FUNCTIONAL DESCRIPTION
The PPG36F-series device is a 6-bit digitally programmable pulse
generator. The width, PWA, depends on the address code (A5-A0)
according to the following formula:
PWA = PW0 + TINC * A
where A is the address code, TINC is the incremental pulse width of the
device, and PW0 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 10ns, 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.
SERIES SPECIFICATIONS
• Programmed pulse width tolerance: 5% or 2ns,
whichever is greater
• Inherent width (PW0): 12ns typical
• Inherent delay (TTO): 3.5ns ± 2ns
• Operating temperature: 0° to 70° C
• Supply voltage VCC: 5VDC ± 5%
• Supply current: ICC = 60ma typical
