General Description
Functional Diagram
The HMC744LC3C is a 1:2 Fanout Buffer designed to
support data transmission rates up to 13 Gbps, and
clock frequencies as high as 13 GHz. The HMC744LC3C also features an output level control pin, VR,
which allows for loss compensation or for signal level
optimization.
All input and output signals to the HMC744LC3C are
terminated with 50 Ohms to Vcc on-chip, and may
be either AC or DC coupled. Inputs or outputs can
be connected directly to a 50 Ohm to Vcc terminated
system, while DC blocking capacitors may be used
if the terminating system is 50 Ohms to ground. The
HMC744LC3C operates from a single +3.3V DC supply,
and is available in a ceramic RoHS compliant 3x3 mm
SMT package.

122515 Evaluation Board
[1] Reference this number when ordering complete evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground leads should be connected directly to the
ground plane similar to that shown. The exposed
packaged base should be connected to GND. A
sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Hittite upon request.
