The ICS4231M-03LFT is clock generator, phase-locked loop (PLL) and frequency synthesizer that provides both a pulse frequency and pulse width modulated (PFM) output. It is a high performance, low-jitter, low-cost device that can be used in a variety of applications. The ICS4231M-03LFT is a dual modulator device that includes a programmable oscillator and two independent direct digital synthesizers (DDSs). The oscillator can be set to generate a wide-range of pulse frequency up to 150 MHz, while the DDSs can be programmed to generate PFM waveforms with over 8 bits of resolution, for a total of 16 bits of resolution. The device is designed to be programmed and controlled via either a simple serial interface or a variety of digital inputs that can be used to enable/disable the device and control the oscillator and DDS.The ICS4231M-03LFT is ideal for applications such as mobile communications, RF communication systems, optical communication systems, and automotive electronics. It can be used to generate highly accurate clock signals with minimal jitter and filtered output waveforms. It is also useful in applications that require multiphase pulse waveforms and/or wide-range frequency synthesis. The ICS4231M-03LFT has a very low power consumption, with a current draw of only 8.5 mA. This makes it an ideal choice for applications where low power consumption is a priority. The wide-range frequency of up to 150 MHz and the low power consumption make it well suited for applications in mobile phones and other portable devices.The ICS4231M-03LFT is based on a PLL system, with two independent variable frequency dividers. The two dividers can be used to generate the desired clock frequency, while the PLL system maintains precise synchronization between the input clock source and the output clock. The ICS4231M-03LFT also has a built-in temperature compensation circuit that ensures reliable operation even in extreme temperatures. The ICS4231M-03LFT is well suited for applications where low jitter and wide-range frequency synthesis are important, such as in frequency modulated (FM) radio, television and telecommunications systems. It is also ideal for applications such as radar, medical imaging and instrumentation. In summary, the ICS4231M-03LFT is a low-cost, high-performance clock generator, PLL and frequency synthesizer that is well-suited for a wide range of applications. Its low power consumption and wide-range frequency make it well-suited for applications in mobile phones and other portable devices. Its temperature compensation circuit ensures reliable operation even in extreme temperatures, and its built-in PLL system provides precise synchronization for accurate clock signals.
