TIMING CHARACTERISTICS
(VDDD = VDDA = +5V, VSSD = VSSA = -5V, unless otherwise noted.)
Note 1:
Accuracy and dynamic performance tests performed after calibration.
Note 2:
Tested with 50% duty cycle. Duty cycles from 25% to 75% at 1.7MHz are acceptable.
Note 3:
See
External Clock section.
Note 4:
Guaranteed by design, not tested.
Note 5:
Measured in shutdown mode with CLK and SCLK low.
