The Texas Instruments LMX2581SQE/NOPB is a low-noise, wideband frequency synthesizer designed for RF applications. It integrates a delta-sigma fractional N PLL, a core VCO, a programmable output divider, and two differential output buffers.
This device offers a wide output frequency range from 50 MHz to 3.76 GHz. Key electrical specifications include a normalized PLL phase noise of -229 dBc/Hz and 1/f noise of -125 dBc/Hz at a 10-kHz offset from a 1-GHz carrier. The operating voltage is between 3.15 V and 3.45 V, with support for logic levels down to 1.6 V. The operating temperature range is -40°C to 85°C.
The LMX2581SQE/NOPB is highly programmable, allowing users to optimize performance. Features include programmable output power up to +12 dBm at 2700 MHz, programmable fractional modulation, and a programmable 32-level charge pump current. It supports both fractional and integer modes and includes a digital lock detect feature.
Packaged in a 32-WQFN (5x5 mm) with surface mount, this component is suitable for various RF designs requiring precise frequency generation.
