Hi,
We are looking for other solution of the pwm generater, all we need is:
300 or 600 HZ pwm with duty cycle ratio >1000. eg, 300HZ, min high of the PWM should be less than 3.3ms/1000= 3.3us
max could be less than 50%. as long as it can give me min 50%/1000, we are OK,
digital input is fine (we could put ADC), but no micro nor FPGA, this is a must.
thanks
Frank
