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 4x4 mm SMT package.
