一、增加 LP 功能松下 NV G33录像机采用μPD6160CA(IC_(2101))作为数字伺服电路。此集成块设计功能完善,内部不仅设置 LP 速度模式,还具有根据重放 CTL 信号来识别放像速度(LP/SP)的检测电路。在重放 LP 带时,IC_(2101)(μPD6106CA)第⑧脚输出高电平;在重放 SP 带时,IC_(2101)⑧脚输出低电平。改制时可以利用这一高低电平的变化,控制该机系统控制微处理器 IC_(6001)
First, increase the LP function Panasonic NV G33 VTR with μPD6160CA (IC_ (2101)) as a digital servo circuit. The integrated block design is fully functional. Not only the LP speed mode is set internally, but also the detection circuit that recognizes the playback speed (LP / SP) based on the playback CTL signal. When replaying the LP band, pin ⑧ of IC_ (2101) (μPD6106CA) outputs high level; when SP band is replayed, IC_ (2101) ⑧ pin outputs low level. When restructuring can take advantage of the level of change, control the aircraft system control microprocessor IC_ (6001)
