66 / 103 page  Electrical characteristics SPC560P34L1, SPC560P34L3, SPC560P40L1, SPC560P40L3 66/103 Doc ID 16100 Rev 7 3.12 FMPLL electrical characteristics Table 26. Main oscillator output electrical characteristics (3.3 V, NVUSRO[PAD3V5V] = 1) Symbol C Parameter Conditions Value Unit Min Max fOSC SR — Oscillator frequency 4 40 MHz gm — P Transconductance 4 20 mA/V VOSC — T Oscillation amplitude on XTAL pin 1 — V tOSCSU — T Start-up time (1),(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 8— ms CL CC T XTAL load capacitance(3) 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. 4MHz 5 30 pf T8 MHz 5 26 T12 MHz 5 23 T16 MHz 5 19 T20 MHz 5 16 T40 MHz 5 8 Table 27.
