Overview
MITSUMI Sync Detector MM1069 Sync Detector Monolithic IC MM1069 Outline This IC is a sync detection circuit for obtaining the best reception state on VCR and TV channel selection systems.
A system with high detection precision and no adjustment required can be configured due to the PLL format using a ceramic resonator.
It can also be used in OSD circuits for blue-back switching and the like.
Features 1.
Can be used in VCR and TV channel selection systems, and also for blue-back, etc.
2.
High precision due to use of PPL format 3.
Ceramic resonator means no adjustment required 4.
Ceramic resonator can be selected for use in either PAL or NTSC 5.
