ADVANCE INFORMATION
DS3664-1*2
SP8630
600MHz410 4
The SP8630 is an asynchronous emitter coupled logic divider which provides an ECLlll/10K compatible output when used with an external pulldown resistor. It requires an AC coupled input of 600mV p-p.

OPERATING NOTES
1. The clock input (pin 10) should be capacitively coupled to the signal source. The input signal path is completed by connecting a capacitor from the internal bias decoupling, pin 12, to ground. 2. The circuit will operate down to DC but slew rate must be better than 100V/s. 3. The output is compatible with ECLll. There is an internal load of 3k at the output. The output can be interfaced to ECLlll/10K by the addition of 1*5k to the output to increase the output voltage swing. 4. Input impedance is a function of frequency, see Fig. 4. 5. All components should be suitable for the frequency in use.
