PI2EQX6812ZHEX

New Product Databrief PI2EQX6812 6.5Gbps 2-Lane (4-channel)SAS2/SATA/XAUI ReDriver™ with Equalization & De-emphasis Pericom Semiconductor’s PI2EQX6812 is a low power, SAS2, 2-lane (4 differential channels) SATA, XAUI signal ReDriver™. The device provides programmable equalization, amplification, and de-emphasis by either pin strapping option or I2C Control, to optimize performance over a variety of physical mediums by reducing Inter-symbol interference. PI2EQX6812 supports four 100-Ohm Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a backplane, or extends the signals across other distant data pathways on the user’s platform. Features • Up to 6.5Gbps SAS2/SATA/XAUI ReDriver™ • Supporting 4 differential channels or 2 lane • Independent channel configuration • Pin strap and I2C configuration controls (3.3V Tolerant) • Adjustable receiver equalization • Adjustable transmitter amplitude and de-emphasis The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver, whereas the integrated de-emphasis circuitry provides flexibility with signal integrity of the signal after the ReDriver. • Adjustable input threshold level In addition to providing signal re-conditioning, Pericom’s PI2EQX6812 also provides power management Stand-by mode operated by a Power Down pin, or through I2C register.
