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.
