1. Unless noted otherwise, all parameters use a GRP load of 4 GLBs, 20 PTXOR path, ORP and Y0 clock.
2. Refer to Timing Model in this data sheet for further details.
3. Standard 16-Bit loadable counter using GRP feedback.
4.
f
max (Toggle) may be less than 1/(
t
wh +
t
wl). This is to allow for a clock duty cycle of other than 50%.
5. Reference Switching Test Conditions section.
