M52347SP

MITSUBISHI ICs (Monitor) M52347SP/FP SYNC SIGNAL PROCESSOR DESCRIPTION The M52347 automatically selects three types of synchronous signals containing separate sync (positive and negative polarities of 0.5 to 2.5 VP-P), composite sync (positive and negative polarities of 0.5 to 2.5 VP-P) and sync-on-video (sync negative polarity), and performs waveform shaping. The IC is optimum to synchronous signal processing for multi-scan type display monitor. H. STATE 1 V. STATE 2 CLAMP SW 3 20 CLAMP TIMING 19 Y. POL. 18 H. POL.
