This document describes operation of the Silicon Laboratories Si5xxUC-EVB evaluation board designed to evaluate any of Silicon Labs’ pin-controlled or I2C configurable Si5xxXOs or VCXOs. Three device sites are available to support one of either 5mm x 7mm, 3.2mm x 5mm, or 2.5mm x 3.2mm devices in either 4, 6, or 8 pin configurations. Selector switches make it easy to configure device control pins (pins 1, 2, 7, or 8) for proper operation without the use of jumpers. Similarly, XO device VDD voltage (3.3V, 2.5V, 1.8V) can be selected via switches based on either external +5V (for stand-alone operation) or micro USB sourced +5V USB operation. The EVB also features flexible output termination circuits and PCB layout optimized for superior signal integrity.
Evaluation of any Silicon Labs XO or VCXO (Si51x, Si53x, Si54x, Si55x, Si57x, Si59x) AC coupled differential/single-ended outpu clocks. Voltage control (Vc) port for VCXO evalution. Switch selectable settings. No jumpers. External power or USB powered. Use stand-alone or with our Programmable Oscillator Calculator SW tool
The Si5xxUC-EVB does not come with a pre-installed sample device. You can specify a custom crystal oscillator and create a new part number, or look up an existing product by part number, and order samples starting at the Custom Oscillator Part Number Utility.
