The LMH2191 is a dual-channel clock tree driver that supplies a digital system clock to peripherals in mobile handsets or other applications. It provides a solution to clocking issues such as limited drive capability for fanout or longer traces. It also provides protection of the master clock from varying loads and frequency pulling effects, isolation from n.
