TERMINAL

TYPE(1)

OTHER(2)(3)

DESCRIPTION

NAME

NO.

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

VDD

MXO2 is not used and powered down, the MXO2 signal should be left as a No

Connect.

The provides Real Time Output (RTO) interface.

(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.)

The provides Pulse Width Modulator (PWM) interface.
