IT6633E-P Three-to-One HDMI v.1.3 Active Switch | Dark Mode Support

IT6633E-P 3-to-1 HDMI v1.3 Active Switch with Dark Mode Support

Experience superior HDMI switching with the IT6633E-P — a three-to-one HDMI v1.3 active switch IC. Designed for optimal performance, supports signaling rates up to 2.25 Gbps and introduces the Dark Mode feature. With software mode operation and two-wire serial interface PCSCL / PCSDA, the IT6633E-P offers flexible control options for AV equipment repair / OEM production.

Upgrade from traditional passive switches to HDMI active switching — the IT6633E-P actively equalizes incoming TMDS data, ensuring outstanding signal quality regardless of input quality. Embedded EDID RAM eliminates the need for external EDID ROM, reducing BOM cost. Integrated HDP resistor and HPD switch streamline connectivity and detection.

Key Features

• Three-to-one HDMI v1.3 active switching with software-mode control.
• Up to 2.25 Gbps serial data rates.
• Dark Mode feature for low-power standby behavior.
• Active TMDS equalization for improved signal quality across input variations.
• Embedded EDID RAM — eliminates external EDID ROM.
• Integrated HDP resistor + HPD switch for connectivity / detection.
• Human body model ESD protection up to ±8 kV on all TMDS differential input pins.
• Disconnectable input terminals with automatic impedance calibration.
• Adaptive input equalization supports both long and short cables.

FAQ — IT6633E-P HDMI Switch IC

Q: HDMI v1.3 — is that still relevant?
A: HDMI v1.3 supports 1080p / 60Hz at full resolution — still standard for many AV receivers, digital signage, and embedded video systems. For 4K / HDR applications, newer HDMI versions (2.0 / 2.1) are required. The IT6633E-P fits legacy / mid-range AV equipment.

Q: What's "active" vs "passive" HDMI switching?
A: Passive switches simply route the signal through analog selectors — quality limited by cable impedance and input variation. Active switches like the IT6633E-P actively re-equalize the TMDS data, restoring signal quality across input variations. Active is significantly better for long-cable or weak-source scenarios.

Q: What does Dark Mode do?
A: Dark Mode is a low-power standby state where the switch reduces power consumption while maintaining connectivity awareness. Useful for energy-efficient AV product designs where the switch isn't always actively routing video.
