Overview
The HMC721LP3E is a high-speed XOR/XNOR gate function designed by Analog Devices Inc. to support data transmission rates of up to 14 Gbps and clock frequencies as high as 14 GHz. This component is optimized for high-speed logic applications and is available in a ROHS-compliant 3x3 mm SMT package. It operates from a single -3.3 V supply and features internally terminated differential inputs with 50 Ohms to the positive supply, allowing for both DC and AC coupling. The outputs can be connected directly to a 50 Ohm ground-terminated system or drive devices with CML logic input.
