LMH2180 75 MHz Dual Clock Buffer  
Check for Samples: LMH2180

FEATURES  
DESCRIPTION  
The LMH2180 is a high speed dual clock buffer  
designed for portable communications and  
2

(Typical Values are: VSUPPLY = 2.7V and CL = 10  
pF, unless Otherwise Specified.)  
applications requiring multiple accurate multi-clock  
systems. The LMH2180 integrates two 75 MHz low  
noise buffers with independent shutdown pins into a  
small package. The LMH2180 ensures superb  
system operation between the baseband and the  
oscillator signal path by eliminating crosstalk between  
the multiple clock signals.

Small Signal Bandwidth 78 MHz  
Supply Voltage Range 2.4V to 5V  
Phase Noise (VIN = 1 VPP, fC = 38.4 MHz, Δf = 1  
kHz) −123 dBc/Hz

Crosstalk Rejection Circuitry  
Packages:  
Unique technology and design provides the LMH2180  
with the ability to accurately drive both large  
capacitive and resistive loads. Low supply current  
combined with shutdown pins for each channel  
means the LMH2180 is ideal for battery powered  
applications. This part does not use an internal  
ground reference, thus providing additional system  
flexibility.  
The flexible buffers provide system designers the  
capacity to manage complex clock signals in the  
latest wireless applications. Each buffer delivers 106  
V/μs internal slew rate with independent shutdown  
and duty cycle precision. Each input is internally  
biased to 1V, removing the need for external  
resistors. Both channels have rail-to-rail inputs and  
outputs, a gain of one, and are AC coupled with the  
use of one capacitor.

Replacing  
a
discrete buffer solution with the  
LMH2180 provides many benefits: simplified board  
layout, minimized parasitic components, simplified  
BOM, design durability across multiple applications,  
simplification of clock paths, and the ability to reduce  
the number of clock signal generators in the system.  
The LMH2180 is produced in the tiny packages  
minimizing the required PCB space.
