1 to 710 MHz. The clock frequency range and loop bandwidth are selectable from a simple look-up table. The Si5317-EVB has a differential clock input that is AC terminated to 50 and then AC-coupled to the Si5317. The two clock outputs are AC-coupled. The XA-XB reference is usually a 114.285 MHz crystal; but there are provisions for an external XA-XB reference (either differential or single-ended).

XA-XB pins. To that end, the EVB is configured with a 114.285 MHz third overtone crystal connected between pins 6 and 7 of the Si5317. However, the Si5317-EVB is also capable of using an external XA- XB reference oscillator, either differential or single-ended. For details concerning the allowed XA-XB reference frequencies and their RATE settings, see the Si5317 data sheet.

Si5317-EVB 2.3. Output Clock The clock outputs are AC-coupled and are available on SMAs J5, J7, J9 and J11. For LVCMOS outputs, it might be desirable to replace the AC coupling capacitors (C9,C14,C17, and C20) with 0 resistors. Also, if greater drive strength is desired for an LVCMOS output, R6 and R10 can be installed.
