DESCRIPTION
The SY58018U is a 2.5V/3.3V precision, high-speed, 2:1
differential MUX capable of handling clocks up to 4GHz
and data up to 5Gbps.
The differential input includes Micrel鈥檚 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 800mV, 100k
compatible, LVPECL, with extremely fast rise/fall times
guaranteed to be less than 110ps.
The SY58018U operates from a 2.5V
鹵5%
supply or a
3.3V
鹵10%
supply and is guaranteed over the full industrial
temperature range of 鈥?0擄C to +85擄C. For applications that
require CML outputs, consider the SY58017U or for 400mV
LVPECL outputs the SY58019U. The SY58018U is part of
Micrel鈥檚 high-speed, Precision Edge鈩?product line.
All support documentation can be found on Micrel鈥檚 web
