General Description
The SY89847U is a 2.5V, 1:5 LVDS fanout buffer
with a 2:1 differential input multiplexer (MUX). A
unique Fail-Safe Input (FSI) protection prevents
metastable output conditions when the selected
input clock fails to a DC voltage (voltage between
the pins of the differential input drops significantly
below 100mV).
The differential input includes Micrel’s unique, 3-pin
internal termination architecture that can 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
outputs are LVDS compatible with very fast rise/fall
times guaranteed to be less than 210ps.
The SY89847U operates from a 2.5V ±5% supply
and
is
guaranteed
over
the
full
industrial
temperature
range
of
–40°C to +85°C. The
SY89847U is part of Micrel’s high-speed, Precision
Edge
product line.
