ClockWorks™ SY10EL32V SY100EL32V 5V/3.3V ÷ 2 DIVIDER FEATURES ■ ■ ■ ■ ■ ■ DESCRIPTION The SY10/100EL32V are integrated ÷2 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 EL32V 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-on, the internal flip-flop will attain a random state; the reset allows for the synchronization of multiple EL32Vs in a system. 3.3V and 5V power supply options 510ps propagation delay 3.0GHz 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 CLK 2 8 VCC 7 Q R ÷2 CLK 3 6 Q VBB 4 5 VEE Function CLK Clock Inputs Reset Asynchronous Reset VBB Reference Voltage Output Q Data Outputs SOIC TOP VIEW Rev.: C 1 Amendment: /0 Issue Date: August, 1998 ClockWorks™ SY10EL32V SY100EL32V Micrel DC ELECTRICAL CHARACTERISTICS(1) VEE = VEE (Min.) to VEE (Max.); VCC = GND TA = –40°C Symbol Parameter Power Supply Current IEE VBB IIH TA = 0°C TA = +25°C TA = +85°C Min.

Parametric values specified at: 10/100EL32V Series: -3.0V to -5.5V. 2. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ≈40. 3. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPP min. and 1V. The lower end of the CMR range varies 1:1 with VEE. The numbers in the spec table assume a nominal VEE = –3.3V. Note for PECL operation, the VCMR (min) will be fixed at 3.3V – |VCMR (min)|.
