3 - 1
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.
