Notes
Each parameter is valid within the specified ranges of temperatures and supply voltages unless otherwise
noted.
Each voltage value is based on the GND (V
SS
=
0.0 V) level. The timing measurement reference point is 1.5
V, the input level is 0.4 to 2.4 V, and the input rise time and fall time are 2 ns or less.
Do not leave more than one output pins short-circuited for 1 second or more.
The external output load capacitance is 30 pF.
The specifications of pins other than those pins designated as asynchronous inputs and than the RDYOUT#
pin in external ready mode are determined by the rising edge of the external clock (CLKIN).
These specifications are subject to change for improvement.
The reset period requires at least 4 CLKIN cycles. The PLL oscillation stabilization delay time requires at least
4000 clock (CLKIN) pulses. For 40 MHz (25 ns) clock input, for example, the reset signal must therefore be
negated 100
μ
s later.
An AC characteristic of pins and internal maximum operation frequency is separately defined.
The maximum operation frequency of an external bus is 40MHz though the maximum internal operation
frequency are 90 MHz or 100 MHz (CLKIN Min.=25ns).Therefore,when an external bus is used with 40MHz,
an internal frequency is 80 MHz
