Precision Edge™ 5V/3.3V 4GHz, SY10EP33V SY100EP33V ? 4 PECL/LVPECL DIVIDER FINAL FEATURES Guaranteed maximum frequency >4GHz 3.3V and 5V power supply options ECL Pro™ Guaranteed propagation delay <460ps over temperature DESCRIPTION Wide operating temperature range: –40°C to +85°C The SY10/100EP33V is an integrated ?4 divider. Available in 8-pin MSOP and SOIC packages 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 i
