Product details
Overview
TDA19978AHV15C183 from NXP Semiconductors is a quad HDMI 1.4a-compliant receiver IC with embedded EDID memory, auto-adaptive equalizer (supporting up to 25 m cable length at 2.05 GSPS), and OTP-stored HDCP 1.4 keys. It processes HDMI streams into RGB or YCbCr 4:4:4/4:2:2 outputs and supports Deep Color (10-/12-bit) up to 205 MHz TMDS clock for HDTV (1920×1080p60) and PC formats (UXGA 1600×1200p60) in home theater AV receivers.
For engineers reviewing the TDA19978AHV15C183 datasheet, TDA19978AHV15C183 pinout, TDA19978AHV15C183 application, or TDA19978AHV15C183 equivalent, key selection considerations include HDMI 1.4a compliance, quad-input channel independence, 1.8 V/3.3 V dual-supply operation, I²C-bus programmability (400 kbit/s), and HLQFP144 package thermal performance in high-density video processing systems.
Technical Context
The TDA19978AHV15C183 integrates four independent HDMI receiver channels with per-link auto-adaptive equalizers and HDCP 1.4 repeater functionality. Its digital processing core supports real-time color space conversion (RGB↔YCbCr), output timing adjustment via tsu(Q)/th(Q), and selectable downsampling filters for Cb/Cr in 4:2:2 mode.
Audio handling includes HBR stream support (up to 768 kHz), DSD/DST decoding for SACD, and system clock generation (128/256/512 × fs) enabling external DACs like UDA1334BTS. All configuration and status monitoring occur over a 5 V-tolerant I²C-bus interface.

Laboratory testing confirms reliable operation with 0.5 mm (24 AWG) cables up to 25 meters at 2.05 gigasamples per second. This eliminates the need for external redrivers in most home theater and commercial AV installations using standard HDMI cables.
What output video formats and color depths does the TDA19978AHV15C183 provide?
The TDA19978AHV15C183 outputs RGB 4:4:4, YCbCr 4:4:4, and YCbCr 4:2:2 semi-planar (ITU-R BT.601/BT.656). Color depth is selectable via I²C-bus: 8-bit and 10-bit in all formats; 12-bit only in 4:4:4 mode. Output timing (tsu(Q)/th(Q)) is programmable to align with FPGA or ASIC capture logic, ensuring robust video interface timing margins.
Does the TDA19978AHV15C183 include embedded memory, and what is stored there?
Yes, the TDA19978AHV15C183 includes embedded EDID memory (253 shared bytes + 3 dedicated bytes per HDMI input) and non-volatile OTP memory for HDCP 1.4 keys. The EDID memory enables plug-and-play display identification per input, while the OTP storage ensures cryptographic key integrity and prevents unauthorized key extraction-critical for HDMI Licensing LLC compliance in commercial AV products.
What power supply voltages does the TDA19978AHV15C183 require, and what is its power consumption in active mode?
The TDA19978AHV15C183 requires separate 1.8 V (core, VDDC) and 3.3 V (I/O, VDDH/VDDI/VDDO) supplies. In active mode, power dissipation is 0.75 W at 720p60, 1.13 W at 1080p60, and 1.63 W in 1080p60 Deep Color mode.
