DESCRIPTION
The SY58017U is a 2.5V/3.3V precision, high-speed, 2:1
differential MUX capable of handling clocks up to 7GHz
and data up to 10.7Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows customers 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 50Ω source
terminated CML, with extremely fast rise/fall times
guaranteed to be less than 60ps.
The SY58017U 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 SY58018U or
SY58019U Multiplexers with LVPECL outputs. The
SY58017U is part of Micrel’s high-speed, Precision Edge^®
product line.
