Check for Samples: LMH2191 FEATURES DESCRIPTION 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 noisy
modules, and crosstalk isolation. It has very low
phase noise which enables it to drive sensitive
modules such as Wireless LAN and Bluetooth. 1 2 One Input Clock, Two Output Clocks
