Product Description

The LMX2592RHAR is a high performance, wire-band PLLatinum RF synthesizer with an integrated voltage-controlled oscillator (VCO) supporting a frequency range of 20MHz to 9.8GHz. This device supports fractional N and integer N modes and has a 32-bit fractional divider, which can provide precise frequency selection. Its phase noise performance leads the industry. The VCO phase noise offset of 1MHz at 6GHz output is -134.5dBc/Hz, the normalized PLL noise base is -231 DBC /Hz, and the normalized PLL flicker noise is -126 DBC /Hz. Integral noise is 49fs RMS jitter (12kHz to 20MHz) ‌.

The LMX2592RHAR can accept an input frequency up to 1.4GHz. Combined with a frequency divider and a programmable low-noise multiplier, the frequency can be flexibly set. The additional programmable low-noise multiplier can help users mitigate the impact of integer boundary spurious. In fractional N mode, the LMX2592RHAR can adjust the output phase to 32-bit resolution. For applications that require rapid frequency changes, the LMX2592RHAR supports a fast calibration option that takes less than 25µs.

This performance can be achieved by using a 3.3V power supply. The LMX2592RHAR supports two differential outputs, and these two outputs can also be flexibly configured as single-ended outputs. Users can choose to program one of them to be output from the VCO (or voltage multiplier), and the other to be output from the channel distributor. If you don't want to use it, you can disable each output separately.
