CXL1517N/1518N Notes) 1) Linearity testing For A channel, set input bias to ABCN - 0.2V first, and then set it to ABCN and ABCN + 0.2V. Then input a sine wave of 100kHz and 100mVp-p, and compare the three output amplitudes. For B channel and C channel, set input bias to ABBL + 0.45V first, and then set it to ABBL + 0.25V and ABBL + 0.05V. Then input a sine wave of 100kHz and 100mVp-p, and compare the three output amplitudes. The maximum output amplitude for the respective A, B and C channels is taken as Sout max and the minimum output amplitude as Sout min. The linearity of the respective channels is defined as: Lin. = Sout max - Sout min x 200 [%] Sout max + Sout min 2) Calculation of insertion gain difference As the maximum insertion gain among A, B and C channels is taken as Gmax and the minimum as Gmin, the insertion gain difference between channels G as: G = | 1 - 10 - ( Gmax20 Gmin ) | x 100 [%] 3) Calculation of linearity difference Define B channel linearity as LB and C channel linearily as LC we obtain the difference LBC as: LBC = | LB - LC | [%] 4) Cross-talk calculation CRTa : The cross-talk value of A channel when B and C channels are input : The output value of A channel when A channel is input OUTA-a SW3-a, SW4-a, SW5, 6-b OUTA-bc : The output value of A channel when B and C channels are input (Cross-talk component) SW3-a, SW4-b, SW5, 6-a CRTa = OUTA-bc OUTA-a x 100 [%] Clock Waveform Timing (140) 210ns (52.5) 87.5ns 10ns 10ns 90% XDL1 50% 10% 90% 50% 10% 17.5ns 10ns (52.5) 87.5ns 10ns 90% XDL2 50% 10% 90% 50% 10% -5- The value in brackets is for CXL1517N.
