The SI5338M-B05183-GMR is a member of the Si536x family of fractional-N frequency synthesizers designed to produce high performance clock outputs with phase noise performance suitable for digital timing applications. With integrated voltage-controlled oscillator (VCO) and digital phase-locked loops (PLLs), these devices require minimal external components for designing clock generators with exceptional output jitter performance. They are ideal for a wide variety of timing applications in the Industrial Automation, Networking/Storage, Military/Aerospace, Broadcast and Communications markets.

The SI5338M-B05183-GMR is a low power device that uses a unique dual divider architecture. It includes the ability to process up to five incoming reference frequencies and two differential clock outputs. It is capable of generating frequencies from 0.25MHz to 800MHz from a single 14-bit programmable reference input. The output frequency can be programmed with dynamic tuning capability.

The SI5338M-B05183-GMR also features a wide-range of integrated voltage-controlled oscillator (VCO) output options. These include a differential LVPECL output, a single-ended CMOS output, or both. The CMOS output has an integrated power down mode and is configurable for either positive or negative logic.

The dual divider architecture ensures very low jitter performance on the output clock signal. The jitter tolerance (JTOL) of the device can be programmed to optimize the jitter performance of the output clock. The SI5338M-B05183-GMR also features integrated glitch filters to reduce undesirable data packet jitter and reduce EMI emissions.

The SI5338M-B05183-GMR also includes an automatic calibration feature which helps to minimize the cycle-to-cycle jitter of the output clock. This feature uses a feedback loop to make sure the output frequency matches the desired frequency, even if the reference frequency varies. The device is also capable of locking to an arbitrary frequency, allowing for more precise tuning.

The SI5338M-B05183-GMR supports both conventional Spread Spectrum and Programmable Spread Spectrum techniques. Spread Spectrum enables the designer to reduce the peak-to-average ratio of the output frequency, thus reducing EMI emission. It also increases the immunity of the device to noise present in the system.

The SI5338M-B05183-GMR is a complete clock generator solution that is ideal for applications where precise and low jitter clock signals are required. With integrated spread spectrum capabilities, the SI5338M-B05183-GMR is an excellent choice for noise-sensitive applications. The device is also well-suited for timing applications in the Industrial Automation, Networking/Storage, Military/Aerospace, Broadcast and Communications Markets.
