5.9.1

Timing Parameters and Information

The timing parameter symbols used in the timing requirement and switching characteristic tables are

created in accordance with JEDEC Standard 100. To shorten the symbols, some of pin names and other

related terminologies have been abbreviated as follows:

Interface Clock Specifications

5.9.2.1

Interface Clock Terminology

The interface clock is used at the system level to sequence the data and/or to control transfers accordingly

with the interface protocol.

5.9.2.2

Interface Clock Frequency

The two interface clock characteristics are:

•

The maximum clock frequency

•

The maximum operating frequency

The interface clock frequency documented in this document is the maximum clock frequency, which

corresponds to the maximum frequency programmable on this output clock. This frequency defines the

maximum limit supported by the Device IC and does not take into account any system consideration

(PCB, peripherals).

The system designer will have to consider these system considerations and the Device IC timing

characteristics as well to define properly the maximum operating frequency that corresponds to the

maximum frequency supported to transfer the data on this interface.
