The analog outputs on X9 through X12 are (12-bit) filtered PWM signals, therefore a PWM frequency in
the range of 30-40 KHz and a PWM deadtime of zero are suggested for a good quality analog output
signal (minimized ripple). A fully populated Brick can have one of three gates generating the clocks:
Servo IC 0 (I7000’s)
Servo IC 1 (I7100’s)
MACRO IC 0 (I6800’s)
I19 specifies which gate is the clock source master. I19 is equal to 7007 by default indicating that Servo
IC 0 is the master gate. However, the analog outputs on X9 through X12 are generated out of Servo IC1.
The relationship between the PWM clock frequency of Servo IC 1 (recipient) and the master gate
(generator), typically Servo IC 0, should always be respected in such a way that:
Where n is an integer
Examples:
With Servo IC 0 sourcing the clock at its default settings (4.5 KHz PWM), the following are suggested
Servo IC 1 clock settings which would provide a good analog output signal:
