Hi expert,

May I know if there are any timing restrictions on TX and RX? How can we learn that the waveforms for TX and RX are adequate? thanks.

Hi Hangjie,

Please find the switching characteristics in datasheet section 6.8.

For your second question, can you please clarify a little bit more? What does it mean for waveforms are adequate?

Regards,

Sean

Hi Sean,

Thanks for your quick reply, how should I understand that Tbit's Max is 550ns? Is this rate related? If the communication rate is 500k, 1M and 2M respectively, can the tbit not be greater than 550ns? thanks.

Hi Hangjie,

That's the variation in the bit width as it propagates through the transmitter to the output and back through the receiver to the receiver output. For tbit(TXD)= 500ns (2Mbps communication), the bit time on RXD will be 550 ns max. If tbit(TXD) is longer than 500ns, the tbit(RXD) range will increase.

Sean
