- The LMX2531 is a low power, high performance frequency synthesizer system which includes a fully integrated delta-sigma PLL and VCO with fully integrated tank circuit. The third and fourth poles are also integrated and also adjustable. Also included are integrated ultra-low noise and high precision LDOs for the PLL and VCO which give higher supply noise immunity and also more consistent performance. When combined with a high quality reference oscillator, the LMX2531 generates very stable, low noise local oscillator signals for up and down conversion in wireless communication devices. In the system, the LMX2531 is controlled by FPGA. It outputs a 1500MHz clock signal through programmed eleven 24-bit registers with Verilog HDL. The signal is very suitable to be used as the sampling clock of ADC in high speed acquisition system for it has the characteristics of low jitter and high stability.
