1. Functional Block Diagram
Figure 1 highlights the main features of the EVB. The onboard MCU is responsible for programming the Si535x
timing IC, measuring the device's current consumption reported in ClockBuilder™ Desktop, managing power, and
controlling status LEDs. VDD and VDDO jumpers allow the option to choose between 2.5 V and 3.3 V or to power
2
the device with external supplies (see “2. Jumpers” for details). I
C jumpers allow the Si535x to be disconnected
2
2
from the I
C bus to allow external control from another I
C master.
The device can run in stand-alone asynchronous mode using the onboard 27 MHz XTAL (Y1), or it can be
synchronized to an external clock using the CLKIN SMA connector or TP39/TP40.
