4. Noise on the VDD supply with frequency content below 40 kHz and above 50 MHz is filtered by the PLL. Noise on the VDD

supply with frequency content in the range of 40 kHz – 50 MHz must be filtered externally to the device.

1. PLL1IN clock retrieved directly from either internal PLL0 or external XOSC clock. Input characteristics are granted when

using internal PLL0 or external oscillator in functional mode.

2. 264 MHz applies to the MPC5777C part number with 264 MHz max operating frequency. 300 MHz applies to the version

with 300 MHz operating frequency

3. Noise on the VDD supply with frequency content below 40 kHz and above 50 MHz is filtered by the PLL. Noise on the VDD

supply with frequency content in the range of 40 kHz – 50 MHz must be filtered externally to the device.
