NOTE 7:
This voltage specification is included for interface to HC logic. However, note that all of the other timing parameters defined in this data
sheet are specified for TTL logic levels and will differ for HC logic levels.

EXTERNAL CLOCK REQUIREMENTS
The TMS320C14/E14/P14 use an external frequency source for a clock. This source is applied to the CLKIN
pin, and must conform to the specifications in the table below.
