General Description
The SY55859L is a dual CML 2x2 crosspoint switch
optimized for high-speed data and/or clock applications
(up to 3.2Gbps or 2.7GHz) where low jitter and skew are
critical. This device is pin-for-pin, plug-in compatible to the
MAX3840. Each 2x2 of the SY55859L routes any input to
any output, and thus can distribute or multiplex a clock or
data stream. The I/O architecture is fully differential and
CML compatible. Both inputs and outputs are optimized for
50 transmission lines. The inputs (DA 0-1 and DB 0-1)
are internally terminated with 50, thus eliminating
external termination, and the outputs (QA0-1 and QB0-1)
include 50 source termination. Furthermore, a power-
saving output enable feature is provided which powers-
down unused outputs.
The SY5859L operates from a +3.3V ±10% supply, and is
guaranteed
over
the
industrial
(–40°C
to
+85°C)
temperature range.
It is available in a 32-pin (5mm x
5mm) QFN package.
For applications that require either lower voltage operation
or a more flexible input interface (for applications such as
AC–coupled LVPECL inputs), consider the SY55858U.
