SDA 9205-2
The external clamping capacitance is loaded by on chip current sources (typ. 200 µA) during
clamping. So the loading time depends on the values of C_{ext cl}.
The loading time for a complete loading cycle is 1200 CLK pulses typical (44 µs with 27 MHz CLK
and C_{ext cl} = 10 nF) as shown in figure 1.
C_{ext cl} = 10 nF, R_S = 50 Ω
