Notes
1 Parameters are valid over the specified temperature and operating supply ranges. Typical values are 25C, VCC = 5V and typical
processing parameters.
2 All voltages are referenced to ground (GND). For testing, input signal levels are 0.4V and 2.4V with a transition time of 20ns
maximum. All time measurements are referenced at input voltages of 0.8V and 2.0V as appropriate. See NO TAG.
3 Measured operating with a 3.6864 MHz crystal and with all outputs open.
4 The minimum high time must be at least 1.5 times the X1/CLK period and the minimum low time must be at least equal to the X1/CLK
period if either channel’s Receiver is operating in external 1X clock mode.
