OPERATING NOTES
1. The clock inputs (pins 1 and 2) can be driven single ended or differentially and should be capacitively coupled to the signal source. The input signal path is completed by connecting a capacitor from the internal bias decoupling, pin 3, 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 15k resistor from the unused input to VEE. This will reduce the input sensitivity by approximately 100mV. 3. The circuit will operate down to DC but slew rate must be better than 100V/s. 4. The outputs are compatible with ECLII. There is an internal load of 4k on each output. The outputs can be interfaced to ECL10K by the addition of 1*5k pulldown resistors from the outputs to VEE to increase output voltage swing. 5. Input impedance is a function of frequency, See Fig. 4. 6. All components should be suitable for the frequency in use.
