AC characteristics apply for parallel output termination of 50 to V TT .
PLL mode requires PLL_EN=0 to enable the PLL and zero-delay operation.
The PLL may be unstable with a divide by 2 feedback ratio.
In PLL bypass mode, the MPC93R52 divides the input reference clock.
The input frequency f ref on CCLK must match the VCO frequency range divided by the feedback divider ratio FB: f ref = f VCO
See Table 9 and Table 10 for output divider configurations.
The MPC93R52 will operate with input rise and fall times up to 3.0 ns, but the AC characteristics, specifically t ( ) , can only be guaranteed if
tr/tf are within the specified range.
See application section for part-to-part skew calculation.
See application section for a jitter calculation for other confidence factors than 1 s .
