SY58040UMY

Product Summary

The SY58040UMY is a low jitter, low skew, high-speed 4×4 crosspoint switch optimized for precision telecom and enterprise server/storage distribution applications. The SY58040UMY distributes clock frequencies from DC to 4GHz, and data rates to 5Gbps guaranteed over temperature and voltage. The SY58040UMY differential input includes Micrel’s unique, 3-pin input termination architecture that directly interfaces to any differential signal (AC or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path. The applications of the SY58040UMY include Data communication systems, All SONET/SDH data/clock applications, All Fibre Channel applications, All Gigabit Ethernet applications.
