General Description
The SY58607U is a 2.5V/3.3V, high-speed, fully
differential 1:2 LVPECL fanout buffer optimized to
provide two identical output copies with less than 20 ps
of skew. The SY58607U can process clock signals as
fast as 2.5 GHz or data patterns up to 3.2 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 mVPP) without
any level-shifting or termination resistor networks in the
signal path. For AC-coupled input interface
applications, an integrated voltage reference
(VREF-AC) is provided to bias the VT pin. The outputs
are 800 mV LVPECL, with extremely fast rise/fall times
guaranteed to be less than 110 ps.
The SY58607U 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 CML or LVDS outputs,
consider Microchip’s SY58606U and SY58608U, 1:2
fanout buffers with 400 mV and 325 mV output swings
respectively. The SY58607U is part of Microchip’s
high-speed, Precision Edge® product line.
