FUNCTIONAL DESCRIPTION
The PPG33F-series device is a 3-bit digitally programmable pulse
generator. The width, PW
A
, depends on the address code (A2-A0)
according to the following formula:
PW
A
= PW
0
+ T
INC
* A
where A is the address code, T
INC
is the incremental pulse width of the
device, and PW
0
is the inherent pulse width of the device. The
incremental width is specified by the dash number of the device and can range from 0.5ns through 50ns,
inclusively. RESET is held LOW during normal operation. When it is brought HIGH, OUT and OUT/ are
forced into LOW and HIGH states, respectively, and the unit is ready for the next trigger input. The
address is not latched and must remain asserted while the output pulse is active.
