Application Field

The SI5338J-B05506-GM can provide a wide range of clock frequency outputs and programmable jitter performance (pJ). It is ideal for applications requiring low jitter clock and high noise immunity, with the help of on-chip EMI filters and jitter attenuators. This device can be used in systems such as Network Processors, Audio/Video Codecs, Communication Controllers, Industrial Controls, Automotive Control Units, and Aerospace Applications. In addition, it can be used to generate reference clocks for ADC/DAC modules in industrial and automotive applications, such as motor control systems, factory automation and in-vehicle infotainment systems.

Working Principle

The SI5338J-B05506-GM integrates a PLL, on-chip EMI filters, and jitter attenuators to generate a high quality clock from the reference oscillator input. This device can generate 24 different clock frequencies from a single reference clock, using its 24 different PLLs. The 24 different clock frequencies are programmable via the SPI or I2C interface, allowing for flexibility in different application fields. The device can also provide jitter performance down to 1pJ, allowing for accurate clock generation. The on-chip EMI filters also help reduce EMI radiation and enable the device to operate in noisy environments.
