For the application which does not require the accurate oscillation, use K rank (±10%) with SL characteristics.
Table 3. Crystal Oscillation Guaranteed Constant (sub-clock)
(Notes) • Since the circuit pattern affects the oscillation frequency, place the oscillation-related parts as close to the oscillation pins
as possible with the shortest possible pattern length.
• If you use other oscillators herein, we provide no guarantee for the characteristics.
• Adjust the voltage of monitor point in Figure 11 to 1/2VDD±10% by the LC oscillation constant 'L' or 'C' to lock the PLL
circuit.
