General Description
The SY58609U is a 2.5/3.3V, high-speed, fully
differential CML 2:1 MUX capable of processing clock
signals up to 2.5GHz and data patterns up to
4.25Gbps. The SY58609U is optimized to provide a
buffered output of the selected input with less than
20ps of skew and less than 10pspp total jitter.
The differential input includes Microchip’s unique, 3-pin
input termination architecture that interfaces to
LVPECL, LVDS or CML differential signals, (AC- or
DC-coupled) as small as 100mV (200mVpp) without
any level-shifting or termination resistor networks in the
signal path. For AC-coupled input interface
applications, an integrated reference voltage (V
REF-AC
)
is provided to bias the VT pin. The outputs are 400mV
CML, with extremely fast rise/fall times guaranteed to
be less than 90ps.
The SY58609U 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 LVPECL or LVDS outputs,
consider Microchip’s SY58610U and SY58611U, 2:1
MUX with 800mV and 325mV output swings,
respectively. The SY58609U is part of Microchip’s
high-speed Precision Edge
®
product line.
