This paper presents the design and the implementation of input/output (I/O) interface circuits for 2.5 Gbps operation in a 3.3V 0.35um CMOS technology. Due to the differential transmission technique and low voltage swing, LVDS(low-voltage differential signaling) has been widely used for high speed transmission with low power consumption. This interface circuit is fully compatible with the LVDS standard. The LVDS proposed in this paper utilizes a telescopic amplifier. This circuit is operated up to 2.3 Gbps. The circuit has a power consumption of 25. 5mW. This circuit is designed with Samsung $0.35{\mu}m$ CMOS process. The validity and effectiveness are verified through the HSPICE simulation.
