Product details
Overview
TDA19998HL/C1,557 from NXP Semiconductors is a 4:1 HDMI 1.4a-compliant switch IC for high-speed TMDS signal routing in AV receivers and home theater systems. It supports four independent HDMI inputs (up to 2.25 Gbit/s), embedded EDID memory per input, auto-adaptive equalization for up to 30 m AWG24 cables, and F3 fast-switching technology preserving HDCP 1.4 encryption during port changes.
For engineers reviewing the TDA19998HL/C1,557 datasheet, TDA19998HL/C1,557 pinout, TDA19998HL/C1,557 application, or TDA19998HL/C1,557 equivalent, key selection criteria include HDMI 1.4a compliance, Deep Color support (36-bit at 1080p60), I2C-bus controllability (400 kHz), integrated 50 Ω termination, and LQFP100 package compatibility with TDA19997/TDA9996.
Technical Context
The TDA19998HL/C1,557 implements a fully auto-adaptive input equalizer supporting 20 m AWG26 at 2.25 Gbit/s and 30 m AWG24 at 1.5 Gbit/s, with no external tuning required. Its F3 switching architecture detects HDCP A0 state before reconfiguration to avoid stream interruption or decryption loss when changing between HDMI inputs.
It integrates five DDC-bus interfaces - four per HDMI input plus a dedicated fifth for VGA or SoC secondary HDMI - with level-shifting, master-switch arbitration, and digital lock-up protection. Power management includes EDID-only, Idle, and Power-down modes, with activity detection enabling automatic output activation and power reduction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDA19997HN/C1,557 | Pin-compatible predecessor; lacks F3 switching - requires HDCP reset on input change causing brief stream interruption | Suitable for cost-sensitive designs where zero-latency switching is not required | Select TDA19997HN/C1,557 only if HDCP continuity during switching is not mandatory |
| TDA9996HN/C1,557 | Same pinout and I2C address; supports only 2 HDMI inputs; no fifth DDC-bus input; lower max data rate (1.65 Gbit/s) | Targeted at entry-level AV receivers with fewer sources and no VGA hybrid requirement | Choose TDA9996HN/C1,557 when system needs only two HDMI inputs and simpler DDC routing |
Compared with TDA19998HL/C1,557, TDA19997HN/C1,557 sacrifices HDCP continuity for lower cost, while TDA9996HN/C1,557 trades input count and bandwidth for reduced complexity - making TDA19998HL/C1,557 the sole option for 4-input, F3-enabled, VGA-hybrid HDMI routing.

FAQ
What HDMI standards does the TDA19998HL/C1,557 support?
The TDA19998HL/C1,557 complies with HDMI 1.4a, DVI 1.0, EIA/CEA-861D, and HDCP 1.4 specifications. It supports Deep Color up to 36-bit per pixel, all Data Island packets including 3D InfoFrames, and ATC/Rx and ATC/Tx eye diagram compliance for 1080p60 36-bit video. The TDA19998HL/C1,557 does not decode Deep Color or Data Island content but forwards it transparently.
How does the F3 switching technology in the TDA19998HL/C1,557 differ from standard HDMI switching?
F3 technology in the TDA19998HL/C1,557 detects the HDCP A0 authentication state before switching inputs, avoiding unnecessary HDCP resets. This enables instantaneous, glitch-free port changes while preserving encrypted HDMI output continuity - unlike standard switches such as TDA19997HN/C1,557 that interrupt the stream during re-authentication. The TDA19998HL/C1,557 achieves true zero-delay switching without compromising security.
Can the TDA19998HL/C1,557 operate without +5 V from HDMI sources?
Yes. The TDA19998HL/C1,557 can be powered for EDID and DDC functionality via the dedicated AUX_5V pin, enabling operation with HDMI sources that omit the +5 V supply - common in passive cabled connections. When AUX_5V is active, EDID memory remains accessible and retainable even if no HDMI input provides +5 V, ensuring reliable plug-and-play behavior across diverse source types.
What is the purpose of the R12K pin on the TDA19998HL/C1,557?
The R12K pin on the TDA19998HL/C1,557 controls internal 50 Ω termination resistors for HDMI inputs. It requires an external 12 kΩ ±1 % pull-down resistor to ground. When asserted via I2C or when RXx_HPD is LOW, the termination can be disconnected from the 3.3 V supply to remove common-mode voltage - essential for compliance with HDMI 1.4a termination requirements and signal integrity optimization.
Does the TDA19998HL/C1,557 support HDMI Ethernet and Audio Return Channel (HEAC)?
The TDA19998HL/C1,557 is HEAC-ready: its HPD outputs are biased to 4 V to interface directly with external HEAC modules. However, the TDA19998HL/C1,557 itself does not implement Ethernet or ARC functionality - it provides the necessary electrical interface and signal conditioning for companion HEAC PHY devices, enabling system-level HEAC integration without modifying the core HDMI switching path.
