Clocks Terminal Functions TERMINAL TYPE(1) OTHER(2)(3) DESCRIPTION NAME NO. CLKOUT1 CLKOUT: Output Clock 1 D12 I/O/Z VDD / GIO018 GIO: GIO[018] CLKOUT2 CLKOUT: Output Clock 2 A11 I/O/Z VDD / GIO017 GIO: GIO[017] CLKOUT3 CLKOUT: Output Clock 3 C11 I/O/Z VDD / GIO016 GIO: GIO[016] MXI1 A9 I VDD Crystal input for system oscillator (24 MHz or 36 MHz) Output for system oscillator (24 MHz or 36 MHz). When the MX02 is not used, MXO1 B9 O VDD the MX02 signal can be left open. Crystal input for video oscillator (27 MHz) Optional, use only if 27MHz derived from MXI1 and PLL does not provide sufficient performance for Video DAC. MXI2 R1 I VDD When the MXI2 is not used and powered down, the MXI2 signal should be left as a No Connect Output for video oscillator (27 MHz) Optional, use only if 27MHz derived from MXI1 and PLL does not provide sufficient performance for Video DAC When the MXO2 T1 O VDD MXO2 is not used and powered down, the MXO2 signal should be left as a No Connect. (1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal. (2) Specifies the operating I/O supply voltage for each signal. See Section 5.3, Power Supplies for more detail. (3) PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 k Ω resistor should be used.)
