PI2EQX6874ZFE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX6874ZFE is a 6.5Gbps low-power ReDriver designed for SAS2, SATA3, and XAUI applications. It features four lanes (eight differential channels) with programmable equalization, amplification, and de-emphasis controlled via an I2C interface. The device operates on a single 1.2V ± 5% supply voltage. Key electrical parameters include a typical active current of 95mA per channel, a standby current of 1mA, and a slumber current of 10mA per channel. It supports adjustable receiver equalization up to 13.8dB at 6Gbps and includes internal 50-Ohm input/output termination. The component is housed in a 56-contact TQFN package measuring 5mm x 11mm.

Signal Buffers, Repeaters, Splitters Feature Summary

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ZFE suffix against the manufacturer's latest documentation to confirm packaging details and compliance status. Confirm availability as the component may be subject to lifecycle changes. Ensure the ordering information matches the required 56-contact TQFN package dimensions and industrial temperature range specifications.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for high-speed serial link applications requiring signal integrity optimization over lossy mediums. Ensure the design accommodates the 1.2V supply requirement and utilizes the I2C interface for dynamic configuration of equalization and de-emphasis settings. Verify that the system architecture supports the differential CML input/output standards and the specified operating temperature range.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the Pericom/PI2EQX series of ReDrivers manufactured by Diodes Incorporated. It is specifically engineered to mitigate Inter-Symbol Interference (ISI) in high-speed data transmission environments. The device integrates both input equalization and output de-emphasis to optimize signal performance before and after the driver stage.

Signal Buffers, Repeaters, Splitters FAQ

How is the I2C configuration enabled or disabled?

Configuration is determined by the MODE pin state. When MODE is High, I2C is disabled and default pin-strapped values are used. When MODE is Low, programming of control registers via I2C is allowed.

What is the function of the PD# pin?

The PD# pin controls the power-down mode. When PD# is Low, the IC is disabled, and both input and output buffers go to a high-impedance state.

Can the device operate without I2C communication?

Yes. By setting the MODE pin High, the device operates using default configurations latched from the configuration input pins at power-on, such as default de-emphasis, swing, and equalizer settings.
