SN65LVDS250 output duty cycle spec

Other Parts Discussed in Thread: SN65LVDS250, SN65LVCP404

Team,

 

My cusotmer is asking specification of SN65LVDS250 crosspoint switch's output duty cycle.

It seems to me it depends on input clock/data's duty cycle and added jitter.

pls, give me your advice.

 

Thanks,

Sang-Ho Kim

    SH,

     

    Since this is a buffer based design, the input data will have an impact on the output. Also, it is important to understand the data rate the device is being used at.  This device’s data rate is specified to ~2.0Gbps at this data rate there is likely to be some duty cycle distortion but the amount is not likely to have a material impact on the overall jitter performance.  Please note the eye pattern on the first page of the data sheet. If the customer is planning to use this device at much higher data rates, then I would suggest a device like SN65LVCP404 instead.

     

    Regrads,
