Video ICs System control servo BU38603 / BU38703 / BU38803 The BU38603, BU38703 and BU38803 are servo controller ICs for VCRs. They contain a high-speed, 8-bit CPU and perform the processing required for the drum, capstan, FV and PV completely in software, allowing a large reduction in the number of external components required. They also contain high-performance linear amplifiers, eliminating the need for interface ICs. Specialized hardware is included for items that require high-speed process.
