PI3DPX1207B1ZHIEX

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1207B1ZHIEX is a linear ReDriver supporting USB Type-C port operation for 10Gbps USB 3.2 and 8.1Gbps DisplayPort 1.4 standards in industrial temperature ranges. It features a 4:4 channel configuration with integrated USB/DP crossbar switch support, transparent link training, and ultra-low signal latency. The device includes programmable CLTE equalization, flat gain, and output swing linearity controls to compensate channel loss and remove ISI jitter. Built-in AUX listener enables automatic channel configuration and power saving. Operating voltage is 3.3V, data rate is 10Gbps across 4 lanes, max output swing is 1200mV, controlled via I2C or pin-strapping, operating from 0°C to +85°C in a 42-pin TQFN package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZHIEX confirms the industrial temperature range of 0°C to +85°C as documented in the datasheet. Confirm the package code corresponds to the 42-pin Very Thin Quad Flat No-Lead (TQFN) dimensions of 3.5 x 9 mm. Ensure procurement matches the exact part number to guarantee correct operational parameters and interface compatibility.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when an industrial temperature range up to 85°C is required for USB Type-C applications. Choose between I2C or pin-strapping control based on system design flexibility needs. Verify that the 4-channel configuration aligns with the host controller's lane requirements for both USB 3.2 and DisplayPort 1.4 signals.

Signal Buffers, Repeaters, Splitters Part Context

The PI3DPX1207B1ZHIEX belongs to the PI3DPX1207B1 series of linear Redrivers designed for USB Type-C ports. It serves as an enhanced version supporting higher speed standards compared to previous generations. The ZHIEX variant specifically denotes the industrial temperature grade within the product family, distinguishing it from commercial variants like the ZHEX.

Signal Buffers, Repeaters, Splitters Replacement Considerations

PI3DPX1207B1ZHEX offers identical electrical specifications but operates within a commercial temperature range of 0°C to +70°C instead of the industrial range.
