General Description
The SY89540U is a low-jitter, low skew, high-speed
4x4 crosspoint switch optimized for precision telecom
and enterprise server/storage distribution applications.
The SY89540U guarantees data-rates up to 3.2Gbps
over temperature and voltage.
The SY89540U differential input includes Micrel’s
unique,
3-pin
input
termination
architecture
that
directly interfaces 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 LVDS compatible outputs maintain
extremely fast rise/fall times guaranteed to be less
than 120ps.
The SY89540U features a patent-pending isolation
design that significantly improves on channel-to-
channel crosstalk performance.
The SY89540U operates from a 2.5V ±5% supply and
is guaranteed over the full industrial temperature range
(
–40°C to +85°C). The SY89540U is part of Micrel’s
high-speed, Precision Edge
product line.
All support documentation can be found on Micrel’s
