Package
General Description
The SY58606U is a 2.5/3.3V, high-speed, fully
differential 1:2 CML fanout buffer optimized to provide
two identical output copies with less than 15 ps of skew
and 100 fs
RMS
of typical additive phase jitter. The
SY58606U can process clock signals as fast as 3 GHz
or data patterns up to 4.25 Gbps.
The differential input includes Microchip’s unique,
3-lead input termination architecture that interfaces to
LVPECL, LVDS, or CML differential signals, (AC- or
DC-coupled) as small as 100 mV (200 mV
PP
) without
any level-shifting or termination resistor networks in the
signal path. For AC-coupled input interface
applications, an integrated voltage reference (V
REF-AC
)
is provided to bias the V
T
pin. The outputs are 400 mV
CML, with extremely fast rise/fall times guaranteed to
be less than 85 ps.
The SY58606U 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 SY58607U and SY58608U, 1:2
fanout buffers with 800 mV and 325 mV output swings
respectively. The SY58606U is part of Microchip’s
high-speed, Precision Edge
®
product line.
