PI2EQX3211BHE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX3211BHE is a low-power, signal re-driver manufactured by Diodes Incorporated (formerly Pericom). It features two independent 3.2Gbps differential channels designed for SATA applications. The device operates within a supply voltage range of 1.5V to 1.8V and consumes approximately 100mW per channel during active operation. It utilizes 100-Ohm differential CML I/Os with integrated equalization controlled by EQA and EQB pins. Key electrical characteristics include a typical latency of 2.0 ns, an output voltage swing of 400mV to 750mV peak-to-peak, and input signal detection thresholds between 50mV and 200mV. The component is housed in a 20-lead SSOP package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable receiver equalization using two select bits to optimize performance across various physical mediums and reduce inter-symbol interference.
• Integrates input signal level detection and output squelch functions for each channel to manage signal integrity and power states.
• Supports flow-through pinout architecture with independent channel operation for connecting protocol ASICs to switch fabrics or backplanes.

Signal Buffers, Repeaters, Splitters Applications

• SATA serial link signal re-driving
• Backplane signal extension
• Distant data pathway signal conditioning

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'H' corresponds to the tape and reel packaging format as documented in the datasheet. Confirm that the manufacturer designation has transitioned from Pericom Semiconductor to Diodes Incorporated to ensure accurate sourcing and documentation alignment. Check for RoHS compliance status regarding the 'E' suffix indicating lead-free and green material composition.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring 3.2Gbps data rates with low power consumption constraints. Ensure the design environment supports a 1.5V to 1.8V supply voltage and accommodates the 20-lead SSOP footprint. Consider the adjustable equalization settings if significant inter-symbol interference is expected from the transmission medium.
