The SY58019U 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 400mV, 100k

compatible, LVPECL, with extremely fast rise/fall times

guaranteed to be less than 70ps.

The SY58019U 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 SY58017U or for 800mV

LVPECL outputs the SY58018U. The SY58019U is part of

All support documentation can be found on Micrel’s web
