Notes:

1. Si5xx samples must be ordered separately from the Si5xx-PROG-EVB.

2. Board must be modified to be consistent with the ordered part. See "3.10. Output Terminations" on page 8.

3. Si514-PROG-EVB comes with an Si514 preinstalled.

1.1. Quick Start

1. Install an Si514, Si570, Si571, Si598, or Si599 device on the board (Si514-PROG-EVB comes with an Si514
preinstalled; the Si570-PROG-EVB also comes with an Si570 installed).

2. Verify that the jumper settings are correct.

3. Connect the USB cable from the EVB to the host PC.

4. Install the Programmable Oscillator Software and driver.

5. Launch the Programmable Oscillator Software by clicking Start  Programs  Silicon Laboratories 
Programmable Oscillator Software. Click on one of the shortcuts in the group.

The Si5xx-PROG-EVB is the evaluation board assembly for the Si514/570/571/598/599 Any-Frequency I2C
Programmable XO/VCO. This evaluation board assembly provides access to all signals for programming and
operating the device. The Si5xx-PROG-EVB schematics, bill of materials, and PCB layouts are included as
sections 6, 7, and 8, respectively. Figure 2 provides a block diagram for the board.

3.1. Power Supply

The Si5xx-PROG-EVB is pre-configured to accept 5 V from the USB connector at J2. The DUT is powered from
the VDD regulator by default, but could be changed to an external supply introduced through J1. To do this, simply
move jumper J11 from pins 2-3 to 1-2 and apply power to J1. (Ensure the voltage range of the DUT is obeyed, and
it is also good practice to set a current limit on the power supply).

It is also possible for the microcontroller (U9) to adjus t the VDD regulator through the software. The microcontroller
has pull-downs configured at P0.0 and P0.1 that grounds R18 and R19, respectively, adjusting VDD_DUT to 1.8,

2.5, or 3.3 V. It is also possible to install jumpers in J5 to manually force a VDD_DUT voltage. Table 2 illustrates the

settings of J5:

1–2 3.3 V
3–4 2.5 V

3.2. Reset Circuit

The Si5xx-PROG-EVB MCU may be reset by momentarily pressing pushbutton SW1.

3.3. USB

A 4-pin USB receptacle is provided at location J2. The Si5xx-PROG-EVB is compatible with USB Specification 2.0.
When the USB link is in use, the MCU drives LED D4.

3.4. MCU

The Silicon Laboratories MCU, P/N C8051F342, provides the following functions:

 Supports I
 Drives a number of status indicator LEDs (see Table 3)
 Supplies 3.3 V to peripheral ICs on the motherboard but not to the DUT
 Controls DUT power (see Section “3.1. Power Supply” )
 Auto-detects the part type (e.g., Si51x/Si57x/Si59x)

There is a provision for in-circuit programming at connector J4. This provision should not be needed in normal
operation. The host PC operates the software and communicates to the Si5xx-PROG-EVB through the MCU via
USB connector J2. When the USB link is in use, LED D4 should flash. The MCU may be reset by momentarily
pressing pushbutton (SW1).
