General Description
The HMC748LC3C 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 HMC748LC3C 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 HMC748LC3C
are terminated with 50 ohms to Vcc on-chip, and
may be either AC or DC coupled. The outputs of the
HMC748LC3C may be operated either differentially
or single-ended. 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 HMC748LC3C
operates from a single +3.3V DC supply and is housed
in a ceramic RoHS compliant 3x3 mm SMT package.
