The chip contains a PLL that sources 5 (or 4) multisynth clocks, which in turn can be directed to any of the 10 (or 4) outputs through a divider. The internal structure of the clock generators can be found in [2]. +The Si5345 is similar to the Si5341 with the addition of fractional input +dividers and automatic input selection, as described in [3]. +The Si5342 and Si5344 are smaller versions of the Si5345, with 2 or 4 outputs. The driver can be used in "as is" mode, reading the current settings from the chip at boot, in case you have a (pre-)programmed device.
