PLL0 electrical characteristics Symbol Parameter Conditions1 Min Typ Max Unit fPLL0IN PLL0 input clock2, 3 — 14 — 44 MHz PLL0IN PLL0 input clock duty cycle2 — 40 — 60 % fPLL0VCO PLL0 VCO frequency — 600 — 1250 MHz fPLL0PHI0 PLL0 output clock PHI0 — 4.76 — 6254 MHz fPLL0PHI1 PLL0 output clock PHI1 — 20 — 156 MHz tPLL0LOCK PLL0 lock time — — — 100 µs PLL0LTJ PLL0 long term jitter fPLL0IN = 8 MHz (resonator)5 fPLL0PHI0 = 40 MHz, 1 μs ± 1 ns fPLL0PHI0 = 40 MHz, 13 μs ± 1 ns IPLL0 PLL0 consumption — — 5 mA 1. VDD_LV_PLL0 =1.25 V ± 5%, TJ = -40 / 150 °C unless otherwise specified. 2. PLL0IN clock retrieved directly from either IRCOSC or external XOSC clock. 3. fPLL0IN frequency must be scaled down using PLLDIG_PLL0DV[PREDIV] to ensure the reference clock to the PLL analog loop is in the range 8 MHz-20 MHz 4. The maximum clock outputs are limited by the design clock frequency requirements as per recommended operating conditions. 5. VDD_LV_PLL0 noise due to application in the range VDD_LV_PLL0 = 1.25 V±5%, with frequency below PLL bandwidth (40 KHz) will be filtered. Table 21. FMPLL1 electrical characteristics Symbol Parameter Conditions1 Min Typ Max Unit fPLL1IN PLL1 input clock2 — 38 — 78 MHz PLL1IN PLL1 input clock duty cycle2 — 35 — 65 % fPLL1VCO PLL1 VCO frequency — 600 — 1250 MHz fPLL1PHI0 PLL1 output clock PHI0 — 4.76 — 625 MHz tPLL1LOCK PLL1 lock time — — — 100 µs fPLL1MOD PLL1 modulation frequency — — — 250 kHz | δPLL1MOD| PLL1 modulation depth (when enabled) Center spread 0.25 — 2 % Down spread 0.5 — 4 % IPLL1 PLL1 consumption — — 6 mA 1. VDD_LV_PLL0 = 1.25 V ± 5%, TJ = -40 / 150°C unless otherwise specified. 2. PLL1IN clock retrieved directly from either internal PLL0 or external XOSC clock.
