LMX2492EVM
概覽
The LMX2492EVM supports evaluation of the LMX2492 and LMX2492-Q1 which is an ultra-low noise 14 GHz wideband RF PLL with ramp/chirp generation, consisting of a delta-sigma fractional N PLL, phase detector, programmable 5V charge pump and high frequency divider for the VCO. The LMX2492 supports a broad and flexible class of ramping capabilities. It is able to generate FSK and PSK modulation, triangular, sawtooth and customizable ramp pattern. In addition, it supports fine PLL resolution and fast ramp with up to 200 MHz phase detector rate. The LMX2492 allows any of its registers to be read back through a 3-wire interface, and includes digital lock detect, programmable charge pump current and output power. The LMX2492 can operate with a single 3.3V supply. Moreover, the 5V charge pump eliminates the need of external op-amp, leading to improved phase noise performance.
