HMC720LP3E

HMC720LP3E is a 1:2 fan-out buffer designed to support data transmission rates up to 14Gbps, and clock frequencies as high as 14GHz. All differential inputs to the HMC720LP3E are CML and terminated on-chip with 50 ohm 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 HMC720LP3E also features an output level control pin, VR which allows for loss compensation or signal level optimization. Typical applications include 16G fibre channel, RF ATE applications, broadband Test & Measurement, serial data transmission up to 14Gbps and clock buffering up to 14GHz.
