SWITCHING CHARACTERISTICS over COMMERCIAL and INDUSTRIAL operating ranges
Software Halt Cycle (20 MHz and 25 MHz)
Notes:
All timing parameters are measured at 1.5 V with 50 pF loading on CLKOUTA, unless otherwise noted. All output test conditions
are with C
a Testing is performed with equal loading on referenced pins.
b This parameter applies to the DEN signal.
SWITCHING CHARACTERISTICS over COMMERCIAL operating ranges
Software Halt Cycle (33 MHz and 40 MHz)
Notes:
All timing parameters are measured at 1.5 V with 50 pF loading on CLKOUTA, unless otherwise noted. All output test conditions
are with C
a Testing is performed with equal loading on referenced pins.
b This parameter applies to the DEN signal.
