SI57X-EVB Summary of contents
Page 1
... 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 2 Si598/599 any frequency I C programmable XO/ VCXOs. Software is supplied for evaluation of the Si57x/598/599 device. All Si570 and Si598 XOs are pin and register compatible ...

... 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 power supply from the USB connection to the terminal block at J18, make these changes: Remove R7. ...

... 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. Reference ...

... 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. ...
