Unit Notes IDD_sirc8M Supply current in 8 MHz mode — 25 35 μA fsirc Output frequency — 2 — MHz 1 — 8 — Δfsirc Total deviation of trimmed frequency over voltage and temperature • 0 to 105 °C • -40 to 0 °C — — — — ±3 ±4 %fsirc 2 Δfsirc_t Total deviation of trimmed frequency over temperature @VDD=3.3V — — ±3 %fsirc 2 Tsu_sirc Startup time — — 12.5 μs Jcyc_sirc Period jitter (RMS) • fsirc = 2 MHz • fsirc = 8 Mhz — — 350 100 — — ps 3 1. Selection of output frequency for Slow IRC between 2 MHz and 8 MHz is controlled by SCG_ SIRCCFG[RANGE]. 2. Maximum deviation occurs at cold temperature (-40 °C) and hot temperature (105 °C). 3. This specification was obtained using a NXP developed PCB. Jitter is dependent on the noise characteristics of each PCB and results will vary. 8.3.1.3 System PLL specifications Table 27.
