Functional Diagram
General Description
The HMC847LC5 is a 4:1 multiplexer designed for
45Gbps data serialization. The mux latches the four
differential inputs on the transition points 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, which is synchronous to the data output of
HMC847LC5, is generated on chip.
All clock and data inputs / outputs of the HMC847LC5
are CML and terminated on-chip with 50 Ohms to
the, VCC, and may be DC or AC coupled. The inputs
and outputs of the HMC847LC5 may be operated
either differentially or single-ended. The HMC847LC5
also features an output level control pin, VCTRL,
which allows for loss compensation or signal level
optimization. The VDCC pin controls the data output
cross-point & duty cycle. The HMC847LC5 operates
from a single +3.3V supply and is available in ROHS
compliant 5x5 mm SMT package.

126672 Evaluation Board
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground leads should be connected directly to the
ground plane similar to that shown. The exposed
metal package base must be connected to GND.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Hittite upon request.
