National Semiconductor has released a new low-noise, fully integrated frequency synthesiser. The PowerWise LMX2541 provides less than 2 milliradians (mrad) rms noise at 2,1 GHz and 3,5 mrad rms noise at 3,5 GHz and is well suited for local oscillator (LO) applications in base-station radio transceivers such as LTE, WiMAX and multistandard radios. When paired with the LMK04000 clock jitter cleaner, the LMX2541 improves system error vector magnitude (EVM), resulting in enhanced receiver sensitivity and transmitter spectral purity.
The LMX2541 is offered in a family of six devices covering a wide range of frequencies from 31,6 MHz to 4000 MHz. It features a fully integrated, ultra low-noise delta-sigma fractional-N PLL, voltage-controlled oscillator (VCO), divider and output driver. The PLL offers a normalised noise floor of -225 dBc/Hz and can be operated with up to 104 MHz of phase-detector rate (comparison frequency) in both integer and fractional modes. It can also be configured to work with an external VCO. The LMX2541 offers advanced features such as programmable output power, digital frequency-shift-keying (FSK) modulation, FastLock mode with cycle-slip reduction and a low-noise, integrated-input crystal oscillator circuit.
The synthesiser integrates the necessary low-dropout (LDO) regulators and output-driver matching network to provide high supply noise immunity and consistent performance, while reducing the number of external components. The LMX2541’s supply voltage range is 3,15 V to 3,45 V and device programming is facilitated using a three-wire MICROWIRE bus interface that can operate down to 1,8 V.
