草榴社区 Low Voltage Differential Signaling (LVDS) IO

Select Your IO Library IP by Foundry & Process Technology

草榴社区 Low Voltage Differential Signaling (LVDS) IO library is a high-frequency interface that uses differential signals for data transmission. A few typical LVDS IO applications are in display monitors, printers, high-speed clock transfers, and high-speed SERDES. 草榴社区 LVDS IO library is used to build an LVDS-based interface for high-speed interconnect applications. This library is designed to optimize IO performance with a core voltage of 0.75 V and supports an IO supply voltage of 1.2V/1.5 V. The library contains a transmitter, a receiver, and a bandgap reference circuit that is used to supply the current reference for the transmitter/receiver. The LVDS IO library is compatible with the IEEE standard 1596.3-1996 and TIA/EIA - 644 -A. Key Features are:

Maximum operating speed: up to 3.4GBPS
