Effective Capacitance Calculation
The capacitance of the NUF2900MN can be determined a number of ways. When evaluated using low frequency, low current capacitance measurement equipment CLINE (line capacitance), it is determined to be approximately 33 pF. When used in systems that have signal rise and fall times of 1 ns or less CEFFECTIVE (effective capacitance), it is closer to 10.4 pF. If the rise and fall times of a signal is determined by the capacitance of the NUF2900MN, then an "effective" capacitance can be calculated using the following function based on a simple "RC" combination.

* 1.08ns CEffective + 50 ln(1 * 0.88)
NUF2900MN
RSource + CEffective VSource RTermination VIN VOUT
The rise time "t" is approximately 1.08 ns with VOUT 88% of VIN where the network impedance is 50 W. When solving for CEFFECTIVE, the capacitance is found to be 10.4 pF.
If the data signal source has a rise and fall time slower than 1 ns, the NUF2900MN will have a filtered output with a similar rise and fall time. CEFFECTIVE will scale accordingly as rise/fall times increase until it reaches CLINE.
