DESCRIPTION

The SY10/100EP32V is an integrated ÷2 divider with

differential clock inputs.

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 and 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 EP32’s in a system.

The 100k series includes internal temperature

compensation circuitry.
