LMX2487ESQE/NOPB - High-Performance Frequency Synthesizer System from Texas Instruments

The LMX2487ESQE/NOPB is a highly integrated, high-performance frequency synthesizer system from Texas Instruments designed for use in a wide range of RF applications. This device is capable of generating very stable and precise frequencies within the RF spectrum, making it an ideal choice for wireless communications, instrumentation, and aerospace applications.

At the heart of the LMX2487ESQE/NOPB is a dual-modulus prescaler, phase detector, and a programmable charge pump. This combination allows for fine-tuned frequency synthesis with low phase noise and high spurious performance. The device supports a wide frequency range, which is enabled by its multi-core VCO (Voltage-Controlled Oscillator) system and the ability to lock to both integer and fractional frequencies.

The LMX2487ESQE/NOPB also features a digital phase-locked loop (PLL) with a programmable delta-sigma modulator, which ensures that the output frequency is maintained with high accuracy and stability over various conditions. This PLL can be easily configured through a serial interface, which allows for simple integration into a variety of systems.

This device comes in a compact surface-mount package, making it suitable for space-constrained applications. Additionally, the LMX2487ESQE/NOPB operates over a broad temperature range and is designed with power-saving features, including a power-down mode that significantly reduces power consumption when the device is not in use.

Key features of the LMX2487ESQE/NOPB include:

• Low phase noise performance for high-quality signal synthesis
• Wide frequency range support for flexible application use
• Programmable charge pump and phase detector for precise frequency control
• Serial interface for easy programming and control
• Power-down mode for enhanced power efficiency
• Compact surface-mount package suitable for space-constrained environments

Whether you're designing a sophisticated wireless system or require a reliable frequency source for test and measurement equipment, the LMX2487ESQE/NOPB from Texas Instruments offers the performance and flexibility needed to meet the demands of modern RF applications.
