10. This parameter is measured as an average over 1
11.
This is required for the duty cycle on the REF clock out to be as specified. The device will operate reliably with input duty cycles up to 30/70 but the REF clock
duty cycle will not be within data sheet specifications.
12. All outputs loaded as per
Table 9
below.
13. Probes are placed on the pins and measurements are acquired at 1.5V for 3.3V signals (see test and measurement set-up section of this data sheet).
14. Measured between 0.2V
and 0.7V
.
15. This measurement is applicable with Spread ON or Spread OFF.
16. Measured at crossing point (Vx) or where subtraction of CLK
–
CLK# crosses 0V Measured from V
OL
= 0.175V to V
OH
= 0.525V.
17. Measured from V
= 0.175V to V
OH
= 0.525V.
18. Determined as a fraction of 2*(Trise
–
Tfall)/ (Trise+Tfall).
19. Test load is Rta = 33.2
, Rd = 49.9
.
Multiple Supplies:
The Voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
Inom refers to the expected current based on the configuration of the device.
All outputs loaded as per maximum capacitive load table.
Absolute value = ((Programmed CPU Iref)
×
(2)) + 10 mA.
