Power supply 2.5V В±5% or 3.3V В±10%
–40°C to +85°C temperature range
Available in 16-pin (3mm x 3mm) QFN package Precision EdgeВ® 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’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 800mV, 100k …
