PI3HDX1204B1ZHIEX

Specialized Overview

The PI3HDX1204B1ZHIEX is a four-channel HDMI 2.0 compliant limiting-type ReDriver designed for 6.0 Gbps data rates. It features programmable high equalization up to +22.2 dB at 3 GHz, output swing control, and de-emphasis settings. The device supports Dual-Mode DisplayPort Level Shifting and offers double the jitter performance compared to conventional CMOS-process ReDrivers. It operates on a single 3.3V supply within an industrial temperature range of -40°C to 85°C. Configuration is achieved via pin-strapping or I2C programming, allowing independent channel optimization for various physical media.

Specialized Feature Summary

• Supports Dual-Mode DP HBR3 to HDMI 2.0 level shifting
• Provides 16-step input equalization up to +22.2 dB at 3 GHz
• Features built-in channel activity detector with selectable termination
• Offers independent per-channel configuration for equalization, swing, and de-emphasis

Specialized Applications

• Notebooks, Desktops and AIO PCs
• HDMI Active Cables
• Internal Board Connection Inside Video Systems

Specialized Procurement Notes

Verify the specific ZHIEX suffix indicates the industrial temperature grade (-40°C to 85°C) as distinct from commercial variants. Confirm the package code corresponds to the 42-pin TQFN (3.5x9mm) form factor. Ensure compatibility with the required 3.3V power supply and I2C bus voltage levels before integration into the design.

Specialized Selection Notes

Select this component when designing systems requiring HDMI 2.0 signal integrity over long traces or active cables. The device is suitable for compensating high insertion loss in TMDS transmission lines. Consider its dual-mode DisplayPort capabilities if the application involves converting DP++ signals to HDMI outputs. Verify that the available equalization steps match the expected trace losses in the target PCB layout.
