PI2EQX6814NJEX

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX6814 is a 6.5Gbps low-power ReDriver™ designed for SAS2, SATA, and XAUI applications. It features four lanes supporting eight differential channels with independent configuration capabilities. The device provides programmable equalization, amplification, and de-emphasis to optimize signal integrity across various physical mediums by reducing inter-symbol interference. Configuration is managed via pin strapping or an I2C interface with 3.3V tolerant inputs. It operates on a single 1.2V ± 5% supply voltage and includes automatic slumber mode power savings alongside a standby mode. The component supports mux/demux and loop-back features, fully supports Out-of-Band (OOB) signaling, and operates within an industrial temperature range of -40°C to 85°C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific package variant and ordering suffix against the manufacturer's current datasheet before procurement. Confirm that the application environment remains within the specified industrial temperature range and supply voltage tolerances. Ensure I2C bus compatibility regarding address bits and logic levels. Check for any product change notifications that may affect pinout or electrical characteristics.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring signal regeneration for SAS2, SATA, or XAUI interfaces at speeds up to 6.5Gbps. Consider its independent channel configuration if asymmetric lane requirements exist. Evaluate the need for I2C control versus pin-strapped configuration based on system flexibility needs. Ensure the PCB layout accommodates the LBGA package dimensions and thermal requirements.
