General Description
The HMC725LC3C is a XOR/XNOR gate function
designed to support data transmission rates of up to 14
Gbps, and clock frequencies as high as 14 GHz.
All differential inputs to the HMC725LC3C are CML
and terminated on-chip with 50 Ohms to the positive
supply, GND, and may be DC or AC coupled. The
differential CMl outputs are source terminated to to 50
Ohms and may also be AC or DC coupled. Outputs can
be connected directly to a 50 Ohm ground-terminated
system or drive devices with CML logic input. The
HMC725LC3C operates from a single -3.3 V supply and
is available in ROHS-compliant 3x3 mm SMT package.
