Frequency Dependency For Timing Specifications
t_CK is defined as 0.5t_CKI. The ADSP-2141L uses an input clock
with a frequency equal to half the instruction rate: a 20.0 MHz
input clock (which is equivalent to 50 ns) yields a 25 ns processor
cycle (equivalent to 40 MHz). t_CK values within the range of 0.5t_CKI
period should be substituted for all relevant timing parameters to
obtain the specification value.
Example: t_CKH = 0.5t_CK – 7 ns = 0.5 (25 ns) – 7 ns = 8 ns
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADSP-2141L features proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
