HMC744 14 Gbps Fast Rise Time 1:2 Fanout Buffer with Programmable Output Voltage & Positive Supply

The HMC744LC3 is a 1:2 Fanout Buffer designed to support data transmission rates up to 14 Gbps, and clock frequencies as high as 14 GHz.

All differential inputs to the HMC744LC3 are CML and terminated on-chip with 50 Ohms to the positive supply, Vcc, and may be AC or DC coupled. The differential CML outputs are source terminated to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm Vcc-terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to ground. The HMC744LC3 also features an output level control pin, VR, which allows for loss compensation or signal-level optimization. the HMC744LC3 operates from a single 3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
