PI2EQX3232AZDE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX3232AZDE is a low-power signal Re-Driver manufactured by Diodes Incorporated, originally designed by Pericom Semiconductor. It supports data rates up to 3.2Gbps on each lane and features four 100-Ohm Differential CML I/Os. The device provides programmable equalization, amplification, and de-emphasis to optimize performance over various physical mediums by reducing Inter-Symbol Interference (ISI). It operates within a VDD range of 1.8V +/-0.1V and consumes approximately 100mW per channel. The component is housed in a 48-contact TQFN package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the manufacturer designation as Diodes Incorporated while noting the original design origin from Pericom Semiconductor. Confirm the specific ordering suffix 'ZDE' corresponds to the Pb-free & Green 48-contact TQFN package variant. Ensure compatibility with the 1.8V supply voltage requirement and check for any product change notifications or lifecycle status updates prior to procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring signal regeneration for SATA or SAS interfaces at speeds up to 3.2Gbps. Consider its low power consumption of 100mW per channel and the need for external configuration via SEL pins for equalization and de-emphasis settings. Ensure the PCB layout accommodates the 48-contact TQFN package and provides adequate thermal dissipation for the exposed pad.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI2EQX series of serial Re-Drivers. It is functionally similar to other devices in the family but specifically tailored for 3.2Gbps operation. The 'A' suffix typically denotes a specific revision or pin-compatible update within the series, while 'ZDE' specifies the tape and reel packaging format.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct replacements may include other PI2EQX series parts with compatible pinouts and electrical characteristics. Verify that any substitute supports the required 3.2Gbps data rate and 1.8V operating voltage. Check for equivalent package dimensions and thermal requirements to ensure mechanical fit.
