UG301: Si5332-12EX-EVB User’s Guide
The Si5332-12EX-EVB is used for evaluating the Si5332 Low Jitter Any-Frequency
Clock Generator. The Si5332 uses the patented Multisynth technology to
generate up to twelve independent clock frequencies each with 0 ppm synthesis
error. The Si5332-12EX-EVB has three independent ™input clocks. The Si5332
-12EX-EVB can be controlled and configured using the Clock Builder Pro ™(CB
Pro
) software tool.
EVB FEATURES
- Powered from the USB port or external power supply.
- Onboard 25 MHz XTAL allows the free-run mode of operation on the Si5332 or up to 2 input clocks for synchronous clocking.
- CBPro ™GUI programmable VDD supply allows devices to operate from 3.3, 2.5, or 1.8 V.
- CBPro GUI programmable VDDO supplies allow each of the 10 outputs to have its own power supply voltage selectable from 3.3, 2.5, or 1.8 V.
- CBPro GUI-controlled voltage, current, and power measurements of VDD and all VDDO supplies.
- SMA connectors for input and output clocks.
Functional Block Diagram
Below is a functional block diagram of the Si5332-12EX-EVB. This EVB can be
connected to a PC via the main USB connector for
programming, control, and monitoring. See section “2. Quickstart” or section
“7. Installing CBPro Desktop Software” for more information.
Si5332 CBPro™
The Si5332 is intended to be part of the CBPro software and this initial software release “showcases” that trait. This software contains:
- An EVB GUI that communicates and controls the EVB by allowing the user to set VDD supplies
- The ability to modify frequency plan (from the starting point CBPro file provided with this limited release) from an existing CBPro
file.
Si5332-12EX-EVB Schematics
The schematic and layout files are provided in here: schematics and layouts.
Please review the files, especially the DUT page in order to get familiar with
using the EVB through CBPro™
Si5332 CBPro.™
EVB GUI
The EVB GUI can be used to communicate the part for register access:
The first page shows the board’s identity.
The other pages for register access, VDD control, and GPIO control.
