General Description
The HMC791LC4B is a low-noise divide-by-2, divide-
by-4 designed to support input clock frequencies
as high as 28 GHz. When an input clock signal is
applied, divide-by-2 and divide-by-4 outputs are
observed simultaneously. All input signals to the
HMC791LC4B are terminated with 50Ω to ground
on-chip, and may be either AC or DC coupled. Out-
puts can be connected directly to a 50Ω terminated
system, while DC blocking capacitors must be used if
the terminating system is 50Ω to a non-zero voltage.
The HMC791LC4B operates from a single -3.3V DC
supply and is available in a ceramic RoHS compliant
SMT package.
