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.
The LMH2191 can be clocked up to 52 MHz and has an independent clock request pin for each clock output which allows the peripheral to control the clock. It features an integrated LDO which provides an ultra low-noise voltage supply with 10 mA external load current which can be used to supply the TCXO or other clock source. The LMH2191 dual clock distributor is offered in a tiny 1.61 mm x 1.063 mm 8-bump DSBGA package. Its small size and low supply current make it ideal for portable applications.
