notes

Verify the specific ordering suffix against current NXP documentation to confirm package type and tape/reel specifications. Confirm that the HLQFP144 package variant matches your PCB footprint requirements. Ensure compliance with HDMI Licensing LLC regulations if integrating this component into commercial equipment.

Specialized Selection Notes

Select this component when a multi-input HDMI receiver with integrated equalization is required. It is suitable for designs needing support for 1080p and WUXGA formats with deep color processing. Consider the availability of external reference clocks if precise audio synchronization is critical for the target application.

Specialized Part Context

This part belongs to the TDA19978A family of HDMI receivers manufactured by NXP Semiconductors. It is designed as a direct replacement for previous generation HDMI receivers requiring quad input capabilities. The device integrates video and audio processing functions to reduce external component count in display and audio-video receiver designs.

Specialized Replacement Considerations

Check for updated revisions within the TDA19978A series. Verify pin-to-pin compatibility if substituting with other HDMI receiver ICs from different manufacturers.
