Connect the CY3676 kit through a USB cable to a PC running Cypress's ClockWizard 2.1 software. The clock device CY29412 can be configured and programmed to generate frequencies with best-in-class performance. 3.1 Theory of Operation The CY3676 EVK offers one differential clock output for evaluation. The CY29412 device is available with a crystal embedded inside the package. There is no requirement for an external clock source or on-board crystal for this kit. The kit is capable of generating fixed 3.3 V, 2.5 V, and 1.8 V voltages from a 5 V USB port. The on-board PSoC 5LP (U7) performs USB-to-I2C conversion. There is one power LED (LED2) driven from the 5 V USB supply and one status LED (LED1) controlled by the PSoC 5LP. The output of the LDO regulator (U8) is configurable (3.3 V, 2.5 V, or 1.8 V) through jumper J13. Note: An additional on-board LDO (U9 - not shown here) generates a fixed 3.3 V supply for the PSoC 5LP in the CY3676 Rev ** EVK. This feature has been changed in CY3676 Rev *A EVK where the PSoC 5LP is directly powered by 5V USB supply. The CY3676 kit revision is printed on the label at the back of the kit box. Figure 3-1 illustrates the block diagram of the CY3676 EVK. Figure 3-1. CY3676 EVK Block Diagram CY3676 Evaluation Kit User Guide, Doc. No. 002-11165 Rev. *A 13 Kit Operation 3.2 Functional Description The differential clock outputs (J6, J7) are driven out on to SMA connectors. The EVK is populated with 50 resistors (R30 and R31) for output termination. The termination options of the differential outputs in the evaluation board are listed in the Hardware chapter. These termination circuits are designed to terminate the output clocks in LVPECL, LVDS, HCSL, LVPECL2, and CML signal types by populating, or by not populating the J5 jumper shunt. Figure 3-2 illustrates the top and bottom view of the CY3676 EVK. Figure 3-2. CY3676 EVK (Top View, Bottom View) CY3676 EVK Top View 3.3 CY3676 EVK Bottom View CY3676 EVK USB Connection The clock device CY29412 on the kit is not loaded with any default configuration. To view and evaluate different configurations on an oscilloscope (or other standard instruments), the clock device must be programmed with the desired configuration. The ClockWizard 2.1 application is required for programming any configuration. Therefore, the kit should be connected (see Figure 3-3) to the PC through the USB connection for programming. Figure 3-3. Kit Connected through USB CY3676 Evaluation Kit User Guide, Doc. No. 002-11165 Rev. *A 14 Kit Operation The kit enumerates as a USB Composite Device as part of the Driver Software Installation on Windows. Figure 3-4.

USB Driver Installation Complete 3.4 Programming the CY29412 The CY29412 device has internal one-time programmable (OTP) nonvolatile memory called eFuse. The device also contains volatile memory that stores an exact copy of the eFuse at the release of reset at power up. The output frequency depends on the configurations in the volatile memory. Writing the entire device configuration in the volatile memory section of a blank device after power up is called Functional Programming. The CY3676 kit is shipped with a blank CY29412 device. This kit can be used to check both the Functional and eFuse Programming of the device using ClockWizard 2.1. See Functional Programming of the CY29412 and eFuse Programming of the CY29412 for details. 3.5 Functional Programming of the CY29412 ClockWizard 2.1 is used for functional programming of the CY29412. A configuration created in ClockWizard 2.1 can be downloaded to the volatile memory section of the device. The example ClockWizard 2.1 projects can be found at the following location: <Install_Directory>\CY3676 Evaluation Kit\<version>\Firmware\Example Projects Configuration profiles generated from these projects can be used to evaluate the CY29412 device on the CY3676 EVK. Refer to Functional Programming for the kit's hardware settings prior to programming. It is recommended that you copy the example projects to another location if you want to make any modifications to the settings so that the default project is retained in the installation directory. CAUTION Before programming the CY3676 EVK through ClockWizard 2.1, it is recommended to go through the Hardware section of this user guide. The mismatch between the hardware settings and the ClockWizard 2.1 configuration may cause potential damage of the EVK. Specifically, the voltage setting on the kit selected with J13 must match the voltage setting within the configuration to be programmed. CY3676 Evaluation Kit User Guide, Doc. No. 002-11165 Rev. *A 15 Kit Operation 3.5.1 Generating and Programming the Device Configuration Profile The ClockWizard 2.1 is used to generate profiles and to perform functional programming of the device. 1.

The non-volatile memory of the CY29412 is a one-time programmable (OTP) eFuse. Any configuration after functional evaluation can permanently be written to the eFuse of the device. See Figure 3-11 for the programming procedure. Configure the device supply to 2.5 V before starting the eFuse programming. Table 4-2 provides the hardware configuration (J13 settings) of CY3676 for setting the device supply to 2.5 V. Figure 3-11. eFuse Programming using ClockWizard 2.1 Evaluate the configuration via functional programming prior to writing a configuration to the eFuse. The configuration cannot be modified or erased once it is written to the eFuse. CAUTION The CY29412 supply must be set to 2.5 V for eFuse programming. Setting the CY29412 supply to any other voltage during eFuse programming will cause potential damage of the device. After the device is eFuse programmed, the user can change the output frequency through the following ways. Note that these changes will revert after a power cycle. Large change programming: Large change programming refers to the case where the frequency is changing more than 500 ppm. Enter the desired frequency in the Profile 0 (MHz) field, and click on Large change update. The device will recalibrate and reconfigure the internal circuit and the output will change to the desired frequency. Small change programming: Small change programming refers to the case where the frequency is changing less than 500 ppm. Enter the desired ppm in the Small change (ppm) field, and click on Small change update. The device will recalibrate and reconfigure the internal circuit and the output will change to the desired frequency. CY3676 Evaluation Kit User Guide, Doc. No. 002-11165 Rev. *A 19 Kit Operation It is recommended that you do not perform any Large change programming operation while performing Small change programming evaluation. In addition, you should not perform multiple Small change programming operations while evaluating Small change programming. CAUTION 3.7 Follow one of these prior to performing Small change programming: Click the Functional Program button if the device is not eFuse-programmed. Apply power cycle if the device is eFuse programmed. Custom Profile Generation ClockWizard 2.1 should be used to generate custom configuration profiles.

Incorrect application of supply or termination voltage will cause performance degradation of the clock output. Prolonged incorrect operation may permanently damage the kit. CY3676 Evaluation Kit User Guide, Doc. No. 002-11165 Rev. *A 22 Hardware 4.2 Board Details 4.2.1 Default Jumper Settings The CY3676 EVK comes with default jumper settings that set the I/O and core supply voltages as 3.3 V. Table 4-3 lists the default jumper settings. Table 4-3: Default Jumper Settings on the Kit Jumper Default Settings Selection J1 Pin 1 and 2 are shorted Power on CY29412. J2 Pin 1 and 2 are shorted VCXO input set to 0 V. J5 Pin 1 and 2 are shorted CY29412 output termination voltage set to 0 V through the 50 termination resistors. J13 Pin 2 and 3 are shorted 3.3 V selected for CY29412. J16 Pin 2 and 3 are shorted OE pin set to 0 V (logic `0'). 4.2.2 Power Settings The only power option of this EVK is 5V that comes from a USB port. The device has the same core and I/O supply voltage. The supply voltage of the device can be selected from on-board generated supplies of 1.8 V, 2.5 V, or 3.3 V. Table 4-2 lists the hardware settings required for power selection. CAUTION The J13 selection must match with the software configuration of the supply voltage. Mismatch between the J13 setting and ClockWizard 2.1 setting may cause incorrect output or reliability problems with the device. 4.2.3 Functional Programming The board should be connected to a PC through a USB connector to configure and program the device. Refer to the CY3676 EVK USB Connection section to learn how to connect the kit to a PC. Figure 4-2 illustrates the programming section of the kit. Figure 4-2. Programming the CY29412 Device The USB interface provides a 5 V power supply. The PSoC 5LP converts the JEDEC profiles into an I2C-compatible format, which is then loaded into the CY29412 clock device. Note: During functional programming, set the power supply of the CY29412 device (hardware settings) the same as in the ClockWizard 2.1 configuration (software settings). Table 4-2 provides the supply settings for CY29412. During eFuse programming, set the power supply of the CY29412 to 2.5V. The Example Projects section provides the examples projects (.cpj files) created in ClockWizard 2.1. CY3676 Evaluation Kit User Guide, Doc.

LED1 USB_PWR_LED If this LED does not turn ON, it indicates that the USB enumeration of the kit did not happen with the host PC. This LED blinks continuously when the device is being programmed through the PSoC 5LP device. Note: This LED may glow with low intensity under the following condition: USB Power and Status Indicator The CY29412 supply is disconnected through jumper J1. This low-intensity LED glow may be misleading to the user on the status of the USB connection to the board. It is, therefore, recommended to avoid this condition during usage of the kit. LED2 POWER_LED This LED turns ON when the core of the CY29412 device is powered. Ensure that a jumper shunt is populated or not populated on J13 as per Table 4-2 for proper supply of the CY29412. Clock Device Power The intensity of the LED for 1.8 V is lower when compared to 2.5 V and 3.3 V. 4.3 Evaluating Different I/O Standards Using the CY3676 EVK The CY29412 device has one differential clock output pair (CLOCK P and CLOCK N). The onboard components of the CY3676 outputs can be configured to different settings for evaluating different clock standards. Figure 4-3 and Table 4-5 provide the on-board components related to CY29412 output clocks. Figure 4-3.
