NS LMX2541SQ2690E/NOPB

频率合成器（RF）是时钟时钟

Overview

The LMX2541SQ2690E/NOPB is an ultra low-noise frequency synthesizer which integrates a high performance delta-sigma fractional N PLL, a VCO with fully integrated tank circuit, and an optional frequency divider. The PLL offers an unprecedented normalized 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. The PLL can also be configured to work with an external VCO.

The LMX2541SQ2690E/NOPB is a monolithic integrated circuit, fabricated in a proprietary BiCMOS process. Device programming is facilitated using a three-wire MICROWIRE interface that can operate down to 1.6 volts. Supply voltage ranges from 3.15 V to 3.45 V. The LMX2541SQ2690E/NOPB is available in a 36-pin 6-mm × 6-mm × 0.8-mm WQFN Package.
