Status: In Production
The SY54023AR is a fully differential, low voltage 1.2V/1.8V CML 2x2 Crosspoint Switch. The SY54023AR can process clock signals as fast as 3.2 GHz or data patterns up to 3.2Gbps.The differential input includes Micrel's unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC- or DC-coupled from a 2.5V driver) 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 400 mV CML, with extremely fast rise/fall times guaranteed to be less than 95ps.The SY54023AR operates from a 2.5V ±5% core supply and a 1.8V or 1.2V ±5% output supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY54023AR is part of Micrel's high-speed, Precision Edge® product line.
