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.

Note 1.
Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions
for extended periods may affect device reliability.
Due to the limited drive capability, the VBB reference should only be used for inputs from the same packge device (i.e., do not sue for other
devices).
