9.1.2 Output Stage

Each output drives 1.8-V LVCMOS levels. Adaptive output buffers limit the rise/fall time of the output to within 1 ns to 5 ns with load capacitance between 10 pF and 50 pF. Fast slew rates introduce EMI into the system. Each output buffer limits EMI by keeping the rise/fall time above 1 ns. Slow rise/fall times can induce additive phase noise and duty cycle errors in the load device. The output buffer limits these errors by keeping the rise/fall time below 5 ns. In addition, the output stage dynamically alters impedance based on the instantaneous voltage level of the output. This dynamic change limits reflections keeping the output signal monotonic during transitions. Each output is active low when not requested to avoid false clocking of the load device.
