Output clkout[3:1] clocks come from:
• Either the input system clock and alternate clock (xi_osc0 or xi_osc1)
• Or a CORE clock (from CORE output)
• Or a 192-MHz clock (from PER DPLL output).
External Reference Clock [3:0].

6.1 Input Clock Specifications
6.1.1 Input Clock Requirements
• The source of the internal system clock (SYS_CLK1) could be either:
– A CMOS clock that enters on the xi_osc0 ball (with xo_osc0 left unconnected on the CMOS clock
case).
– A crystal oscillator clock managed by xi_osc0 and xo_osc0.
• The source of the internal system clock (SYS_CLK2) could be either:
– A CMOS clock that enters on the xi_osc1 ball (with xo_osc1 left unconnected on the CMOS clock
case).
– A crystal oscillator clock managed by xi_osc1 and xo_osc1.
• The source of the internal system clock (SYS_32K) could be either:
– A CMOS clock that enters on the rtc_osc_xi_clkin32 ball and supports external LVCMOS clock
generators
– A crystal oscillator clock managed by rtc_osc_xi_clkin32 and rtc_osc_xo.
