All Gigabit Ethernet applications
The SY58040U is a low jitter, low skew, high-speed
4×4 crosspoint switch optimized for precision telecom and
enterprise server/storage distribution applications. The
SY58040U distributes clock frequencies from DC to 4GHz,
and data rates to 5Gbps guaranteed over temperature and
voltage.
The SY58040U 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 outputs are 50
source-terminated CML with extremely fast rise/fall times
guaranteed to be less than 60ps.
The SY58040U features a patent-pending isolation design
that significantly improves on channel-to-channel crosstalk
performance.
The SY58040U operates from a 2.5V ±5% or 3.3V ±10%
supply and is guaranteed over the full industrial temperature
range of –40°C to +85°C. The SY58040U is part of Micrel’s
high-speed, Precision Edge product line.
