Functional Diagram
General Description
The HMC842LC4B is a 1:2 Fanout Buffer designed
to support data transmission rates up to 45 Gbps.
The device can also operate with clock signals up to
28 GHz. During normal operation, input data (or clock)
is transferred to both output channels. Differential input
and output signals of the HMC842LC4B are terminated
with 50 Ohms to ground on-chip, and may be either AC
or DC coupled. The Outputs can be connected directly
to a 50 Ohms-to-ground terminated system, while DC
blocking capacitors should be used if the terminating
system is 50 Ohms to a non-ground DC voltage.
The HMC842LC4B also features two separate output
level control pins, VAC1 and VAC2 which provide loss
compensation and signal level optimization for each
output channel independently. The HMC842LC4B
operates from a single -3.3V DC supply and is available
in a ceramic RoHS compliant 4 x 4 mm SMT package.
