Precision Low Power Differential 2:1
LVPECL MUX with Internal Termination General Description
The SY89852U is a 2.5V/3.3V precision, highspeed, 2:1 differential MUX capable of handling
clocks up to 2.5GHz and data streams up to
2.5Gbps.
The differential input includes Micrel’s unique, patent
pending 3-pin input termination architecture that
allows users to interface to any differential signal
(AC-or DC-coupled) as small as 100mV (200mVpp)
without any level shifting or termination resistor
networks in the signal path. The unique, patent input
isolation design minimizes crosstalk minimizing
crosstalk induced jitter. The outputs are 800mV
LVPECL, with extremely fast rise/fall time
guaranteed to be less than 180ps.
The SY89852U operates from a 2.5V В±5% supply or
a 3.3V В±10% supply and is guaranteed over the full
industrial temperature range of –40°C to +85°C.
The SY89852U is part of Micrel’s high-speed,
