Notes
5. I
CCI
measurement is performed with Bank1 and FB Bank configured to run at maximum frequency (f
NOM
= 100 MHz for CY7B9930V, f
NOM
= 200 MHz for CY7B9940V),
and all other clock output banks to run at half the maximum frequency. FS and OUTPUT_MODE are asserted to the HIGH state.
6. This is dependent upon frequency and number of outputs of a bank being loaded. The value indicates maximum I
CCN
at maximum frequency and maximum load of
25 pF terminated to 50Ω at V
CC
/2.
7. This is for non-three level inputs.
8. Assumes 25 pF Max. Load Capacitance up to 185 Mhz. At 200 MHz the max load is 10 pF.
9. Both outputs of pair must be terminated, even if only one is being used.
10. Each package must be properly decoupled.
11. AC parameters are measured at 1.5V, unless otherwise indicated.
12. Test Load C
L
= 25 pF, terminated to V
CC
/2 with 50Ω.
13. SKEW is defined as the time between the earliest and the latest output transition among all outputs for which the same phase delay has been selected when all outputs
are loaded with 25 pF and properly terminated up to 185 MHz. At 200 MHz the max load is 10 pF.
14. Guaranteed by statistical correlation. Tested initially and after any design or process changes that may affect these parameters.
15. Tested initially and after any design or process changes that may affect these parameters.
16. Rise and fall times are measured between 2.0V and 0.8V.
