DESCRIPTION
The SY58024U is a 2.5V/3.3V precision, high-speed, fully
differential dual CML crosspoint switch. The SY58024U is
optimized to provide two identical output copies with less
than 20ps of skew and ultra-low jitter. The SY58024U can
process clock signals as fast as 6GHz or data patterns up
to 10.7Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows the SY58024U to directly
interface to LVPECL, LVDS, and CML differential signal
(AC- or DC-coupled) without any level-shifting or termination
resistor networks in the signal path. The CML outputs
features a 400mV typical swing into 50Ω loads, and provides
an extremely fast rise/fall time guaranteed to be less than
60ps.
The SY58024U 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 single channel CML switches, consider
the SY58023U. The SY58024U is part of Micrel’s high-
speed, Precision Edge™ product line.
