7 Timing Requirements and Switching Characteristics
7.1 Timing Test Conditions
All timing requirements and switching characteristics are valid over the recommended operating conditions
unless otherwise specified.
7.2 Interface Clock Specifications
7.2.1 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.
7.2.2 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.
7.3 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:
