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.
