Description

The 8V44N003I is a programmable LVDS synthesizer designed for applications requiring frequency conversion from a differential or single-end reference source. The device is designed to provide optimum performance of low phase noise and high power supply noise rejection over a wide range of output frequencies. Oscillator level phase noise performance is achieved through the use of Renesas' Fourth Generation FemtoClock™ NG PLL technology. Default output frequency settings are factory programmable via a one time programmable ROM while the I2C interface can be used to program the output frequency after power up. A buffered copy of the input reference clock is provided at both LVDS output levels for applications requiring efficient board space utilization.
