Notes:
13. Tested one output at a time, output shorted for less than one second, less than 10% duty cycle.
14. To guarantee positive currents for all PECL voltages, an external pull-down resistor must be present.
15. Maximum ICC is measured with VDD = MAX, RFEN = LOW, and outputs unloaded. Typical IDD is measured with VDD = 5.0V, TA = 25°C, RFEN = LOW, and
outputs unloaded.
16. Tested initially and after any design or process changes that may affect these parameters, but not 100% tested.
