68HC68W1 Datasheet (Intersil Corporation) - CMOS Serial Digital Pulse Width Modulator

68HC68W1, CMOS Serial Digital Pulse Width Modulator

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
