LMK1C1104PWR – TEXAS INSTRUMENTS

The Texas Instruments LMK1104PWR is a low-jitter, multi-output clock synthesizer optimized for high-performance applications demanding precise timing. This device features four independent, low-noise, digitally controlled oscillators (DCOs), each capable of generating frequencies from 500 MHz to 1500 MHz with a typical output jitter of <100 fs RMS. The LMK1104PWR operates from a 3.3V supply voltage, with a typical current consumption of 180mA. Its internal fractional-N architecture allows for fine frequency adjustments, enabling precise synchronization in multi-channel systems. Packaged in a 64-pin, 7x7mm QFN package, it facilitates high-density board layouts._x000D_ _x000D_ Common use cases include high-speed data acquisition systems, advanced radar systems, and high-performance digital signal processing (DSP) applications needing precise clock distribution. Its low jitter and multiple independent outputs eliminate the need for multiple crystal oscillators, reducing board space and cost while simplifying design complexity. The inherent flexibility of its programmable frequency outputs allows designers to adapt the clocking scheme dynamically, making it ideal for systems requiring reconfiguration. However, designers should note the relatively high power consumption compared to some lower-performance alternatives.
