DESCRIPTION
The SY10/100EP32V is an integrated
÷2
divider with
differential clock inputs.
The V
BB
pin, an internally generated voltage supply,
is available to this device only. For single-ended input
conditions, the unused differential input is connected to
V
BB
as a switching reference voltage. V
BB
may also rebias
AC-coupled inputs. When used, decouple V
BB
and V
CC
via a 0.01µF capacitor and limit current sourcing or sinking
to 0.5mA. When not used, V
BB
should be left open.
The reset pin is asynchronous and is asserted on the
rising edge. Upon power-up, the internal flip-flops will
attain a random state; the reset allows for the
synchronous use of multiple EP32’s in a system.
The 100k series includes internal temperature
compensation circuitry.
