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 clo
