Main Screen

The main screen of the CDCE906/CDCE706 SMBUS interface as shown in

control to all programmable features of the CDCE906/CDCE706. All programmable PLL parameters,

like divider settings, SSC settings as well as all input and output settings, can be controlled. Clicking

the write register button transfers the setup to the CDCE906/CDCE706EVM. The parameter byte

selects if the whole setup (all bytes) or only the selected byte will be updated in the

CDCE906/CDCE706 control register.

By selecting auto write in the upper right corner, the CDCE906/CDCE706 SMBus control register gets

an update after each change in the setup of the CDCE906-706 SMBus Interface. If graph ser data is

selected, the bit pattern of SCLK and SDATA is shown on a screen.

Click read register to load the current control register setup of the CDCE906/CDCE706 into the SMBus

Interface. The write EEPROM button updates the CDCE906/706 control register and writes the

updated control register contents into the EEPROM.

After the SSC settings were changed, PLL 2 must get a reset by setting the PLL into bypass mode for

a short time. This is done automatically by the SMBus interface. Due to this, there will be multiple write

cycles on the SMBUS after pressing the write register or write EEPROM button.

A yellow write LED indicates an active writing cycle. If the LEDs write error or read error are switching

from green to red, a write/read error occurred. Check the EVM and the parallel cable and try again.

A Bit Viewer is available in the menu bar. This feature shows the current setup of the SMBus Interface

bit per bit. This allows an easy evaluation of the register setting that is currently set in the SMBus

interface.

It is possible to lock the EEPROM permanently. This avoids undesirable reprogramming of the

EEPROM. Clicking EEPROM→ EEPROM lock in the menu bar permanently locks the EEPROM. After

locking the EEPROM, it cannot be unlocked.

After pressing the Verify Register button (also located in the menu bar), the current SMBus Interface

setting is compared bit-wise with the CDCE906/CDCE706 control register that is connected to the PC.

All bits of the control register that are different to the SMBus Interface setting are shown in a table. The

bits, which show either 0 or 1, represent the control register setting of the CDCE906/CDCE706.

Click Programming Assistant in the menu bar to switch to the CDCE906-706 Programming Assistant,

which helps to create a setup for the CDCE906/CDCE706 by choosing the input and output settings.

Save/Load Setup

Saving and loading the setup of the CDCE906-706 SMBus Interface can be done in four different ways.

Click File, and select one of the following options to save or load the current setup.

1. Save Setup/Load Setup - Saves/loads the setup as/from an encrypted file.

2. Export *.txt/Import *.txt - Exports/imports the setup as/from a text file. Use this format if you want to

view the setup with a text editor later.

3. Export *.csv/Import *.csv - Exports/imports the setup as/from a comma-delimited file. Use this format if

you want to view the setup with Microsoft™ Excel later

4. Export Intel Hex *.hex/Import Intel Hex *.hex - Exports/imports the setup as/from Hexadecimal Object

File Format. Usually programmers can directly read-in this file format.

5. Configuration Code Release Sheet - Use this option if you want to order factory-programmed

EEPROM specials of the CDCE906/CDCE706. Contact your regional marketing or sales

representative for further information.
