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 10kΩ resistor from the unused input to VEE 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/µs. 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 330Ω and a value of 430Ω 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. 2 SP8610/11 j1 j 0.5 j2 j 0.2 1300 1400 1500 1200 1100 1000 0.2 0.5 1 2 5 j5 0 900 2j 5 2j 0.2 800 700 600 500 2j 0.5 2j 1 2j 2 Fig. 4 Typical input impedance.
