LMH2191 Dual Channel 52 MHz Clock Tree Driver

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.

One Input Clock, Two Output Clocks  
1.8V Square Wave Clock Outputs  
Inverted Clock Outputs  
Independent Clock Requests  
High Isolation of Supply Noise to Clock Input  
High Output-to-Output Isolation  
Integrated 1.8V Low-Dropout Regulator  
Low Output-Noise Voltage  
10 mA Load Current  
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.
