QUADRATURE CLOCK CONVERTER
April 2006
DISCONTINUED
FEATURES: • x1, x2 and x4 mode selection • Up to 16MHz output clock frequency • INDEX input and output • UP/DOWN indicator output • Programmable output clock pulse width • On-chip filtering of inputs for optical or
magnetic encoder applications. • TTL and CMOS compatible I/Os • +4.5V to +10V operation (VDD - VSS) • LS7082N (DIP); LS7082N-S (SOIC ) - See Figure 1
DESCRIPTION: The LS7082N is a CMOS quadrature clock converter. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B Inputs of the LS7082, are converted to strings of Up Clocks and Down Clocks.
