LMX2470 Description
The LMX2470 is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integerN PLL. The device is fabricated using TI’s advanced BiCMOS process. With delta-sigma architecture, fractional spur pensation is achieved with noise shaping capability of the delta-sigma modulator and the inherent low pass filtering of the PLL loop filter.
