General Description
The HMC670LC3C is a 1:2 Fanout Buffer designed to
support data transmission rates up to 13 Gbps, and
clock frequencies as high as 13 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.
The HMC670LC3C also features an output level control
pin, VR which allows for loss compensation or for signal
level optimization. The HMC670LC3C operates from a
single -3.3V DC supply and is available in a ceramic
RoHS compliant 3x3 mm SMT package.
