CL1 external crystal load capacitor | See equation in Section 10.1.2 notes | pF |
CL2 external crystal load capacitor | See equation in Section 10.1.2 notes | pF |
PCB layout | A ground isolation ring around the crystal is recommended |
If an external oscillator is used, then the oscillator output must drive the PLL_REFCLK_I pin on the DLPC34xx controller, and the PLL_REFCLK_O pin must be left unconnected.
