6.9.4.1.2 MCU_OSC0 LVCMOS Digital Clock Source

Figure 6-20 shows the recommended oscillator connections when MCU_OSC0_XI is connected to a 1.8V LVCMOS square-wave digital clock source.

Note:
  1. A DC steady-state condition is not allowed on MCU_OSC0_XI when the oscillator is powered up. This is not allowed because MCU_OSC0_XI is internally AC coupled to a comparator that can enter an unknown state when DC is applied to the input. Therefore, application software must power down MCU_OSC0 any time MCU_OSC0_XI is not toggling between logic states.
     
  2. The LVCMOS clock signal sourcing the MCU_OSC0_XI input must have monotonic transitions. The clock source should be connected to MCU_OSC0_XI with a point-to-point connection, via a series termination resistor placed near the clock source. The series termination resistor value should match the clock source output impedance to the transmission line impedance. For example, the series termination resistor value needs to be 20 ohms if the clock source has an output impedance of 30 ohms and the PCB signal trace has a characteristic impedance of 50 ohms. This allows the reflection that returns from the far end of the un-terminated transmission line to be completely absorbed such that is does not introduce any non-monotonic events on the signal.
     
  3. The PCB trace length connecting the LVCMOS clock source to MCU_OSC0_XI should be minimized. This reduces capacitive loading and decreases probability of external noise sources coupling into the clock signal. Reduced capacitive loading improves rise/fall times of the clock signal which reduces the probability of jitter being introduced in the system.

(1) Most LVCMOS oscillator datasheets define their maximum Output Rise/Fall times with a capacitive load much larger than the actual load that will be applied by the combined PCB trace capacitance and MCU_OSC0_XI input capacitance. It should not be difficult to find a LVCMOS oscillator that meets this requirement. However, the system designer must confirm the LVCMOS oscillator selected will provide the appropriate rise/fall time to MCU_OSC0_XI input.
(2) Most LVCMOS oscillator datasheets define their max RMS Phase Jitter using a larger bandwidth integration range than required by this device. To get a more appropriate value, it may be necessary to contact the LVCMOS oscillator manufacture and ask them to provide a maximum RMS Phase Jitter using the same bandwidth integration range that has been defined for this parameter.
