The SY58023U is a 2.5V/3.3V precision, high-speed, fully differential CML 2 x 2 crosspoint switch. The SY58023U is optimized to provide two identical output copies with less than 20ps of skew and ultra-low jitter. It can route clock signals as fast as 6GHz or data up to 10.7Gbps. The differential input includes Micrel's unique, 3-pin input termination architecture that allows the SY58023U to directly interface to LVPECL, LVDS, and CML differential signals (AC- or DC-coupled) as small as 100mV (200mVpp) without any level-shifting or termination resistor networks in the signal path. The CML outputs features 400mV typical swing into 50 loads, and provide an extremely fast rise/fall time guaranteed to be less than 60ps. The SY58023U operates from a +2.5V 5% supply or +3.3V 10% supply and is guaranteed over the full industrial temperature range (40C to +85C). For applications that require high speed dual CML switches, consider the SY58024U. The SY58023U is part of Micrel's high-speed, Precision Edge product line.
