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, 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. When the MX12 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 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 kΩ resistor should be used.)
