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 digital outputs and supports Deep Color (10-/12-bit) up to 205 MHz TMDS clock for HDTV (1920×1080p60) and PC formats (UXGA 1600×1200p60).
For engineers reviewing the TDA19978AHV15C183 datasheet, TDA19978AHV15C183 pinout, TDA19978AHV15C183 application, or TDA19978AHV15C183 equivalent, key selection considerations include quad-input HDMI signal integrity, I²C-controllable video timing (tsu(Q)/th(Q)), 1.8 V/3.3 V dual-supply operation, and support for HBR audio (up to 768 kHz) and SACD/DST stream decoding.
Technical Context
The TDA19978AHV15C183 integrates four independent HDMI receivers with per-link auto-adaptive equalization and HDCP 1.4 repeater functionality. Its architecture includes an embedded oscillator (or external crystal option), programmable color space conversion (RGB↔YCbCr), and dedicated audio processing blocks supporting IEC 60958/61937, HBR, DSD, and DST streams.
Video output formatting is configurable via I²C: YCbCr 4:2:2 semi-planar (ITU-R BT.601/BT.656), RGB 4:4:4, or downsampling-by-two with selectable Cb/Cr filters. System clock generation provides 128/256/512 × fs outputs to drive external DACs like the UDA1334BTS without integrated PLLs.
