LMH2180
www.ti.com SNAS419D – JANUARY 2008 – REVISED MARCH 2013 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
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. 1 2 (Typical Values are: VSUPPLY = 2.7V and CL = 10
