General Description
The HMC850LC3 is a 1:2 Fanout Buffer designed to
support data transmission rates up to 28 Gbps, and
clock frequencies as high as 20 GHz. All differential
inputs and outputs are DC coupled and terminated
on chip with 50 Ohm resistors to the positive supply,
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 HMC850LC3 also features an output level control
pin, VR which allows for loss compensation or for signal
level optimization. The HMC850LC3 operates from a
single -3.3V DC supply and is available in a ceramic
RoHS compliant 3x3 mm SMT package.
