Description
The ZL40813, 14 and 18 are 5V supply, very high
speed low power prescalers for professional
applications with a fixed modulus of 8, 16, or 4
respectively. The dividing elements are dynamic D type
flip flops and allow operation from 10.5GHz to 13.5GHz
with a sinewave input (Note these prescalers are not
suitable for D.C. operation). The output stage has
internal 50 ohm pull up giving a 1v p-p output. See
application notes for more details.

Electrical Characteristics (Vcc = 5V ±5%, Tamb = -40 to +85C)
The following characteristics are guaranteed by design and characterisation over the range of operating conditions
unless otherwise stated:

† Pin 1 is the Vcc pin for the 1st stage bias current. In some applications e.g. if the power supply is noisy, it may be advantageous to add further
supply decoupling to this pin (i.e. an additional R, C filter, see diagram of the recommended circuit configuration, Figure 9).

4.0 Oscillographs of the divider output waveforms
The following oscillographs show that the low-level feedthrough of the input waveform can be further reduced by
summing the two output pins of the device differentially, refer to Figure 16 and Figure 17.
Figure 16 - Single-ended output waveform, showing some feedthrough of the input waveform.
