DSP1628 Digital Signal Processor
10 Timing Characteristics for 2.7 V Operation
10.1 DSP Clock Generation
* See Table 62 for input clock electrical requirements.
† Free-running clock.
‡ Wait-stated clock (see Table 38).
§ W = number of wait-states.
Table 66. Timing Requirements for Input Clock
* Device speeds greater than 50 MIPS do not support 1X operation. Use the PLL.
† Device is fully static, t1 is tested at 100 ns for 1X input clock option, and memory hold time is tested at 0.1 s.
Table 67. Timing Characteristics for Input Clock and Output Clock
* T = internal clock period, set by CKI or by CKI and the PLL parameters.
