EVB
Driver (USBXpress)
2. Verify Si57x Motherboard jumper settings are correct. (The default installation assumes a 3.3V OE active high DUT. Otherwise refer to Table 3.) 3. Connect the USB cable from the EVB to the host PC. 4. Install the EVB Driver on the host PC. 5. Install the Programmable Oscillator Software from the CD or zip file. 6. Launch the Programmable Oscillator Software by clicking StartProgramsSilicon LaboratoriesProgrammable Oscillator Software and selecting one of the applications.
Note: The above instructions assume an assembled daughterboard is available. If it is not available, install the Si57x/598/599 DUT and place proper output components on the daughterboard as described in "1.9. Si57x Daughterboard" on page 9.
The Si57x motherboard is normally operated together with a Si57x daughterboard populated with an Si570/ 571/598/599. This combination is referred to as the Si57x-EVB assembly that is also used to evaluate the Si598/599 any frequency I2C programmable XO/ VCXOs. Software is supplied for evaluation of the Si57x/598/599 device. All Si570 and Si598 XOs are pin and register compatible. The Si571 and Si599 VCXOs are pin and register compatible. The Si57x-EVB supports all configurations of these devices. The software components run on a USB-equipped PC and are described in detail in "4. Software Installation" on page 12.
Note: Si57x/598/599 samples must be ordered separately from the Si57x-EVB.

1. Functional Description
The Si57x-EVB is the evaluation board assembly for the Si57x/598/599 any frequency I2C programmable XO/ VCO. This evaluation board assembly provides access to all signals for programming and operating the device. The Si57x-EVB assembly motherboard and daughterboard schematics, bills of material, and PCB layouts are appended as sections 5, 6 and 7, respectively. Reference designators below refer to the Si57x-EVB motherboard unless otherwise noted. The Si57x-EVB is oriented with the daughterboard at the bottom in the directions below.
1.1. Motherboard-Daughterboard Connection
The Si57x-EVB motherboard connects to the Si57x daughterboard at connectors J13-J14. Each of these is a 2x20 pin, impedance controlled connector. The connectors are keyed so there is only one proper way to install the board. Orient the boards on installation so that the silkscreen triangle on the daughterboard matches the silkscreen on the motherboard.
1.2. Power Supply
The Si57x-EVB is pre-configured to accept 5 V from the USB connector at J15. To change the board's 5 V power supply from the USB connection to the terminal block at J18, make these changes:
Remove R7. Populate R8.
Note: If both R7 and R8 are installed, do not simultaneously connect to both the USB connector at J15 and to a separate 5 V supply at J18. Otherwise, power supply contention may occur.
Typical supply current draw for the Si57x-EVB assembly (motherboard + daughterboard) is approximately 230 mA. See the device data sheet for device power consumption specifications. The evaluation daughter board are designed to operate at any of the following nominal voltages: 1.8, 2.5, or 3.3 V. The Si57x-EVB has an on-board voltage regulator which supplies any of these voltages. The Si57x-EVB voltage regulator is controlled via jumpers. By default, a jumper is installed, selecting 3.3 V for the Si57x/598/599. Alternatively, VREG may be set to 1.8 or 2.5 V per Table 1.
Table 1. VREG Jumpers

1.3. Reset Circuit
The Si57x-EVB MCU may be reset by pressing momentary pushbutton SW1. It may also be held in reset by installing a jumper at J7. MCU outputs are open drain and are tri-stated during reset. They remain tri-stated unless otherwise directed under program control. There is no hardware reset for the Si57x/598/599 itself. The Si57x/598/599 is reset only on power-up or through software. Pressing the Si57x-EVB motherboard pushbutton SW1 in an attempt to reset the Si57x/598/599 may result in unexpected behavior.
1.4. USB
A 4-pin USB receptacle is provided at location J15. The Si57x-EVB, via the MAC’s USB Function Controller, is compatible with USB Specification 2.0. When the USB link is in use the MCU drives LED D7.
1.5. MCU
The MCU, Silicon Laboratories P/N C8051F320, provides the following functions: Supports I2C communication to the DUT on behalf of the host PC per the Si57x-EVB software Drives a number of status indicator LEDs (see Table 2) Supplies 3.3 V to peripheral ICs on the motherboard but not to the DUT The MCU comes pre-loaded with firmware. While there is a provision for in-circuit programming at connector J12 located on the back, this should not be necessary. The host PC operates the Si57x/598/599 software and communicates to the Si57x/598/599 through the MCU via USB connector J15. When the USB link is in use, LED D7 should be illuminated.
As mentioned earlier, the MCU may be reset by pressing momentary pushbutton (SW1) or held in reset by installing a jumper at J7. 1.5.1. Status Signals There are seven LEDs on the Si57x-EVB that report visual status as listed in Table 2 and as highlighted in Figure 2. Upon power up, D1–D2 and only one of D3–D5 should be illuminated. D6 and D7 are only illuminated when in use.

1.5.2. Jumpers There are eight jumper locations on the Si57x-EVB as listed in Table 3. (The reference designations J4-J5 and J16-17 are assigned to other connector types.) The default or pre-loaded jumpers are shown in Figure 3.

1.6. Si57x/598/599 I2C Communication Configuration
The Si57x/598/599 supports I2C serial communication through the SDA and SCL pins. All Si570 and Si598 XOs are pin and register compatible, and all Si571 and Si599 VCXOs are pin and register compatible. The device can be operated as an I2C slave only. The MCU supports I2C communication to the DUT. The Si57x-EVB must be configured by jumpers as described below to select the intended I2C communications path depending on the DUT's nominal supply voltage. For I2C communication with the Si57x/598/599 DUT = 2.5 or 3.3 V nominal, there must be jumpers installed at J1, J2, and J11 pin 2. This defeats and bypasses the installed bidirectional voltage level translator at U3. (For I2C communication with the Si57x/598/599 DUT at 1.8 V nominal supply, please consult the factory.)
1.7. Si57x/598/599 Digital Control Signals
There is one normally static digital input control signal that routes to the Si57x/598/599: Output Enable or OE. By default, the OE signal is pulled HIGH on the Si57x-EVB and may be pulled low by installing a jumper at J9. To support OE active LOW control, make the following changes to the Si57x motherboard: Install R9. Remove R14. You can then selectively disable the OE active LOW by installing a jumper at J3. See Figure 4 for the location of these components.
1.8. Si57x/598/599 Voltage Control Signal
An external voltage control signal may be applied to the control voltage modulation input at SMA connector J17, silkscreen designation VC_MOD). This voltage supplies the control voltage or voltage modulation input to an Si571 when installed on the DB. No jumper changes are required to support the Si570/598 versus the Si571/599. Pin 1 on the Si571 is the VC pin and is a N/C for the Si570.

1.9. Si57x Daughterboard
The Si57x daughterboard can accommodate either Si570/571/598/599 devices and supports all output formats. All Si570 and Si598 XOs are pin and register compatible, and all Si571 and Si599 VCXOs are pin and register compatible. Typically, the boards are shipped without the sample device or any output components. Table 4 lists suggested output loading options for different output formats and coupling configurations.

2. Clock I/O
There are no input clock signals that are routed to and from the DUT via the motherboard. The Si57x daughterboard output clocks are directly routed from the Si57x daughterboard to SMA connectors J4 and J5. These connectors are designated CLKP and CLKN, respectively. Each of these output clocks needs to be terminated into 50 single-ended, 100 differential. Any ac coupling caps or near end LVPECL bias resistors have to be provided for on the Si57x daughterboard.
