PI2EQX6811ZDE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX6811 is a low-power, single-port SATA Gen 3i and SAS2 ReDriver manufactured by Diodes Incorporated. It features two 6Gbps differential signal pairs with 100Ω Differential CML I/Os. The device operates on a 1.5V ± 5% supply voltage within an industrial temperature range of -40°C to 85°C. Key electrical parameters include adjustable receiver equalization from 0 to 18dB, output pre-emphasis control from 0 to 6dB, and swing control up to 1200mV. Power consumption varies significantly based on mode: typical auto-slumber mode draws 22.5mW, while power-down standby mode consumes only 15µW.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports SATA Gen 3i and SAS2 standards with automatic HDD rate detection for optimized output settings.
• Provides pin strap or I2C programmable equalization and output emphasis to reduce inter-symbol interference.
• Includes input signal level detect and squelch functions for each independent channel.
• Features termination detect indication via I2C to enable power-saving modes when loads are connected.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Check for any recent product change notifications (PCN) that might affect pin compatibility or material composition before finalizing procurement plans.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for applications requiring signal integrity restoration over backplanes or distant data pathways in SATA and SAS environments. Ensure the design supports the required 1.5V supply rail and accommodates the 20-TQFN package dimensions. Verify that the system architecture can utilize I2C control for dynamic adjustment of equalization and emphasis settings to optimize performance across varying physical mediums.

Signal Buffers, Repeaters, Splitters Part Context

The PI2EQX6811 belongs to the PI2EQX series of ReDrivers designed for high-speed serial interfaces. It addresses signal degradation issues common in storage and server architectures by providing active signal conditioning. This component is part of Diodes Incorporated's portfolio following their acquisition of Pericom, maintaining the original functional specifications and branding associated with the PI2EQX line.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct substitutes may include other single-port 6Gbps ReDrivers from Diodes Incorporated or competitors offering similar SATA/SAS support. Verify pinout compatibility and I2C register mapping if replacing with devices from different manufacturers. Ensure equivalent power consumption profiles and thermal characteristics match the original design constraints.
