Clock/Timing - Application Specific is used in many applications such as medical, industrial, aerospace, and communications. The SI5338P-B03840-GMR is a clock/timing PLL device specifically designed for these applications. The device provides synchronous and asynchronous outputs with low jitter and tight timing controls allowing for flexible solutions in a compact package. It is also available in various packages and configurations depending on the end application.

A PLL (Phase Locked Loop) is a system used to generate mechanical synchronization on a rotating device. The PLL contains a phase detector input associated with an oscillator of constant frequency. The output frequency is always an integer multiple of the reference clock. The SI5338P-B03840-GMR is a zero-delay feedback PLL with frequency synthesis that is controlled using a single differential input.

The SI5338P-B03840-GMR uses a “burst-mode” pulse width modulator to generate programmable clock outputs with low jitter as low as 25ps RMS. This allows for fast configuration updates, which are necessary for communication systems and other demanding applications. With selectable input and output frequency ratios, the SI5338P-B03840-GMR is well suited for synchronization in communications, military, aerospace and other timing applications.

The device contains a phase detector with an input clock range of 0.5 to 40 MHz and a reference frequency that can span up to 330 MHz. It also includes a programmable divider to scale the input frequency for synchronization purposes. An integrated loop filter provides additional flexibility and linear tuning, resulting in excellent phase noise performance.

The SI5338P-B03840-GMR provides synchronized and asynchronous outputs at up to 2.2 GHz, including sine wave, square wave, duty cycle, and clock output modes. There are also two outputs to provide a duty cycle output enabling the device to switch from a low to a high voltage state. Additionally, flexible output control and user defined output divider functions provide for greater control and flexibility.

Other features of the SI5338P-B03840-GMR include an integrated PLL power-down mode and a programmable power supply start-up delay. The device is packaged in an 8-lead SOIC package and powered by either a single 5V or 3.3V supply. The device is available in various packages and configurations under the GMR-grade category – which meets stringent medical and aerospace industry standards.

The SI5338P-B03840-GMR is a versatile clock/timing PLL for use in medical, industrial, aerospace, and communications systems and applications. Low jitter, tight timing controls, synchronization, integrated PLL power-down and programmable power supply start-up delay make this device an attractive solution for these applications. The device is fully tested and qualified, offering years of reliable operation.
