Manufacturer: Texas Instruments

Overview: LMH2191 www.ti.com SNAS485D – JULY 2010 – REVISED MAY 2013 LMH2191 Dual Channel 52 MHz Clock Tree Driver Check for Samples:.

General 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.
