LMX2571 Low-Power Synthesizer

Texas Instruments LMX2571 Low-Power Synthesizer is a low-power, high-performance, wideband PLLatinum™ RF synthesizer. This device integrates a delta-sigma fractional N PLL, multiple core voltage-controlled oscillator (VCO), programmable output dividers, and two output buffers. The VCO cores work up to 5.376GHz resulting in a continuous output frequency range of 10MHz to 1344MHz. This synthesizer can also be used with an external VCO. To that end, a dedicated 5V charge pump and an output divider are available for this configuration. A unique programmable multiplier is also incorporated to help improve spurs. This feature allows the system to use every channel, even if it falls on an integer boundary. The Texas Instruments LMX2571-EP devices have gold bond wires, a temperature range of –55 to +105°C, and an SnPb lead finish.
