The HMC745LC3C is a XOR/XNOR gate function

designed to support data transmission rates of up to 13

Gbps, and clock frequencies as high as 13 GHz. The

HMC745LC3C also features an output level control pin,

VR, which allows for loss compensation or for signal

level optimization.

All input and output signals to the HMC745LC3C are

terminated with 50 Ohms to Vcc on-chip, and may

be either AC or DC coupled. Inputs or outputs can

be connected directly to a 50 Ohm to Vcc terminated

system, while DC blocking capacitors may be used

if the terminating system is 50 Ohms to ground. The

HMC745LC3C operates from a single +3.3V DC supply,

and is available in a ceramic RoHS compliant 3x3 mm

SMT package.
