The PI2EQX4401DZFEX is an integrated circuit (IC) component developed by Pericom Semiconductor Corporation. It is a powerful redriver/repeater with a wide range of features that make it suitable for various high-speed signal applications. Let's delve into its key features and overall overview:
1. Introduction:
The PI2EQX4401DZFEX belongs to the PCIe redriver/repeater family. It is designed to enhance signal integrity while maintaining optimal performance in high-speed serial link applications. It primarily focuses on USB 3.2 Gen 2 (10Gbps) and USB4 (20Gbps) applications, but it can also support PCIe (up to Gen 3) and SATA (up to 6Gbps) signals.
2. Signal Integrity Enhancement:
The IC incorporates Adaptive Input Equalization (AIE) technology, which compensates for channel losses and improves the signal quality. This feature allows for extended signal reach without sacrificing performance, ensuring reliable data transmission.
3. Equalization and De-emphasis:
The device provides selectable linear equalization and de-emphasis that can be configured to optimize signal integrity over various PCB traces, cables, or interconnect media. The equalization and de-emphasis settings can be adjusted to accommodate different link lengths and transmission environments, thus enabling flexibility in system designs
