• Each parameter is valid within the specified ranges of temperatures and supply voltages unless otherwise
• Each voltage value is based on the GND (V
• 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#
• 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
output

V, the input level is 0.4 to 2.4 V, and the input rise time and fall time are 2 ns or less.
pin in external ready mode are determined by the rising edge of the external clock (CLKIN).
4000 clock (CLKIN) pulses. For 40-MHz (25 ns) clock input, for example, the reset signal must therefore be
negated 100 s later.
