Notes:
1.The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state)
(reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMDKHDX
symbolizes management data timing (MD) for the time tMDC from clock reference (K) high (H) until data outputs (D) are
invalid (X) or data hold time. Also, tMDDVKH symbolizes management data timing (MD) with respect to the time data
input signals (D) reach the valid state (V) relative to the tMDC clock reference (K) going to the high (H) state or setup
time. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
2.This parameter is dependent on the CCB clock speed (that is, for a CCB clock of 267 MHz, the maximum frequency is
8.3 MHz and the minimum frequency is 1.2 MHz; for a CCB clock of 333 MHz, the maximum frequency is 10.4 MHz
and the minimum frequency is 1.5 MHz).
3.This parameter is dependent on the CCB clock speed (that is, for a CCB clock of 267 MHz, the delay is 60 ns and for a
CCB clock of 333 MHz, the delay is 48 ns).
4.Guaranteed by design.
