LMX2316TMX/NOPB Ultra-Low-Noise PLL Frequency Synthesizer IC 1.2GHz
The LMX2316TMX/NOPB is a high-performance, ultra-low-noise phase-locked loop (PLL) frequency synthesizer from Texas Instruments (TI), designed for precision timing applications in wireless communication, radar, and test/measurement systems. Built on TI's advanced PLLatium™ architecture, this device integrates a voltage-controlled oscillator (VCO), phase frequency detector (PFD), charge pump, and fractional-N divider in a compact 16-pin TSSOP package (6.4mm x 5mm). It supports frequency synthesis from 300MHz to 6GHz with a phase noise floor as low as -230dBc/Hz (normalized), making it ideal for demanding applications requiring minimal jitter and high spectral purity, such as 5G NR, satellite communication, and atomic clocks. The LMX2316TMX/NOPB also features programmable output power (-16dBm to +5dBm) and fast settling time (<10μs), enabling rapid frequency hopping in software-defined radios (SDRs) and frequency-agile systems.
The LMX2316TMX/NOPB Clock Generators is widely adopted in applications demanding high-frequency stability and low noise:
● 5G/6G Communication: Powers base station transceivers, small cells, and massive MIMO systems with ultra-low phase noise for coherent beamforming.
● Satellite & Aerospace: Enables frequency synthesis in GNSS receivers, deep-space communication links, and synthetic aperture radar (SAR) with minimal Doppler shift errors.
● Test & Measurement: Integrates into spectrum analyzers, signal generators, and vector network analyzers (VNAs) for high-accuracy RF calibration.
● Military & Defense: Supports secure communication radios, electronic warfare (EW) systems, and jamming-resistant frequency-hopping spread spectrum (FHSS) protocols.
● Atomic Clocks & Timing: Provides stable reference frequencies for cesium/rubidium clocks and precision time protocols (PTP) in financial networks.
