HMC678LC3C
v06.0514
13 Gbps, 2:1 SELECTOR
w/ PROGRAMMABLE OUTPUT VOLTAGE
The HMC678LC3C is a 2:1 Selector designed to sup-
port data transmission rates of up to 13 Gbps, and
selector port operation of up to 13 GHz. The selector
routes one of the two single-ended inputs to the
differential output upon assertion of the proper select
port. The HMC678LC3C also features an output level
control pin, VR, which allows for loss compensation or
for signal level optimization.
All single-ended input signals to the HMC678LC3C
are terminated with 50 Ohms to ground on-chip, and
may be either AC or DC coupled. The outputs of the
HMC678LC3C may be operated either differentially
or single-ended. Outputs can be connected directly
to a 50 Ohm terminated system, while DC blocking
capacitors may be used if the terminating system is 50
Ohms to a non-ground DC voltage. The HMC678LC3C
operates from a single -3.3V DC supply and is available
in a ceramic RoHS compliant 3x3 mm SMT package.
