LMX2492 datasheet


Description :

The LMX2492, LMX2492-Q1 is a low noise 14 GHz wideband delta-sigma fractional N PLL with ramp and chirp generation. It consists of a phase frequency detector, programmable charge pump, and high frequency input for the external VCO.

The devices supports a broad and flexible class of ramping capabilities, including FSK, PSK, and configurable piecewise linear FM modulation profiles of up to 8 segments. It supports fine PLL resolution and fast ramp with up to a 200 MHz phase detector rate. The devices allows any of its registers to be read back. The ICs can operate with a single 3.3 V supply. Moreover, supporting up to 5.25 V charge pump can eliminate the need of external amplifier, leading to a simpler solution with improved phase noise performance.

Features :

1. 500 MHz – 14 GHz Wideband PLL

2. Versatile Ramp / Chirp Generation

3. 200 MHz Max Phase Detector Frequency
