HCTL-2021中文資料(HCTL2017 / HCTL2021) Quadrature Decoder/Counter Interface ICs數(shù)據(jù)手冊Broadcom規(guī)格書

描述 Description

The HCTL-2021/2017 is CMOS ICs that performs the quadrature decoder, counter, and bus interface function. The HCTL-2021/2017 is designed to improve system performance in digital closed loop motion control systems and digital data input systems. It does this by shifting time intensive quadrature decoder functions to a cost effective hardware solution. The HCTL-2021/2017 consists of a quadrature decoder logic, a binary up/down state counter, and an 8-bit bus interface.
