LMH2180 is a high-speed dual clock buffer for portable communications and applications that require multiple precise multi-clock system designs. LMH2180 integrates two 75 MHz low-noise buffers in a small package with independent shutdown pins. The baseband between LMH2180 and the oscillating signal path that eliminates crosstalk between multiple clock signals ensure best-in-class system operation.

The unique technology and design provide the LMH2180 to accurately drive two large capacitive and resistive loads. The combination of low supply current, shutdown pins for each channel LMH2180 ideal for battery-powered applications. This section does not use an internal ground reference, providing additional system flexibility.

Flexible buffers provide system designers with the ability to manage complex clock signals in the latest wireless applications. Each buffer provides an internal slew rate of 106 V/μs with independent shutdown and duty cycle accuracy. Each input is internally biased to 1V, removing the need for external resistors that are no longer needed. These two channels have a rail-to-rail input and output with a gain of 1 and are AC coupled with the use of a capacitor.

LMH2180 discrete buffer replacement provides many benefits: simplified board layout, minimal parasitic components, simplified BOM, design durability between multiple applications, simplified clock paths, and the ability to reduce the system's clock signal generator. LMH2180 is small-scale package production that minimizes the printed circuit board (PCB) space required.
