PI3EQX1204-CZHE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX1204-C is a SAS3 ReDriver featuring four differential channels with linear equalization, supporting serial link speeds up to 12.5Gbps. It handles SATA Gen1/Gen2/Gen3, SAS2/3, and XAUI protocols while managing channel losses up to 34dB. The device operates on a 3.3V±0.3V supply voltage within an industrial temperature range of -40°C to 85°C. Configuration is achieved via pin strapping or I2C control, allowing independent adjustment of receiver equalization, output swing, and flat gain per channel.

Signal Buffers, Repeaters, Splitters FAQ

How is the device configured for operation?

The PI3EQX1204-C can be configured using either external pin strapping voltages or through an I2C interface, depending on the state of the ENI2C pin.

What is the maximum channel loss the device can handle?

The device is capable of handling up to 34dB of channel loss, which corresponds to approximately 42 inches of FR4 trace or 10 meters of SAS3 cable.

Does the device support multiple chips in a single system?

Yes, the device supports multiple chips through its I2C interface, which allows for 4-bit selectable address bits to configure unique addresses for each chip.
