FEATURES
Guaranteed maximum frequency > 4GHz 3.3V and 5V power supply options Guaranteed propagation delay <440ps over temperature Internal 75K input pull-down resistors Wide operating temperature range: -40C to +85C Available in 8-pin MSOP and SOIC packages
ECL ProTM 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 0.01F 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.

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).
