LMX2331USLBX

LMX2331USLBX is a programmable clock generator designed for high-performance applications in the networking, computing and communications sectors. It enables system designers to create the most complex clock designs quickly and easily. It provides the flexibility to manage multiple clock outputs in a wide range of clock configurations.

The LMX2331USLBX is designed for clock/signal synthesizing and distribution applications. The device provides four high-speed differential PECL outputs, with one output being a programmable frequency synthesis output and the other three outputs operating as outputs of a low-jitter LVCMOS oscillator. The device also includes an additional LVCMOS clock, which is programmable via an I²C interface. The device supports all standard reference clock frequencies and allows the user to program an output frequency to within 1% accuracy.

The LMX2331USLBX supports a wide range of frequency synthesis, including PLL (Phase-Locked Loop) frequency synthesis, Fractional frequency synthesis, and Multiplier/Divider frequency synthesis modes. The PLL mode is suitable for creating higher frequency synthesized clocks from lower frequency components (e.g. from 50MHz to 400MHz). The fractional frequency synthesis mode is suitable for creating decimals in frequencies that would otherwise not be possible (e.g. from 40MHz to 40.9MHz). The multiplier/divider mode is suitable for creating lower frequencies from a higher frequency reference. This technique can be used to reduce power and jitter in many applications.

The LMX2331USLBX can also be used as an oscillator and clock generator. The device includes an internal 32MHz oscillator, which can be used as the main reference source. This oscillator can be used to generate clocks at multiple frequencies from one input without any additional external components. The device also includes three LVCMOS clock generators, which can be used to generate frequencies from 32kHz to 400MHz. These are designed for use in applications where the output signal needs to be low jitter and very accurate.

The LMX2331USLBX is designed for easy use and flexibility. It can be programmed using an I²C interface, allowing quick and easy configuration of the output clock frequencies and settings. The device is also RoHS compliant, making it suitable for use in a wide variety of end applications.

In summary, the LMX2331USLBX is an ideal solution for creating complex clock designs quickly and easily. It supports multiple high-speed differential PECL outputs and can generate frequencies from 32kHz to 400MHz. It is easy to use and flexible, making it suitable for a vast range of applications.
