Fig.19 Synchronization of the cascade for the various PCF8576 drive modes.
Excessive capacitive coupling between SCL or CLK and SYNC may cause erroneous synchronization. If this proves to be a problem, the capacitance
of the SYNC line should be increased (e.g. by an external capacitor between SYNC and V
DD
). Degradation of the positive edge of the SYNC pulse may
be countered by an external pull-up resistor.
