tOSCSU — T Start-up time1,2

1 The start-up time is dependent upon crystal characteristics, board leakage, etc. High ESR and

excessive capacitive loads can cause long start-up time.

2 Value captured when amplitude reaches 90% of XTAL

CC T XTAL load capacitance3

3 This value is determined by the crystal manufacturer and board design. For 4 MHz to 40 MHz crystals

specified for this oscillator, load capacitors should not exceed these limits.
