= 167 MHz, commercial temperature range) The performance of the CDCE906 and the CDCE706 is equal, but the CDCE906 has a limited output frequency and temperature range for operating. Because of this, the CDCE706 is used on this board for evaluation purposes. -

(outputs disable to low, outputs 3-state, power down, PLL bypass, etc). The CDCE906/CDCE706 has three power supply pins, VCC, VCCOUT1, and VCCOUT2. VCC is the power supply for the device. It operates from a single 3.3-V supply voltage. VCCOUT1 and VCCOUT2 are the power supply pins for the outputs. - Page 7 Introduction Related Documentation From Texas Instruments • CDCE906, Programmable 3-PLL Clock Synthesizer/Multiplier/Divider data sheet (SCAS814) • CDCE706, Programmable 3-PLL Clock Synthesizer/Multiplier/Divider data sheet (SCAS815) SCAU016B – August 2006 – Revised August 2007 CDCE906/CDCE706 Performance Evaluation Module Submit Documentation Feedback...

Default setting: J12 and J10 are not used. Note: S0 and S1 are logic high due to their internal pull-up resistors if J10 and J12 are not used.

However, the output load is too low if Y0–Y5 is connected directly to a 50 Ω parallel termination. This results in a violation of the ac-parameters mentioned in the data sheet.

Page 11: Ti Pro-Clock
TI Pro-Clock™ TI Pro-Clock™ TI Pro-Clock™ is the evaluation software for the CDCE906 and the CDCE706. The software contains the CDCE906-706 SMBus Interface and the CDCE906-706 Programming Assistant. In the future, the software will be expanded for new devices. The software runs under Windows 2000, XP, and XP*64. A quick installation is required prior to use. -

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. -
Page 13: Programming Assistant
The Programming Assistant starts with its own default setup. The default setup of the Programming Assistant is different to the default setup of the CDCE906/CDCE706. This is why, the Programming Assistant has a simple startup setup, which makes it easy to create a new user-defined setup. From this default setup, different parameters can be edited to create a user setup. -
Page 14: Tutorial
This section contains a step-by-step tutorial for creating a user-defined setup and programming the CDCE906/E706. The 27-MHz crystal of the EVM is used for reference. A 64-MHz CPU clock, different audio sample clocks for 24-kHz audio rate, a 27-MHz clock for an MPEG/AC-3 Audio Dec, and an additional 60-MHz clock is provided. -
Page 15: Software Installation
1. Download TI Pro-Clock™ from www.ti.com. 2. Run program setup.exe. 3. Reboot your computer. 4. Run the Software from Start → Programs → Texas Instruments → TI Pro Clock. SCAU016B – August 2006 – Revised August 2007 CDCE906/CDCE706 Performance Evaluation Module... -

The output impedance is probably too small. Enlarge the output impedance as written in section 3.2.5. The CDCE906/CDCE706 register cannot be programmed. What is wrong? Check if the parallel port is connected to your PC and your EVM. Check if all voltages are applied. - Page 17 Panasonic ERJ-2RKF1000X R52, R54 100 kΩ Panasonic ERJ-2RKF1003X CDCE706 CDCE706 SN74LV125 Texas Instruments SN74LV125AD 27 MHz Crystal Epson Toyocom TSX 3225 Stand Off MP32 Screw SCAU016B – August 2006 – Revised August 2007 CDCE906/CDCE706 Performance Evaluation Module Submit Documentation Feedback...
