GENERAL DESCRIPTION
The ADF5000 prescaler is a low noise, low power, fixed RF
divider block that can be used to divide down frequencies as
high as 18 GHz to a lower frequency suitable for input to a
PLL IC, such as the ADF4156 or the ADF4106. The ADF5000
provides a divide-by-2 function. The ADF5000 operates from
a 3.3 V supply and has differential 100 Ω RF outputs to allow
direct interface to the differential RF inputs of PLLs such as
the ADF4156 and ADF4106.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Data Sheet
