LMX2541 Integrated PLLatinum PLL+VCO Family

LMX2541 Family PLL+VCO

The LMX2541 family is the world's lowest noise integrated frequency synthesizer. Featuring the world’s lowest noise phase-locked loop (PLL) with bypass-able integrated VCO, the LMX2541 provides less than 2 milli-radians (mrad) root-mean-square (RMS) noise at 2.1 GHz and 3.5 mrad RMS noise at 3.5 GHz, outperforming the nearest competitor by 10 dB in both in-band PLL noise and spurious performance.

The LMX2541 is well-suited for local oscillator (LO) applications in next-generation basestation radio transceivers such as Long-Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), and multi-standard radios. When paired with the LMK04000 clock jitter cleaner, the LMX2541 significantly improves system error vector magnitude (EVM), resulting in enhanced receiver sensitivity and transmitter spectral purity.

Features

• Normalized PLL phase noise of -225 dBc/Hz
• Ultra-low RMS noise and spurs
• Wide frequency range 31.6 MHz to 4 GHz
• Internal VCO can be bypassed for use with external VCO
