6.7.3 Clock PLL Considerations with External Clock Sources
If the internal oscillator is bypassed, to minimize the clock jitter a single clean power supply should power
both the DM6431 device and the external clock oscillator circuit. The minimum CLKIN rise and fall times
should also be observed. For the input clock timing requirements, see Section 6.7.4, Clock PLL Electrical
Data/Timing (Input and Output Clocks).
Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock
source must meet the device requirements in this data manual (see Section 5.3, Electrical Characteristics
Over Recommended Ranges of Supply Voltage and Operating Temperature and Section 6.7.4, Clock PLL
Electrical Data/Timing (Input and Output Clocks).
