PI2EQX6874ZFEX

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX6874ZFEX is a 6.5Gbps low-power ReDriver designed for SAS2, SATA3, and XAUI applications. It features four lanes with eight differential CML channels, providing programmable equalization, amplification, and de-emphasis via I2C control to mitigate inter-symbol interference. The device operates on a single 1.2V ± 5% supply voltage. Key electrical parameters include an active current of 900mA (typical) at full load, a slumber current of 10mA per channel, and a standby current of 1mA. It supports adjustable receiver equalization up to 13.8dB and transmitter amplitude settings ranging from 0.3V to 1.3V differential peak-to-peak.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix ZFE against the manufacturer's official documentation to confirm packaging details and compliance status. Confirm availability as distribution data may indicate limited stock or end-of-life status. Ensure the ordering information matches the exact component requirements for your design.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing high-speed serial links requiring signal integrity enhancement for SAS, SATA, or XAUI protocols. Consider the 56-contact TQFN package dimensions and the requirement for a 1.2V power supply. Evaluate the need for I2C configurability versus fixed pin-strapping options based on system flexibility requirements.
