General Description
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 HMC744-
LC3C 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.
