Description

The  Si5338-EVB  is  used  for  evaluating  the

Si5330/34/35/38  family  of  any-frequency,  any-output

clock generators and clock buffers.

EVB Features

Fully powered from a single USB port.

Onboard 25 MHz XTAL allows standalone 

asynchronous operation on the Si5334/35/38.

GUI programmable V

DD 

supply allows device to 

operate from 3.3, 2.5, or 1.8 V.

GUI programmable V

DDO

 supplies allow each of the 

four outputs to have its own supply voltage 

selectable from 3.3, 2.5, 1.8, or 1.5 V

GUI-controlled voltage, current, and power 

measurements of V

DD

 and all four V

DDO

 supplies.

Voltage supply jumpers allow easy access for use of 

external supplies or current measurements.

Input signal jumpers allow external control of pin 

functions such as output enable, phase inc/dec, 

frequency inc/dec, and I2C_LSB.
