PI3EQX6801A

Description

The PI3EQX6801A is a low power, 1.5V/3.3V, 6.5Gbps, SATA/SAS signal ReDriver™. The device provides programmable equalization, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference.

PI3EQX6801A supports two 100Ω Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a backplane, or to extend the signals across other distant data pathways on the user’s platform.
The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver.
A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independently.
When the channels are enabled (x_EN#=0) and operating, that channels input signal level (on xI+/-) determines whether the output is active. If the input signal level of the channel falls below the active threshold level (Vth-) then the outputs are driven to the common mode voltage.
Each lane can be powered-down if x_EN# =1, and when A_EN# and B_EN# are both high, the device enters a low power standby mode.
