PI3EQX1204-BZHEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX1204-BZHEX is a 3.3V, 12.5Gbps four-channel SAS3/SAS2/SATA3/XAUI ReDriver manufactured by Diodes Incorporated. It operates within an industrial temperature range of -40°C to +85°C and supports up to 3.6V supply voltage. The device features four 100-Ohm differential CML data I/Os and provides programmable equalization, output swing, pre-shoot, and de-emphasis via pin strapping or I2C control. It includes per-channel activity detection with selectable input termination between 50Ω to VCC and 200Ω to VCC. The component is housed in a 42-contact TQFN package measuring 9mm x 3.5mm.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the manufacturer designation as Diodes Incorporated, which acquired Pericom Semiconductor. Confirm the specific suffix ZHEX corresponds to the required tape and reel packaging quantity. Ensure the datasheet matches the 42-contact TQFN form factor and that the I2C address settings align with system requirements before finalizing procurement orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing high-speed SAS or SATA backplanes requiring signal integrity restoration. The choice depends on the need for independent channel equalization and the availability of I2C or pin-strapped configuration methods. Verify that the 3.3V supply and industrial temperature range meet the platform specifications.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3EQX1204 series of ReDrivers designed for high-speed serial interfaces. It serves as a bridge to extend signal pathways across distant data routes in storage and server architectures. The device addresses signal degradation issues common in SAS3 and SATA3 environments by actively compensating for inter-symbol interference.
