Features & Applications

The SY54017ARMG is a fully differential, low voltage 1.2 V/1.8 V CML 2:1 MUX. The SY54017AR can process clock signals as fast as 3.2 GHz or data patterns up to 3.2 Gbps.

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 2.5 V driver) as small as 100 mV (200 mV PP) 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 V T pin. The outputs are CML, with extremely fast rise/fall times guaranteed to be less than 95ps. The SY54017AR operates from a 2.5 V ±5% core supply and a 1.8 V or 1.2 V ±5% output supply and is guaranteed over the full industrial temperature range  (–40°C to +85°C). The SY54017AR is part of Micrel’s high-speed, Precision Edge ® product line.
