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.
