A series resistor, RS, may be required for AT strip cut crystals.

The internal feedback resistor, RF, is typically in the range of 2 to 10 MΩ.

Refer to Section 6. “Oscillator Configuration” (DS61112) in the “PIC32 Family Reference Manual” for help in determining the best

oscillator components.

PBCLK out is available on the OSC2 pin in certain clock modes.

USB PLL is available on PIC32MX2XX devices only.
