The Texas Instruments LMC568CM/NOPB is a clock generator and phase-locked loop (PLL) that has a highly configurable output frequency that can be programmed using the built-in on-board frequency synthesizer. This versatile device is ideal for use in any application that requires a frequency control or synchronization, from portable consumer electronics to industrial control systems.The LMC568CM/NOPB is a high-performance monolithic device that can generate a wide range of output frequencies from 0.01 Hz to 200 MHz. It operates from a 3.3V or 5V supply and provides low jitter (<1 ps) and fast settling times (<200 ns). It also features integrated operating temperature range and high isolation from power supply noise.At its core, the LMC568CM/NOPB uses a PLL that has two inputs and uses two reference frequencies to generate a desired output frequency. The PLL phase detector compares the input reference frequencies and generates an error signal that is then used to adjust the voltage to the VCO, or voltage-controlled oscillator. This voltage then determines the output frequency of the VCO, which is ultimately determined by the input reference frequencies.To generate an accurate and stable output frequency, the LMC568CM/NOPB has a frequency synthesizer that allows user-programmable frequency tuning. This frequency synthesizer is able to precisely adjust both the reference frequency inputs and the VCO in order to achieve a desired output frequency. Additionally, the LMC568CM/NOPB provides a programmable divider, or prescaler, so that a frequency range starting from 0.01 Hz and up to 200 MHz can be achieved.Overall, the Texas Instruments LMC568CM/NOPB is an ideal device for applications that need precise and repeatable frequency control and synchronization, including consumer electronics, radio equipment, communication networks, and automotive systems. With its adjustable output frequency, integrated operation frequency range, low jitter, and fast settling time, the integrated frequency synthesizer can easily and quickly generate any desired frequency.
