LMV112

40 MHz Dual Clock Buffer

General 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 solu-

tions. This device enables superb system operation between

the base band and the oscillator signal path while eliminating

crosstalk.

National Semiconductor’s unique technology and design de-

liver accuracy, capacitance and load resistance while in-

creasing the drive capability of the device. The low power

consumption makes the LMV112 perfect for battery applica-

tions.

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 shut-

down and duty cycle precision. The patented analog circuit

drives capacitive loads beyond 20 pF. National’s proven

biasing technique has 1V centering, rail-to-rail input/output

unity gain, and AC coupled convenient inputs. These inte-

grated cells save space and require no external bias resis-

tors. National’s rapid recovery after disable optimizes perfor-

mance 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.

−40˚C to 85˚C

Applications

n 3G mobile applications

n WLAN–WiMAX modules

n TD_SCDMA multi-mode MP3 and camera

n GSM modules

n Oscillator modules

The LMV112 is a proven replacement for any discrete cir-

cuitry and simplifies board layout while minimizing related

parasitic components.

The LMV112 is produced in the small LLP package which

offers high quality while minimizing its use of PCB space.

National’s advanced packaging offers direct PCB-IC evalu-

ation via pin access.
