TDA19978AHV/15/C18

Specialized Overview

The TDA19978AHV/15/C18 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, WUXGA (1920 × 1200p at 60 Hz), and PC formats up to UXGA (1600 × 1200p at 60 Hz). The device handles Deep Color modes in 10-bit and 12-bit (up to 205 MHz TMDS clock) and processes color gamut metadata. Audio capabilities include IEC 60958/IEC 61937 streams, HBR audio up to 768 kHz, and DSD/DST support for SACD. It converts HDMI streams into RGB or YCbCr digital signals via LV-TTL outputs.

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure compatibility with HDMI Licensing LLC requirements if integrating into commercial equipment. Confirm that the HLQFP144 package aligns with your PCB layout constraints and thermal management strategy before finalizing procurement.

Specialized Selection Notes

Select this component when a design requires four simultaneous HDMI sources with robust signal integrity features like adaptive equalization. It is suitable for applications needing deep color processing and high-bitrate audio extraction. Verify that the required video resolutions and audio formats fall within the specified HDMI 1.4a and HDCP 1.4 standards supported by the device.

Specialized Part Context

This part belongs to NXP's HDMI receiver family designed for consumer electronics. It integrates digital controllers and PHY logic to simplify SoC design. The device is manufactured using CMOS process technology and operates on 1.8 V and 3.3 V power supplies, providing a compact solution for multi-input display systems.

Specialized Replacement Considerations

Check for newer revisions of the TDA19978A series or alternative quad HDMI receivers from NXP. Ensure any substitute maintains HDMI 1.4a compliance and similar pinout configurations if board-level replacement is necessary.
