Example Configurations for the MPC93R52
TIMING SOLUTIONS
fref = 100 MHz
MPC93R52 default configuration (feedback of QB0 = 100
MHz). All control pins are left open.
MPC93R52 configuration to multiply the reference frequen-
cy by 3, 3 2 and 1. PLL feedback of QA4 = 33.3 MHz.

Figure 4. MPC93R52 Zero Delay Buffer Configuration
fref = 62.5 MHz
fref = 33.3 MHz
MPC93R52 zero–delay (feedback of QB0 = 62.5 MHz).
All control pins are left open except FSELC = 1. All out-
puts are locked in frequency and phase to the input clock.
MPC93R52 zero–delay (feedback of QB0 = 33.3 MHz).
Equivalent to Table 2 except F_RANGE = 1 enabling a
lower input and output clock frequency.
