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. 2 Rev. 0.3 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. Rev. 0.3 3 2.

Functional Description 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.

Si5xx-PROG-EVB Functional Block Diagram Rev. 0.3 5 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 adjust 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: Table 2. J5 settings for VDD_DUT Jumper VDD_DUT Open 1.8 V 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 I2C communication to the DUT on behalf of the host PC per the Programmable Oscillator Software 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). 6 Rev. 0.3 3.5. Status Signals There are four LEDs on the Si5xxPROG-EVB that report visual status as listed in Table 3 and shown in Figure 1b. Upon powerup, D1 should be illuminated. Table 3.

Jumpers There are seven jumper locations on the Si5xx-PROG-EVB as listed in Table 4. The default or pre-loaded jumpers are shown in Figure 1a. Table 4.

External I2C Communication It is possible to use an external I2C controller to communicate with the DUT. To do this, remove the jumpers installed in J20 and connect the external I2C harness to J20. Grounded pins (1-2, 7-8) are there for grounding the harness. Pins 4 and 6 can be driven as SCL and SDA, respectively. 3.8. Si5xx-PROG-EVB Digital Control Signal One normally static digital input control signal routes to the Si5xx: Output Enable or OE. By default, the OE signal is pulled HIGH on the Si5xx-PROG-EVB and may be pulled low by installing a jumper at J16. 3.9. Si5xx-PROG-EVB Voltage Control Signal An external voltage control signal may be applied to the control voltage modulation input at the J12 header (VCO_IN). This voltage supplies the control voltage or voltage modulation input to the DUT. J13 should be installed in the 2-3 position. 3.10. Output Terminations The Si5xx-PROG-EVB can support four different output formats: CMOS, LVPECL, LVDS, and HCSL. There are output resistors that are needed to accompany each format. Table 5 shows which resistors are needed for each output: Table 5.
