MICROCHIP SY58034UMI-TR

The SY58034U is a 2.5V/3.3V precision, high-speed 1:6 fanout buffer capable of handling clocks up to 6GHz. A differential 2:1 MUX input is included for redundant clock switchover applications. The differential input includes Micrel’s unique, 3-pin input termination architecture that allows the device to interface to any differential signal (AC- or DC-coupled) as small as 100mV without any level shifting or termination resistor networks in the signal path. The outputs are 50ý source terminated CML, with extremely fast rise/fall times guaranteed to be less than 60ps. The SY58034U operates from a 2.5V±5% supply or a 3.3V±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. For applications that require LVPECL outputs, consider the SY58035U or SY58036U Multiplexers.
