(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.)
(4) To reduce EMI and reflections, depending on the trace length, approximately 22 Ω to 50 Ω damping resistors are recommend on the
following outputs placed near the DM355: YOUT(0-7),COUT(0-7), HSYNC,VSYNC,LCD_OE,FIELD,EXTCLK,VCLK. The trace lengths
should be minimized.
