PI3HDX1204CZHEX

Specialized Overview

The PI3HDX1204CZHEX is a four-channel linear redriver designed for HDMI 2.0 applications, supporting data rates up to 6Gbps. It operates on a single 3.3V ±0.3V supply and features programmable linear equalization, output swing, and flat gain via I2C or pin control. The device provides 7dB gain compensation at 3GHz and dissipates 220mW per channel with a 1200mVpp output swing. It supports dual-mode DisplayPort level shifting and includes back current leakage protection. Packaged in a 42-contact TQFN, it functions within an industrial temperature range of -40°C to +85°C.

Specialized Feature Summary

• Supports non-blocking linear redriver operation for 6Gbps HDMI 2.0 signals through configurable I2C or pin strap settings.
• Provides independent channel configuration for receiver equalization, output swing, and flat gain to optimize signal integrity across various physical mediums.
• Enables transparent link training, rate detection, and coding while supporting dual-mode DisplayPort HBR3 to HDMI 2.0 level shifting.

Specialized Applications

• Laptop and Desktop PC
• Gaming Console
• DTV and Set-top-Box
• Docking Station and Peripherals

Specialized Procurement Notes

Verify the specific ordering suffix ZHEX confirms the tape and reel packaging format as indicated in the manufacturer's documentation. Confirm that the component meets RoHS 3 compliance and halogen-free requirements for your assembly process. Ensure the I2C address bits are correctly configured if multiple devices share the same bus. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Specialized Selection Notes

Select this component when designing systems requiring low equalizer options for short prechannel distances. It is suitable for extending signals across distant pathways where inter-symbol interference must be reduced. Consider its dual-mode DisplayPort capability if interfacing with DP sources. Verify that the 3.3V supply voltage aligns with your platform's power distribution network.

Specialized Part Context

This part belongs to Diodes Incorporated’s ReDriver family, specifically engineered for high-speed interface signal conditioning. It complements other HDMI and DisplayPort interface solutions by providing active signal regeneration. The PI3HDX1204C variant focuses on HDMI 2.0 standards, distinguishing itself from higher-rate models like the PI3EQX series used for SAS or PCIe applications.

Specialized Replacement Considerations

Check for direct substitutes within the PI3HDX1204 series, such as the PI3HDX1204B1ZHEX, ensuring package and electrical parameters match. Verify backward compatibility with HDMI 1.4 if required. Consult the manufacturer for automotive-grade alternatives if AEC-Q100 qualification is necessary.
