Functional Diagram
General Description
The HMC958LC5 is a 4:1 Selector designed to support
data transmission rates of up to 14 Gbps and selector
port operation up to 14 GHz. The selector routes the
differential inputs to either one or both of the desired
outputs upon assertion of the appropriately selected
port.
All differential inputs to the HMC958LC5 are CML and
terminated on-chip with 50 ohms to the positive supply,
GND, and may be DC or AC coupled. Outputs can be
connected directly to a 50-ohm, ground-terminated
system or drive devices with CML logic input. the
HMC958LC5 also features an output level control pin,
VR, which allows for loss compensation or signal level
optimization. The HMC958LC5 operates from a single
-3.3 V supply and is available in a ROHS-compliant 3x3
mm SMT package.
