LMX2582 Core Board 20-5500MHz Low Phase Noise Wideband Frequency Source Module Integrated PLL with STM32 Main Control Board

LMX2582 Core Board 20-5500MHz Low Phase Noise Wideband Frequency Source Module Integrated PLL with STM32 Main Control Board

Description:
- LMX2582 is a low-noise, broadband RF PLL with integrated VCO, supporting a frequency range of 20MHz to 5.5GHz. This device supports both fractional N and integer N modes, with a 32-bit decimal divider that provides precise frequency selection. Its integrated noise is 47fs noise (for 1.8GHz output), making it an ideal low-noise source. This device integrates top-notch PLL and VCO integrated noise with an integrated low-voltage linear regulator (LDO), eliminating the need for multiple discrete components in high-performance systems.

- This device can accept input frequencies up to 1.4GHz, and when combined with a frequency divider and programmable low-noise multiplier, it can flexibly set the frequency. Adding programmable low-noise multipliers can help users remove the impact of integer boundary spikes. In fractional N mode, the device can adjust the output phase to 32-bit resolution. For applications that require fast frequency switching, this device supports a fast calibration option with a time consumption of less than 25us.

- It is possible to achieve this performance using a 3.3V power supply. This device supports 2 differential outputs, which can also be flexibly configured as single ended outputs. Users can choose to program one output from the VCO and the other output from the channel distributor. If you do not want to use it, you can disable each output separately.
