General Description
Functional Diagram
The HMC720LP3E 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 to the HMC720LP3E are CML and
terminated on-chip with 50 Ohms to the positive supply,
GND, and may be DC or AC coupled. Outputs can be
connected directly to a 50 Ohm ground-terminated
system or drive devices with CML logic input. The
HMC720LP3E also features an ouput level control pin,
VR, which allows for loss compensation or signal level
optimization. The HMC720LP3E operates from a single
-3.3 V supply and is available in ROHS-compliant 3x3
mm SMT package.

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 Vee. 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. Install jumper on JP1 to short
VR to GND for normal operation.
