Figure 4-2: Switch Line Locking
The ability to manually re-synchronize the flywheel is also important when
switching asynchronous sources or to implement other non-standardized video
switching functions.
The GS1559 also implements automatic switch line lock handling. By utilizing the
synchronous switch points defined by SMPTE RP168 for all major video standards
with the automatic video standards detect function, the device automatically
re-synchronizes the flywheel at the switch point.
This function will occur regardless of the setting of the FW_EN/DIS pin.
