Texas Instruments LMH2180SDE/NOPB

Description
The LMH2180 is a highspeed dual clock buffer designed for portable communications and applications requiring multiple accurate multiclock systems. It integrates two 75 MHz lownoise 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.
Unique technology and design provide 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 batterypowered 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/us internal slew rate with independent shutdown and duty cycle precision. Each input is internally biased to 1 V, removing the need for external resistors. Both channels have railtorail inputs and outputs, a gain of one, and are AC coupled with the use of one capacitor.
