General Description
The SY89645L is a 3.3V, fully differential, low skew, 1:4
LVDS fanout buffer that accepts LVTTL or LVCMOS
inputs. It is capable of processing clock signals as fast as
650MHz. The LVDS signals are optimized to provide less
than 40ps of output skew.
The single-ended input takes a 3.3V LVTTL or LVCMOS,
with a signal swing as small as 1.2V. The outputs are
280mV LVDS, with fast rise and fall times, guaranteed to
be less than 400ps.
The SY89645L operates from a 3.3V + 5% power supply
and is guaranteed over the full industrial temperature
range (–40°C to +85°C). The SY89645L is part of Micrel’s
Precision Edge
product line.
