PI3EQX6801AZDEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX6801AZDEX is a low-power, single-port SATA/SAS signal ReDriver manufactured by Diodes Incorporated. It features two 6.5Gbps differential channels with 100Ω CML I/Os and supports both 1.5V and 3.3V supply voltages. The device provides programmable equalization ranging from 0 to 16 dB, continuous step output swing adjustment up to 1.2V pk-to-pk, and pre-emphasis control. It includes input signal level detection, auto HDD rate detection, and an auto slumber mode consuming 22.5mW typical power. Packaged in a 20-contact TQFN (4x4mm), it operates within an industrial temperature range of -40°C to 85°C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the ordering suffix 'ZDEX' corresponds to the 20-lead TQFN package and tape/reel packaging format as specified in the manufacturer's documentation. Confirm that the component meets RoHS 3 compliance standards required for your assembly process. Ensure the design accommodates the specific thermal characteristics and pin configuration detailed in the datasheet.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when signal integrity degradation requires active re-driving across backplanes or distant data pathways. Choose between 1.5V or 3.3V operation based on system power architecture, noting that performance characteristics remain consistent across both voltage options. Consider the analog configuration pins for fine-tuning equalization and swing levels to match specific PCB trace losses.
