The LMX2337MX is a highly advanced 3-V to 3.6-V frequency synthesizer integrated circuit. It is designed for use in applications requiring precise signal generation, such as digital radio receivers. The LMX2337MX is a cost-effective, low power, and reliability-enhanced solution for RF signal generation within digital radio systems.

The LMX2337MX is a PLL-based frequency synthesizer that utilizes an integrated digital phase-locked loop and is one of the most advanced frequency synthesizers available. It has an enhanced digital phase detector, a low power consumption design, and an integrated frequency-jitter correction algorithm. The LMX2337MX enables low frequency start up and tracking, low power consumption, low phase noise and fast switch over times.

The LMX2337MX operates in a variety of frequency ranges, including 2.4 GHz and 5 GHz. This frequency synthesizer is designed for radio receivers operating in these bands. In these designs, the LO frequency is derived from an external frequency reference and the RF is adjusted to match the channel frequency. The LMX2337MX\'s ability to precisely adjust the LO frequency to the channel frequency, as well as quickly switch between channels, reduces receiver power consumption and makes it an attractive choice for radio receivers.

The LMX2337MX frequency synthesizer utilizes a proprietary digital phase-locked loop architecture that incorporates a simple linear phase register, a gated latch divider and a closed loop synthesizer block. This architecture allows the frequency synthesizer to quickly settle to the reference frequency while requiring minimal loop settling time. The phase detector optimizes the linearity of the phase errors and the frequency tracking loop provides high cycle-to-cycle jitter metrics. The digital PLL also includes a programmable loop bandwidth, a programmable dwell time and adjustable VCO frequency ranges.

The LMX2337MX frequency synthesizer is designed for use in a wide variety of applications, including radio applications like digital radio receivers, base stations, and mobile radio systems. It is an ideal solution for those looking for a reliable, cost effective, and low-power frequency synthesizer for their radio receiver application. The LMX2337MX is designed for easy integration, featuring on-board loop filter as well as integrated charge pump and loop control logic. This helps to reduce design cost and time, allowing engineers to quickly complete their design.

In summary, the LMX2337MX is an advanced 3-V to 3.6-V frequency synthesizer integrated circuit, designed for use in high performance digital radio receivers. It is a low power and cost effective solution for creating precisely generated signals. The LMX2337MX utilizes an integrated digital phase-locked loop and an advanced digital phase detector, enabling low start up and tracking times, low power consumption, and low phase noise. It is also designed for easy integration and is a great choice for radio receiver applications.
