Part Number : LMX2492
Function : 500MHz to 14GHz Wideband, Low Noise Fractional N PLL with Ramp/Chirp Generation
Package : WQFN (RTW) 24 Pin type
Maker : Texas Instruments
Pinouts : 
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 LMX2492 / LMX2492-Q1 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 LMX2492/92-Q1 allows any of its registers to be read back. The LMX2492/92-Q1 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.
