This DisplayPort receiver also supports MCCS and CEC tunneling over AUX channel.

The built-in HDMI transmitter is a high-performance HDMI 2.1 transmitter, fully compliant with HDMI 2.1a, HDCP 1.4/2.3 and backward compatible with DVI 1.0 specifications. This HDMI transmitter can support color depth up to 36 bits ( 12 bits/color ) and ensures robust transmission of high-quality uncompressed video content. Aside from the various video output formats supported, this HDMI transmitter also support 8-channels digital audio, with sampling rate up to 192 kHz and sample size up to 24 bits, and HBR audio.

With embedded MCU and Flash, IT6569FN is easy to program. Customers need no external Flash and MCU, which can reduce the BOM cost and board size.

Each IT6569FN comes preprogrammed with a unique HDCP key, in compliance with 1.3/2.3 –Amendment for DisplayPort, rev1.0 and HDCP 1.4/2.3 –HDMI compliance standard to ensure secure transmission of high-definition content. Users of the IT6569FN do not need to purchase any HDCP keys or ROMs.

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.

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.

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.

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.

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.

To simplify system design, the IT6569 integrates:

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