PI3EQX1204-CZHEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX1204-CZHEX is a 4-channel ReDriver designed for serial links up to 12.5Gbps, supporting SAS3 and 10GbE protocols. It mitigates inter-symbol interference through programmable linear equalization, output swing adjustment, and flat gain control. The device operates on a single 3.3V supply within an industrial temperature range of -40°C to +85°C. It features CML differential I/Os with internal termination options and offers flexible configuration via pin strapping or I2C interface. Packaged in a 42-contact TQFN (9mm x 3.5mm), it provides independent channel programming for optimized signal integrity across various physical mediums.
