IT6569: High-Performance 4-Lane DP1.4 to HDMI 2.1 Converter for 8K and High-Refresh-Rate Displays

As high-resolution, multi-display, and high-frame-rate applications continue to grow, system designers face increasing demands for reliable DP-to-HDMI conversion. Achieving high bandwidth, low latency, stable output, and easy system integration has become essential across PCs, docking stations, monitors, and embedded platforms.
To address these needs, ITE Tech. Inc. presents the IT6569-a highly integrated DisplayPort-to-HDMI converter combining DP1.4 RX and HDMI 2.1 TX, designed to support next-generation display formats including 8K, 4K240, and 4K120. It enables seamless cross-interface connectivity with high image quality and robust performance.

DP 1.4a with 4-Lane HBR3 Input for High-Bandwidth Video Reception

The IT6569 supports DP 1.4a input at up to 8.1Gbps × 4 lanes (HBR3) and incorporates a DSC 1.2a decoder to efficiently handle ultra-high-resolution video streams. Supported resolutions include:

• 4K 240Hz 4:4:4 (with DSC)
• 4K 120Hz 4:4:4 (FRL)
• 8K 30Hz 4:4:4 (FRL)
• 8K 60Hz 4:2:0 (FRL)

It supports a wide range of VESA and CEA timing formats, making it ideal for high-refresh-rate monitors, docking devices, and multi-display expansion products.

HDMI 2.1a Output Ensures High Compatibility and Stable Image Quality

The HDMI TX supports both FRL and TMDS modes and complies with HDMI 2.1a / HDCP 1.4 / HDCP 2.3 / DVI 1.0, providing high signal integrity and broad device compatibility.
Key output capabilities include:

• Up to 12Gbps FRL mode
• Support for 36-bit deep color
• Full backward compatibility with earlier HDMI and DVI displays

The result is a robust and flexible output path suitable for consumer, industrial, and professional visual systems.

Comprehensive Audio Format Support: From LPCM to High-Bit-Rate Audio

Beyond video conversion, IT6569 features strong audio processing capabilities:

• 8-channel LPCM (32-192kHz / 16-24 bits)
• Up to 768kHz HBR audio in DP-to-HDMI pass-through mode
• Audio extraction via I²S / SPDIF

This makes IT6569 suitable for applications requiring synchronized high-quality audio output.

VRR Support for Tear-Free, Low-Latency Visual Performance

The IT6569 converts DisplayPort Adaptive Sync into HDMI 2.1 Variable Refresh Rate (VRR), enabling:

• Tear-free motion
• Lower latency
• Smooth dynamic refresh-rate transitions

It is ideal for gaming monitors, docking stations, and high-speed visualization equipment.

Highly Integrated Architecture with Built-In MCU, Flash, and InfoBlock

To simplify system design, the IT6569 integrates:

• An internal MCU
• On-chip Flash memory
• InfoBlock communication interface
• Twelve GPIO pins

It requires no external MCU, Flash, or HDCP ROM, reducing BOM cost, PCB area, and development complexity.
HDCP keys are pre-programmed per device, enabling faster compliance and easier mass-production integration.

Versatile Applications Across High-Resolution and Multi-Interface Systems

The IT6569's flexible architecture and wide compatibility make it ideal for:

• WOA PCs, notebooks, and desktops with DP-to-HDMI output needs
• Docking stations and USB-C hubs
• Industrial and embedded display platforms
• OPS modules and commercial signage displays
• HDMI monitors, TVs, and ProAV sink devices

IT6569: The Flexible Core for High-Resolution, Cross-Interface Video Output

With its high integration, broad compatibility, and support for ultra-high-resolution output, the IT6569 allows system designers to deliver stable, smooth, and high-quality video experiences within compact system constraints.
From gaming and commercial displays to industrial and multimedia systems, the IT6569 provides a dependable and efficient DP-to-HDMI conversion solution.
