LMH2190 Datasheet Clock Tree Driver

Manufacturer: Texas Instruments

Overview: LMH2190 www.ti.com SNAS473H – JUNE 2009 – REVISED MAY 2013 LMH2190 Quad Channel 27 MHz Clock Tree Driver with I2C Interface Check for Samples:.

General Description

The LMH2190 is a quad channel configurable clock tree driver which 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, 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.
