NOTES: 10. SCLK can drive an output capacitive load up to 60 pF. The worst-case transition time between the 10% and
90% levels is less than 4 ns (typical 3 ns). RCLK and VCLK can drive output capacitive loads up to 15 pF,
with worst case transition times between 10% and 90% levels less than 4 ns (typical 3 ns).
11. This parameter applies when the split shift register transfer (SSRT) function is enabled. See Section 2.15
for details.
12. The SCLK and VCLK delay time to RCLK depends on the load that the signals drive. This parameter is
measured with an RCLK to VCLK ratio of 1:1, and VCLK = RCLK load of 15 pF and SCLK load of 60 pF.
13. Measured from the 90% point of the rising edge of DOTCLK to 50% of the full-scale transition.
14. Measured from the 50% point of the full-scale transition to the point at which the output has settled, within
±
1 LSB (settling time does not include clock and data feedthrough).
15. Measured between 10% and 90% of the full-scale transition.
