ClockWorks™ SY10EL33/L SY100EL33/L 5V/3.3V ÷ 4 DIVIDER DESCRIPTION FEATURES ■ ■ ■ ■ ■ ■ The SY10/100EL33/L are integrated ÷4 dividers. The differential clock inputs and the VBB allow a differential, single-ended or AC-coupled interface to the device. If used, the VBB output should be bypassed to ground with a 0.01µF capacitor. Also note that the VBB is designed to be used as an input bias on the EL33/L only; the VBB output has limited current sink and source capability. 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 input allows for the synchronization of multiple EL33/Ls in a system. 3.3V and 5V power supply options 650ps propagation delay 4.0GHz toggle frequency High bandwidth output transistions Internal 75KΩ input pull-down resistors Available in 8-pin SOIC package PIN NAMES PIN CONFIGURATION/BLOCK DIAGRAM Pin Reset 1 8 VCC 7 Q R CLK 2 CLK 3 6 Q VBB 4 5 VEE ÷4 Function CLK Clock Inputs Reset Asynchronous Reset VBB Reference Voltage Output Q Data Outputs SOIC TOP VIEW Rev.: E 1 Amendment: /1 Issue Date: August 2000 ClockWorks™ SY10EL33/L SY100EL33/L Micrel DC ELECTRICAL CHARACTERISTICS(1) VEE (Min) to VEE (Max); VCC = GND TA = –40°C Symbol IEE VBB IIH TA = 0°C TA = +25°C TA = +85°C Parameter Min.
