Functional Diagram
General Description
The HMC844LC4B is an XOR/XNOR function designed to support data transmission rates of up to
45 Gbps, and clock frequencies as high as 25 GHz.
The HMC844LC4B may be easily configured to
provide either XOR or XNOR logic functions. The
HMC844LC4B also features an output level control pin,
VAC, which allows for loss compensation or for signal
level optimization.
All input signals to the HMC844LC4B are terminated
with 50 Ohms-to-ground on-chip, and may be either
AC or DC coupled. The differential outputs of the
HMC844LC4B may be either AC or DC coupled.
Outputs can be connected directly to a 50 Ohms-toground terminated system, while DC blocking capacitors should be used if the terminating system is 50
Ohms to a non-ground DC voltage. The HMC844LC4B
operates from a single -3.3V DC supply, and is available
in a ceramic RoHS compliant 4x4 mm SMT package.

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 Vee. 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.
