General Description
The HMC721LC3C 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 HMC721LC3C are CML and
terminated on-chip with 50 Ohms to the positive supply,
GND, and may be DC or AC coupled. Outputs can be
connected directly to a 50 Ohm ground-terminated
system or drive devices with CML logic input. The
HMC721LC3C also features an ouput level control pin,
VR, which allows for loss compensation or signal level
optimization. The HMC721LC3C operates from a single
-3.3 V supply and is available in ROHS-compliant 3x3
mm SMT package.
