Definitions
All timing specifications in this section refer to 0 8V or 2 0V
on the rising or falling edges of the signals as illustrated in
Figures 1-8 through 1-14 unless specifically stated other-
wise
Maximum times assume capacitive loading of 50 pF
CLKIN crystal frequency is 40 96 MHz
Note CTTL is an internal signal and is used as a reference to explain the
timing of other signals See Figure 1-22
Signal valid active or inactive time after a rising edge of CTTL or MWCLK
