PI2EQX5964ZFE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX5964 is a low-power, PCIe 2.0 compliant signal redriver designed for high-speed data transmission. It supports up to 5.0Gbps data rates across four lanes or eight differential channels. The device operates on a single 1.2V ± 0.05V supply voltage and features programmable equalization, amplification, and de-emphasis controlled via I2C. It includes variable input/output termination, 1:2 channel broadcast, and loop-back modes. Operating temperatures range from -40°C to +85°C in a 56-contact TQFN package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable equalization and de-emphasis to optimize signal integrity over various physical mediums.
• Supports flexible configuration through I2C control, including adjustable output levels and electrical idle thresholds.
• Integrates power management capabilities with standby mode and individual output control.

Signal Buffers, Repeaters, Splitters Applications

• PCIe 2.0 cable extensions
