Timing requirements (VCC = 5 V±10 %, VSS = 0 V, Ta = –20 to 85 °C, f(XIN) = 40 MHz when the clock source select bit = “0”✽, unless
otherwise noted)
✽ The rise and fall time of input signal must be 100 ns or less respectively, unless otherwise noted.

✽: f(XIN) = 20 MHz when the clock source select bit = “1”
Notes 1: When the clock source select bit = “1”, tc’s minimum limit is 50 ns.
2: When the clock source select bit = “1”, set tw(H)/tc and tw(L)/tc ratios to 45 to 55 %.
