C™ interface. The LMH2190 provides a digital system clock to peripheral devices
in mobile handsets. It provides a solution to clocking issues such as limited drive capability for fanout or
longer traces, protection of the master clock from varying loads and frequency pulling effects, isolation
buffering from noisy modules, and crosstalk isolation. It has very low phase noise which enables it to drive
sensitive modules such as Wireless LAN and Bluetooth.
