22. Appendix E System Clocks¶
| Clocks | Description |
|---|---|
| XTAL16M | Crystal oscillator for the system clock (16MHz or 32MHz). Crystal Constraint should be up to +/-40ppm. |
| XTAL32K | Crystal oscillator for the low power clock. Crystal Constraint should be up to +/-500ppm. |
| RCX | XTAL_LP replacement (10.5 KHz). |
| RC16 | RC oscillator (~15.5MHz) for the initial CPU clocking until the XTAL is settled. |
| RC32K | RC oscillator (32KHz) for clocking the HW-FSM at power up. |
| PLL96 | A PLL which will increase the system clock to 96MHz. |
