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.
