Notes to tables:
(1) These values are specified in Table 3 on page 758.
(2) See Application Note 78 (Understanding MAX 5000 & Classic Timing) in this data book for more information on Classic
timing parameters.
(3) The non-Turbo adder must be added to this parameter when the Turbo Bit option is off.
(4) Sample-tested only for an output change of 500 mV.
(5) The fMAX values represent the highest frequency for pipelined data.
(6) Measured with a device programmed as a 16-bit counter.
(7) Sample-tested only. This parameter is a guideline based on extensive device characterization. This parameter
applies for both global and array clocking.
