Product details
Overview
TDA19977AHV/15C184 from NXP Semiconductors is a triple-input HDMI 1.3a-compliant receiver IC with embedded EDID memory, auto-adaptive equalizer (supporting up to 25 m cable length), HDCP 1.2 decryption (OTP-stored keys), and programmable RGB/YCbCr video output formatting. It delivers 1080p/60 Hz video decoding with Deep Color (10-/12-bit), HBR audio support (up to 768 kHz), and I2S/S/PDIF audio outputs - deployed in high-end AV receivers and HDMI splitters.
For engineers reviewing the TDA19977AHV/15C184 datasheet, TDA19977AHV/15C184 pinout, TDA19977AHV/15C184 application, or TDA19977AHV/15C184 equivalent, key selection criteria include HDMI input count (3), HDCP capability (TDA19977A-only), 144-pin HLQFP package, 235 MHz max pixel clock, and LV-TTL video port compatibility with I2C-configurable timing and color space conversion.
Technical Context
The TDA19977AHV/15C184 implements a full HDMI 1.3a receiver stack including HDCP 1.2 decryption (exclusive to TDA19977A variant), auto-adaptive equalization per channel, and packet extraction for InfoFrames, color gamut metadata, and HBR/DST/OBA streams. Its architecture integrates three independent HDMI receivers, a shared video formatter supporting RGB 4:4:4, YCbCr 4:4:4, and ITU-R BT.601/BT.656 4:2:2 semi-planar outputs, and an audio subsystem with 128/256/512×fs system clock generation.
It features dual-domain power management (1.8 V core + 3.3 V I/O), I2C-bus slave interface (400 kbit/s, 5 V tolerant), and hardware-level activity detection across 22.5–235 MHz to auto-select active inputs. All video timing parameters (tsu(Q), th(Q)), color space conversion coefficients, and downsampling filters are software-configurable via I2C without external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si2920-AE | Single-input HDMI 1.3 receiver; no HDCP; 1080p60 support only; QFN64 package | Lacks triple-input capability, HDCP, and Deep Color - suitable only for cost-sensitive single-source designs | Select when HDCP and multi-input aggregation are unnecessary and board space is constrained |
| TDA19988HN/C1 | Triple-input HDMI 1.4 receiver; supports 4K2K@30Hz; integrated CEC controller; same HLQFP144 package | Higher bandwidth (340 MHz), HDCP 2.2, and CEC enable next-gen UHD systems but require firmware update | Choose for future-proofing with 4K readiness and CEC integration; not drop-in compatible due to register map changes |
Compared with Si2920-AE, TDA19977AHV/15C184 provides triple-input flexibility and HDCP 1.2 security essential for premium AV equipment; versus TDA19988HN/C1, it offers proven stability for 1080p60 deployments but lacks 4K and HDCP 2.2 required for newer content ecosystems.

Keys are stored in non-volatile OTP (One-Time Programmable) memory embedded within the IC, ensuring maximum security against extraction or cloning. The TDA19977AHV/15C184 manages full HDCP repeater authentication, including automatic DDC bus selection and re-key calculation, without CPU intervention.
What video output formats and bit depths does TDA19977AHV/15C184 support?
TDA19977AHV/15C184 supports RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 semi-planar (ITU-R BT.601), and YCbCr 4:2:2 (ITU-R BT.656). Bit depth is selectable via I2C: 8-bit and 10-bit in all formats; 12-bit only in 4:4:4 mode. The TDA19977AHV/15C184 also enables programmable video port bit mapping (e.g., VP[29:20] for R/G/B) to optimize PCB layout with downstream processors.
How does the auto-adaptive equalizer in TDA19977AHV/15C184 improve signal integrity?
The auto-adaptive equalizer in TDA19977AHV/15C184 continuously measures incoming HDMI signal quality per channel and dynamically adjusts equalization settings to compensate for cable loss and jitter. This enables reliable operation with 0.5 mm (24 AWG) cables up to 25 m at 235 MHz - verified in lab conditions. No external calibration or I2C control is needed, making the TDA19977AHV/15C184 ideal for plug-and-play HDMI infrastructure.
Can TDA19977AHV/15C184 decode HBR, DST, and OBA audio streams?
Yes, TDA19977AHV/15C184 fully supports HBR (High Bit Rate), DST (Direct Stream Transfer), and OBA (One Bit Audio) streams per HDMI 1.3a. It extracts and demultiplexes HBR packets (e.g., Dolby TrueHD, DTS-HD Master Audio) up to 768 kHz, outputs six DSD channels for SACD, and handles IEC 61937-compliant compressed audio. The TDA19977AHV/15C184 includes a two-channel status decoder to read copyright, sampling frequency, and stream type directly from IEC 60958/61937 data.
What power supply requirements does TDA19977AHV/15C184 have?
TDA19977AHV/15C184 requires five separate supply rails: VDDH(3V3) and VDDH(1V8) for HDMI receiver circuitry, VDDC(1V8) for digital core, VDDO(3V3) for video port outputs, and VDDI(3V3) for digital inputs. All 3.3 V supplies tolerate ±5 % variation (3.135–3.465 V); 1.8 V supplies tolerate ±5 % (1.71–1.89 V). The TDA19977AHV/15C184 consumes 1.13 W at 1080p60 and drops to 1 mW in full power-down mode.
