Functional Diagram
General Description
The HMC848LC5 is a 1:4 demultiplexer designed for
data deserialization up to 45 Gbps. The device uses
both rising and falling edges of the half-rate clock to
sample the input data in sequence, D0-D3 and latches
the data onto the differential outputs. A quarter-rate
clock output generated on-chip can be used to clock
the data into other devices.
All clock and data inputs / outputs of the HMC848LC5
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 HMC848LC5 may be operated either
differentially or single-ended. The HMC848LC5 also
features an output level control pin, VCTRL, which allows
for loss compensation or signal level optimization. The
HMC848LC5 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.
