Functional Diagram
General Description
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.
