DESCRIPTION
The SY58601U is a 2.5V/3.3V precision, high-speed,
differential receiver capable of handling clocks up to 5GHz
and data streams up to 5Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows users to interface to any
differential signal (AC or DC-coupled) as small as 200mV_pp
without any level shifting or termination resistor networks in
the signal path. The outputs are 800mV LVPECL, with
extremely fast rise/fall times guaranteed to be less than
90ps.
The SY58601U 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 CML outputs, consider the SY58600U or for
400mV LVPECL outputs the SY58602U. The SY58601U is
part of Micrel’s high-speed, Precision Edge^® product line.
