LA7357

Ordering number : EN5654 Monolithic Linear IC LA7357 PAL/SECAM Discrimination Circuit for VHS VCRs Overview The LA7357 can be used as a PAL/SECAM discrimination IC. Since no ceramic resonator or tank circuit is required, only a small number of external components are used, and the LA7357 can contribute to reduced mounting areas and lower system costs.
