Product Details

The LMX2492RTWR is a 14GHz wideband triangulation integral N-division PLL with ramp and ultra-wideband signal source generation capabilities. It consists of a phase-frequency detector, a programmable charge pump and a high-frequency input for an external VCO.

The LMX2492RTWR supports a wide range and flexible class of ramping capabilities, including FSK, PSK, and configurable piecewise linear FM modulation system configurations of up to 8 segments. It also supports fine PLL resolution and a fast ramp with a phase detector rate up to 200MHz. Any register of the LMX2492RTWR can be read back.

In addition, the LMX2492RTWR can operate on a single 3.3V power supply. Moreover, the support for charge pumps with voltages up to 5.25V can eliminate the need for external amplifiers, thereby obtaining a simpler solution with better phase noise performance.

Application scope

The LMX2492RTWR is widely applied in multiple fields, including:

Frequency Modulated continuous wave (FMCW) radar for automobiles

Military radar

Microwave return stroke

Testing and measurement

Satellite communication

Wireless infrastructure

Sampling clocks for high-speed analog-to-digital converters (ADCs)/digital-to-analog converters (Dacs)
