MITSUMI No-adjustment Sync Separator + Sync Detector MM1067 No-adjustment Sync Separator + Sync Detector Monolithic IC MM1067 Outline This IC is a no-adjustment sync separator + sync detector designed for use in VCR, TV and other video equipment. Features 1. Sync separator with AFC (ceramic resonator means no adjustment required) 2. Composite and sync output pins 3. Sync detection circuit (used for blue-back switching or tuner automatic channel selection, etc.) 4. Power supply voltage VCC=5V 5. Ceramic resonator can be selected for use in either PAL or NTSC Package SOP-16A (MM1067XF) DIP-16A (MM1067XD) Applications 1. TV 2. VCR 3.
