Working Principle

The SI5350A-B07782-GM is a complete, low-power clock generator that features a single non-integer programmable PLL (phase-locked loop). The PLL\'s reference input is designed to accept any input frequency from 10 kHz to 200 MHz, including those that are integer and non-integer multiples of reference frequencies, such as 1.001 GHz and 1.047 GHz. It can also generate multiple output frequencies from 50 MHz to over 7.3 GHz with only a small number of components.

The PLL generates two outputs—one for a high-frequency. The second output is used for synthesizing frequencies that are multiples of the reference frequency. Its low output jitter of 200 fs rms and its low power consumption make it ideal for applications that require high performance with low-cost components. It also offers high integration and flexibility.

The SI5350A-B07782-GM boasts a wide range of frequency options thanks to its programmable N-divided and M-divided outputs. It also includes a programmable loop bandwidth selection, allowing users to adjust the frequencies of the PLL\'s output to match specific application needs. Additionally, the SI5350A-B07782-GM\'s slew-controlled output enables flexible frequency selection and low-skew output timing.

The SI5350A-B07782-GM\'s programmable loop bandwidth selection feature allows it to perform rapid lock acquisition, providing fast and accurate PLL synchronization. Its output-divide ratio can also be precisely adjusted, allowing for efficient high-performance locks with minimal jitter.
