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 15kΩ resistor

from the unused input to V

. 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/µs.

4. The outputs are compatible with ECLII. There is an internal load

of 4kΩ on each output. The outputs can be interfaced to ECL10K

by the addition of 1·5kΩ pulldown resistors from the outputs to V

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.
