Texas Instruments LMX2492EVM Evaluation Module (EVM)
Texas Instruments LMX2492EVM Evaluation Module (EVM) supports the evaluation of the LMX2492 and LMX2492-Q1. The LMX2492 and LMX2492-Q1 are ultra-low noise 14GHz wideband RF PLLs with ramp/chirp generation. These devices consist of a delta-sigma fractional-N PLL, phase detector, programmable 5V charge pump, and high-frequency divider for the VCO. The Texas Instruments LMX2492EVM includes an integrated LDO for the digital supply and a frequency/phase modulation terminal.
