10.7 Crystal Oscillator Parameters
Freescale Semiconductor
Preliminary
1. An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work correctly.
2. ZCLK may not exceed 60MHz. For additional information on ZCLK and (f
3. This is the minimum time required after the PLL set up is changed to ensure reliable operation.
