LMH2190 Datasheet Quad Channel 26 Mhz Clock Tree Driver

Manufacturer: National Semiconductor Corporation

Overview: LMH2190 Quad Channel 26 MHz Clock Tree Driver with I2C Interface www.DataSheet4U.

General Description

The LMH2190 is a quad channel configurable clock distribution device which supplies the system clock to peripherals in mobile handsets or other applications.

It provides a solution to clocking issues such as 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.

Key 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 I2C serial interface can be used to override the default configuration of the device to optimize the LMH2190 for the.
