The SY58023U is a 2.5V/3.3V precision, high-speed, fully
differential CML 2×2 crosspoint switch. The SY58023U is
optimized to provide two identical output copies with less
than 20ps of skew and ultra-low jitter. It can route clock
signals as fast as 6GHz or data up to 10.7Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows the SY58023U to directly
interface to LVPECL, LVDS, and CML differential signals
(AC- or DC-coupled) as small as 100mV (200mV
pp
) without
any level-shifting or termination resistor networks in the signal
path. The CML outputs features 400mV typical swing into
50Ωloads, and provide an extremely fast rise/fall time
guaranteed to be less than 60ps.
The SY58023U operates from a +2.5V ±5% supply or
+3.3V ±10% supply and is guaranteed over the full industrial
temperature range (–40°C to +85°C). For applications that
require high speed dual CML switches, consider the
SY58024U. The SY58023U is part of Micrel’s high-speed,
