4.2 Board Details

4.2.1 Default Jumper Settings

The CY3677 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

Description

J1

Pin 1 and 2 are shorted

Power on CY29430.

J2

Pin 1 and 2 are shorted

VCXO input set to 0 V.

J5

Pin 1 and 2 are shorted

CY29430 output termination voltage set to 0 V through the 50-

Ω termination resistors.

J13

Pin 2 and 3 are shorted

3.3 V selected for CY29430.

J14

Pin 1 and 2 are shorted

FS1 set to VDD_DUT

(logic ‘1’).

J15

Pin 1 and 2 are shorted

FS0 set to VDD_DUT

(logic ‘1’).

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 5 V 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 during
functional programming and must be set to 2.5 V during eFuse programming. 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

CY3677

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 CY29430 Device

The USB interface provides a 5-V power supply. The PSoC 5LP converts the JEDEC profiles into an I

2

C-compatible format,

which is then loaded into the CY29430 clock device.

Note:

During functional programming, keep the power supply of the CY29430 device (hardware settings) the same as in the

ClockWizard 2.1 configuration (software settings).

Table 4-2

provides the supply settings for the CY29430. During eFuse

programming, set the power supply of the CY29430 to 2.5 V.

The

Example Projects

section provides the example projects (

.cpj

files) created in ClockWizard 2.1.
