PI3HDX12211AZHEX

Signal Buffers, Repeaters, Splitters Overview

The PI3HDX12211AZHEX is a four-channel HDMI 2.1 linear redriver designed to extend signal pathways by reducing inter-symbol interference. It supports data rates up to 12 Gbps and provides programmable linear equalization, output swing, and flat gain via pin strapping or I2C control. The device operates on a single 3.3V ±0.3V supply within an industrial temperature range of -40°C to +85°C. Each channel dissipates 220mW with a 1200mVpp output swing. It features conditional pullup or high-impedance outputs, back current leakage protection (Ioff), and a 3-bit selectable I2C address.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'ZH' corresponds to the 42-contact TQFN package with conditional pullup or high-impedance options as documented in the manufacturer's datasheet. Confirm that the 'E' designation indicates lead-free and green compliance status. Ensure procurement channels provide valid traceability documentation for RoHS 2 and RoHS 3 directives. Cross-reference the part number against the latest product brief to confirm active status and availability of technical support resources.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending HDMI 2.1 signals over PCB traces requiring low equalizer options for short pre-channels. Choose based on the requirement for 1200mVpp output swing and 220mW per-channel power dissipation. Evaluate the need for I2C configurability versus fixed pin-strapping settings. Consider the industrial temperature range (-40°C to +85°C) for robust environmental operation. Verify compatibility with 100Ω differential CML data interfaces.
