Functional Diagram
General Description
The HMC847LC5 is a 4:1 multiplexer for operation at
output data rate up to 36 Gbps. The mux latches the
four differential inputs on falling edge of the input clock
CKIN (See timing diagram on page.6). 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.
