The M52036SP is a semiconductor integrated circuit for the automatic selection and rectification of sync waveforms. The IC operates with synchronizing signals in three forms, that is, separate sync(positive or negative polarity, 1 to 5 Vp-p), composite sync (positive or negative polarity, 1 to 5 Vp-p), and synchronous video (negative sync). This IC is optimal for processing sync signals for multi-scan-type displays.
