TMDSRSLVR: What are the signal waveforms of the pins in the picture?

Genius 3095 points

Part Number: TMDSRSLVR

What are the signal waveforms of the pins in the picture? Frequency? Amplitude? Waveform? (J10-6, GPIO2, GPIO3)

Best regards

  • GPIO2- PWM sine is a pulse width modulated signal representing the carrier frequency, PWM frequency is about ~ 240KHz.
    GPIO3- PWM_dither is supposed to be a random pwm signal of small value that can be for testing purposes. You can choose to keep it zero always.
    The signal of J10-6 with respect to J10-7 is a bipolar sinusoidal carrier signal of magnitude nearly +/- 5V range depending on the modulation index set for the PWM pulses generating the sine wave. If a lower mag is preferred, reduce the mod index of pwm signal.
