About SN65LVDS9638 - signaling rate

Other Parts Discussed in Thread: SN65LVDS9638

Hello,

 

Regarding to the SN65LVDS9638, I have a question.

According to TI web site, it is available up to 150Mbps signaling rate.

But it seems that it is available up to 400Mbps signaling rate on datasheet.

(page 1,10)

“Typical Output Voltage Rise and Fall Times of 500 ps (400 Mbps).”

 

Could you please advise me, which is correctly signaling rate?

(150 or 400 Mbps?)

 

Regards,

    Hi Tao,

    Sorry for the long delay.

    Both values are valid. There is a typical relationship between signaling rate and distance achievable depending on the quality of the eye pattern at the receiver that is either desired or needed. Please refer section 10.1 at the datasheet for further details.

    Regards,

    Gerardo
