Functional Diagram
General Description
The HMC854LC5 is a 4:1 multiplexer designed for
28Gbps data serialization. The mux latches the four
differential inputs on a rising edge of the input clock.
The device uses both rising and falling edges of the
half-rate clock to serialize the data. A quarter-rate clock
output generated on chip can be used to synchronize
data into the mux. The mux is DC coupled supporting
broadband operation.
All clock and data inputs to the HMC854LC5 are CML
and terminated on-chip with 50 Ohms to the positive
supply, GND, and may be DC or AC coupled. The
differential outputs are source terminated to 50 Ohms
and may also be AC or DC coupled. Outputs can be
connected directly to a 50 Ohm ground terminated
system, or drive devices with CML logic input. The
HMC854LC5 also features an output level control pin,
VR, which allows for loss compensation or signal level
optimization. The HMC854LC5 operates from a single
-3.3V supply and is available in ROHS compliant 5x5
mm SMT package.
