68HC68W1 - CMOS Serial Digital Pulse Width Modulator

Description

The CDP68HC68W1 modulates a clock input to supply a variable frequency and duty-cycle output signal.

Three 8-bit registers (pulse width, frequency and control) are accessed serially after power is applied to initialize device operation.

Features

  • Programmable Frequency and Duty Cycle Output.
  • Serial Bus Input; Compatible with Motorola/Intersil SPI Bus, Simple Shift-Register Type Interface.
  • 8 Lead PDIP Package.

CDP68HC68W1 March 1998 CMOS Serial Digital Pulse Width Modulator Description The CDP68HC68W1 modulates a clock input to supply a variable frequency and duty-cycle output signal. Three 8-bit registers (pulse width, frequency and control) are accessed serially after power is applied to initialize device operation. The value in the pulse width register selects the high duration of the output period. The frequency register byte divides the clock input frequency and determines the overall output clock period. The input clock can be further divided by two or a low power mode may be selected by the lower two bits in the control register. A comparator circuit allows threshold control by setting the output low if the input at the VT pin rises above 0.75V.
