General Description
The SY10/100EP33V is an integrated ÷4 divider.
The VBB pin, an internally-generated voltage supply, is
available to this device only. For single-ended input
conditions, the unused differential input is connected to
VBB as a switching reference voltage. VBB may also rebias
AC-coupled inputs. When used, decouple VBB to VCC via a
0.01µF capacitor and limit current sourcing or sinking to
0.5mA. When not used, VBB 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 EP33s in a system.
The 100K Series includes internal temperature
compensation circuitry.
