Description

The LMX2492QRTWRQ1 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 LMX2492QRTWRQ1 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 LMX2492QRTWRQ1 can be read back.

The LMX2492QRTWRQ1 can be operated by 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.
