Product data sheet Rev. 09 — 9 July 2009 36 of 56 NXP Semiconductors PCF8576C Universal LCD driver for low multiplex rates The SYNC line is provided to maintain the correct synchronization between all cascaded PCF8576Cs. This synchronization is guaranteed after the power-on reset. The only time that SYNC is likely to be needed is if synchronization is accidentally lost (e.g. by noise in adverse electrical environments; or by the defining a multiplex mode when PCF8576Cs with differing SA0 levels are cascaded). SYNC is organized as an input/output pin; the output selection being realized as an open-drain driver with an internal pull-up resistor. A PCF8576C asserts the SYNC line and monitors the SYNC line at all other times. If synchronization in the cascade is lost, it is restored by the first PCF8576C to assert SYNC. The timing relationship between the backplane waveforms and the SYNC signal for the various drive modes of the PCF8576C are shown in Figure 30. For single plane wiring of packaged PCF8576Cs and chip-on-glass cascading, see Figure 31. . Fig 29.
