SY56020RMG-TR

Clock Buffers, Drivers Overview

The SY56020RMG-TR is a low-voltage CML 1:4 fanout buffer with input equalization, operating from a 2.5V ±5% core supply and a 1.2V/1.8V/2.5V ±5% output supply. It processes clock signals up to 4.5GHz or data patterns up to 6.4Gbps. The device features a unique 3-pin input termination architecture for direct CML interfacing without external level-shifting. AC performance guarantees include less than 280ps propagation delay, under 15ps within-device skew, and less than 90ps rise/fall times. It operates over the industrial temperature range of –40°C to +85°C.
