Description
The Si5338 is a high-performance, low-jitter clock generator capable of synthesizing any frequency on each of the device’s four output drivers. This timing IC is capable of replacing up to four different frequency crystal oscillators or operating as a frequency translator. Using its patented MultiSynth technology, the Si5338 allows generation of four independent clocks with 0 ppm precision. Each output clock is independently configurable to support various signal formats and supply voltages. The Si5338 provides low-jitter frequency synthesis in a space-saving 4 x 4 mm QFN package. The device is programmable via an I2C/ SMBus-compatible serial interface and supports operation from a 1.8, 2.5, or 3.3 V core supply. I2C device programming is made easy with the Clock Builder Desktop software.
