Functional Diagram
General Description
The HMC724LC3C is a 1:2 Fanout Buffer designed to
support data transmission rates up to 14 Gbps, and
clock frequencies as high as 14 GHz. All differential
inputs and outputs are DC coupled and terminated on
chip with 50 Ohm resistors to ground. The outputs may
be used in either single ended or differential modes,
and should be AC or DC coupled into 50 Ohm resistors
connected to ground.
All differential inputs to the HMC724LC3C are CML
and terminated on-chip with 50 Ohms to the positive
supply, GND, and may be DC or AC coupled. The
differential CMl outputs are source terminated to to 50
Ohms and may also be AC or DC coupled. Outputs can
be connected directly to a 50 Ohm ground-terminated
system or drive devices with CML logic input. The
HMC724LC3C operates from a single -3.3 V supply and
is available in ROHS-compliant 3x3 mm SMT package.

List of Materials for Evaluation PCB 122520 [1]
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package gro-
und 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.
