Product Details
__
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 processing, to allow efficient utilization of the CPU.
