The PI90LV211QEX is a 1:1 LVDS (Low Voltage Differential Signaling) Repeater/Redriver designed by Pericom. It is engineered to extend the transmission distance and improve signal integrity of LVDS signals in various high-speed data communication applications. This device is commonly used to overcome signal degradation issues in long cable runs or backplane environments.

Applications

• Long cable runs in data centers
• Backplane communication in servers
• Video signal distribution systems
• Industrial automation
• Telecommunications equipment

Features

• 1:1 LVDS Repeater/Redriver
• Data rates up to 3.125 Gbps
• Low power consumption
• 3.3V power supply operation
• Adjustable equalization
• Pre-emphasis feature
• Small form factor package

Benefits

• Signal integrity improvement: Redrives and reshapes LVDS signals to improve signal quality and extend transmission distance.
• High-speed data transmission: Supports data rates up to 3.125 Gbps, enabling high-bandwidth communication.
• Adjustable equalization: Compensates for signal attenuation and dispersion caused by long cable runs or backplane traces.
• Pre-emphasis feature: Enhances signal transitions to overcome inter-symbol interference (ISI).
• Low power consumption: Minimizes power consumption, making it suitable for energy-efficient applications.

The PI90LV211QEX operates by receiving an LVDS signal, applying equalization and pre-emphasis to compensate for channel losses, and then retransmitting the signal with improved signal integrity. The adjustable equalization allows the device to be optimized for different cable lengths and backplane characteristics. The pre-emphasis feature helps to overcome ISI, which can degrade signal quality at high data rates. The device is available in a small form factor package, making it suitable for space-constrained applications. It operates on a 3.3V power supply.
