Functional Diagram
General Description
The HMC858LC4B is a 2:1 Selector designed to
sup-port data transmission rates of up to 14 Gbps,
and selector port operation of up to 14 GHz. The
selector routes one of the two differential inputs to the
differential output upon assertion of the proper select
port. The HMC858LC4B also features an output level
control pin, VR, which allows for loss compensation or
for signal level optimization.
All differential input signals to the HMC858LC4B
are terminated with 50 ohms to ground on-chip, and
may be either AC or DC coupled. The outputs of the
HMC858LC4B 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 HMC-
858LC4B operates from a single -3.3V DC supply and
is available in a ceramic RoHS-compliant, 4x4 mm
SMT package.
