LISY300AL

10/13

The LISY300AL IC includes a PLL (phase locked loop) circuit to synchronize driving and

sensing interfaces. Capacitors and resistors must be added at the FILTVDD and VCONT

pads (as shown in Figure 3) to implement a second-order low-pass filter. Table 6

summarizes the PLL low-pass filter components’ values.
