SY54017R Product Brief Low Voltage 1.2V/1.8V CML 2:1 Multiplexer with Fail Safe Input (3.2Gbps, 2.5GHz) Description The SY54017R is a fully differential, low voltage 1.2V/1.8V CML 2:1 MUX with Fail Safe Inputs. The Fail Safe Inputs include a dedicated circuit to sense the amplitude of the input signal and to latch the output when there is no input signal present, or when the amplitude of the input signal drops sufficiently below 100mVPK (200mVPP). The SY54017R can process clock signals as fast as 2.5GHz 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 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 CML, with extremely fast rise/fall times guaranteed to be less than 95ps. The SY54017R 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 SY54017R is part of Micrel’s high-speed, Precision Edge® product line.
