Shop the Texas Instruments LMX2370TM Clock Generator Series for the highest level of frequency flexibility for the generation and distribution of clocks in applications requiring low jitter performance. The LMX2370TM family consists of over 20 device variants with multiple output formats and enhanced clock generation capabilities.

This series of Clock Generators are well suited for high-bandwidth systems that require multiple clock frequencies. They provide an excellent combination of capability and integration to meet the requirements of a wide variety of applications such as Communications, Computing, Storage, Networking and Automotive. The devices also provide the flexibility to choose between multiple output formats and can generate frequencies up to 300MHz.

The LMX2370TM family is a cost effective solution that provides high-performance clock generation with low jitter and flexible features. The series features a low-noise programmable PLL, integrated voltage controlled oscillator (VCO), and four global buffered outputs. The programmable PLL allows the user to easily modify the reference clock, VCO range, charge pump current, and output frequency. Additionally, the output configuration can be programmed between single-ended, differential, and HCSL outputs.

A key feature of the LMX2370TM series is their low phase jitter (pj). Phase jitter is the cumulated effect on signal integrity caused by the clock ’s inherent imperfections, such as phase noise, reference noise, fractional-N spurs, and modulation. The total phase jitter of the LMX2370TM series is typically only 0.27 ps RMS, making this series the best choice for applications that require the highest level of performance and frequency flexibility. This makes the LMX2370TM series the ideal choice for clock generation and distribution in any number of high-performance systems.

The working principle of the LMX2370TM series is straightforward. It accepts a reference clock signal and uses a phase-locked loop (PLL) to generate an output clock signal of a higher or lower frequency. The output clock signal is then sent to the integrated output buffers to ensure that there is no propagation delay or data skew. The PLL is controlled by a programmable divider and the charge pump current can be programmed to match the loop filter components. Additionally, the reference input clock frequency can be programmed to optimize the performance of the device.

The performance and features of the LMX2370TM series make it an ideal choice for a wide range of clock generation and distribution applications. It provides a low-noise programmable PLL and a wide range of frequencies up to 300MHz with high precision and low jitter performance. The series also provides multiple output formats and can be easily configured to provide the desired output frequency. Furthermore, the integrated VCO and global output buffers make the series an attractive solution for high-bandwidth applications requiring multiple clock frequencies.
