The SY58023U is a 2.5V/3.3V precision, high-speed, fully differential CML 2x2 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 50Ω 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 (-40°C to +85°C). 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.
