40 MHz Dual Clock Buffer
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.
National Semiconductor's 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/?s internal slew rate with independent shutdown 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 integrated cells save space and require no external bias resistors. National's 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 LLP package which offers high quality while minimizing its use of PCB space. National's advanced packaging offers direct PCB-IC evaluation via pin access.
