DESCRIPTION

The LMV112 is a high speed dual clock buffer

designed for portable communications and accurate

multi-clock systems. The LMV112 integrates two

40 MHz low noise buffers which optimizes application

and out performs large discrete solutions. This device

enables superb system operation between the base

band and the oscillator signal path while eliminating

crosstalk.

Texas Instruments' unique technology and design

deliver accuracy, capacitance and load resistance

while increasing the drive capability of the device.

The low power consumption makes the LMV112

perfect for battery applications.

The robust, independent, and flexible buffers are

designed to provide the customer with the ability to

manage complex clock signals in the latest wireless

applications. The buffers deliver 110 V/μs internal

slew rate with independent shutdown and duty cycle

precision. The patented analog circuit drives

capacitive loads beyond 20 pF. Texas Instruments'

proven biasing technique has 1V centering, rail-to-rail

input/output unity gain, and AC coupled convenient

inputs. These integrated cells save space and require

no external bias resistors. Texas Instruments' rapid

recovery after disable optimizes performance and

current consumption. The LMV112 offers individual

enable pin controls and since there is no internal

ground reference either single or split supply

configurations offer additional system flexibility and

power choices.

The LMV112 is a proven replacement for any discrete

circuitry and simplifies board layout while minimizing

related parasitic components.

The LMV112 is produced in the small WSON

package which offers high quality while minimizing its

use of PCB space. Texas Instruments' advanced

packaging offers direct PCB-IC evaluation via pin

access.
