SY89853U
Precision Low-Power Dual 2:1 LVPECL MUX
with Internal Termination General Description
The SY89853U features two, low jitter 2:1 differential
multiplexers with 100K LVPECL (800mV) compatible
outputs, capable of handling clocks up to 2.5GHz and
data streams up to 2.5Gbps.
The SY89853U differential inputs include Micrel’s
unique, 3-input termination architecture that allows
users to interface to any differential signal (AC-or DCCoupled) as small as 100mV without any level shifting
or termination resistors networks in the signal path. The
result is a clean, stub-free, low jitter interface solution.
The differential 800mV LVPECL outputs have fast
rise/fall times guaranteed to be less than 180ps.
The SY89853U operates from a 2.5V В±5% or a 3.3V
В±10% supply, and is guaranteed over the full industrial
temperature range (–40°C to +85°C). For applications
that require higher performance, consider the
SY58026U. The SY89853U is part of Micrel's Precision
В®
Edge product family.
