The SY56034AR is a fully differential, low voltage 1.2V/1.8V/2.5V CML 2:6 (2+4) MUX with crosspoint capability. The SY56034AR can process clock signals as fast as 5GHz or data patterns up to 6.4Gbps.The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals as small as 100mV (200mVpp) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an internal voltage reference is provided to bias the VT pin. The outputs are 400mV CML, with extremely fast rise/fall times guaranteed to be less than 80ps.The SY56034AR operates from a 2.5V ±5% core supply and a 1.2V/1.8V/2.5V ±5% output supply and is guaranteed over the full industrial temperature range (–40°C to +85°C). The SY56034AR is part of Micrel’s high-speed, Precision Edge® product line.
