The LMX2492/92-Q1 is a low noise 14 GHz wideband delta-sigma fractional N PLL with ramp
and chirp generation. It consists of a phase frequency detector, programmable charge pump, and high
frequency input for the external VCO. The LMX2492/92-Q1 supports a broad and flexible class of
ramping capabilities, including FSK, PSK, and configurable piecewise linear FM modulation profiles
of up to 8 segments. It supports fine PLL resolution and fast ramp with up to a 200 MHz phase
detector rate. The LMX2492/92-Q1 allows any of its registers to be read back. The LMX2492/92-Q1 can
operate with a single 3.3 V supply. Moreover, supporting up to 5.25 V charge pump can eliminate the
need of external amplifier, leading to a simpler solution with improved phase noise performance.
