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.
