DS110DF111 Jitter specifications

D. Johnson
Intellectual 700 points

The data sheet does have much information on jitter specifications.  It does discuss typical transmit jitter and , but that is all.  Nothing on jitter generation, jitter transfer or industry standrads that it meets or exceeds. 

Does TI have any additional information on -

Jitter transfer characteristics ?

Jitter as it relates to reference clock ?

Does the device meet the jitter requirements (tolerance and generation) for IEEE 802.3ae (and others like OIF, ANSI, Telcordia,etc)

Thanks

Dave Johnson

    Hi Dave,

    The reference clock is used as more or less as a time-base, it does not affect the jitter performance of the retimer.

    My colleage will get back to you on the jitter plots.

    Hi Dave,

    The jitter transfer characteristics of this device are not available to post externally.  Please send me an email at lee.sledjeski@ti.com for continued discussion on specific implementations. 

    This device has already been used successfully in many 10G ethernet / SFP+ applications at multiple customers.

    The 25 MHz reference clock is only used to ensure fast positive lock to data under the most demanding conditions.  The output jitter is not impacted or influenced by the reference clock performance after lock is achieved.

    Regards,

    Lee
