General Description
The SY58608U is a 2.5V, high-speed, fully differential
1:2 LVDS fanout buffer optimized to provide two
identical output copies with less than 20ps of skew and
130fs
RMS
typical additive phase jitter. The SY58608U
can process clock signals as fast as 2GHz or data
patterns up to 3.2Gbps.
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 (200mV
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 325mV
LVDS, with rise/fall times guaranteed to be less than
100ps.
The SY58608U operates from a 2.5V ±5% supply and
is guaranteed over the full industrial temperature range
(–40°C to +85°C). The SY58608U is part of Microchip’s
high-speed, Precision Edge
®
product line.
