The SP8610 and SP8611 are asynchronous ECL divide by
four circuits with ECL compatible outputs which can also be
used to drive 100
lines. They feature input sensitivities of
600mV p-p (800mV p-p above 1300MHz).

OPERATING NOTES
1. The clock input (pin 4) should be capacitively coupled to the
signal source. The input signal path is completed by connecting
a capacitor from the internal bias decoupling, pin 6, to ground.
2. In the absence of a signal the device will self-oscillate. If this is
undesirable, it may be prevented by connecting a 10k
resistor
from the unused input to V
EE
i.e. from pin 4 to pin 7. This will reduce
the input sensitivity by approximately 100mV.
3. The circuit will operate at very low input frequencies but slew
rate must be better than 200V/
s.
4. The input impedance of the SP8610/11 is a function of frequency,
see Fig. 4.
5. The emitter follower outputs require external load resistors.
These should not be less than 330
and a value of 430
is
recommended. Interfacing to ECLlll/10K is shown in Fig. 7.
6. These devices may be used with split suopply lines and ground
referenced input; a suitable configuration is shown in Fig. 6.
7. All components should be suitable for the frequency in use.
