SI53301/4-EVB

The Skyworks Solutions SI53301/4-EVB evaluation board is used for evaluating the Si533xx family of low-jitter clock buffers and level translators. As shipped, this board has the Si53301 device installed, but it can be used to evaluate any Si533xx device due to common input circuits and output drivers.

This evaluation board supports multiple supply voltages including 1.8 V, 2.5 V, and 3.3 V for VDD, VDDOA, and VDDOB. VDD powers the input buffers, mux, and dividers, while VDDOA and VDDOB power the output drivers. The board features SMA connectors for easy access to test and evaluate the clock buffer functionality.

The Si53301 provides pin-selectable clock output signal format, drive strength control, optional clock division, and per-bank output enable. The Si53304 offers similar features with individual output enable pins for each clock output. This evaluation board facilitates the assessment of these features and the overall performance of the Si533xx family.

Features of the evaluation board include power supply connections, jumpers for output signal format and clock selection, and jumpers for self-biasing CMOS single-ended inputs. This design allows for comprehensive testing and characterization of the clock buffer ICs.
