ADS54J54: Polarity of SYNCb pins when it starts transmitting K28.5 character

Hello,

I have a question about ADS54J54.

[Background]

There is a description in the D/S P.27 7.3.3.1 JESD204B Initial Lane Alignment (ILA) as follows.

<D/S>

Upon detecting a logic low on the SYNCbAB input pins, the ADS54J54 device starts transmitting comma (K28.5) characters on channels A and B to establish code group synchronization.

Upon detecting a logic high on the SYNCbCD input pins, the ADS54J54 device starts transmitting comma (K28.5) characters on channels C and D to establish code group synchronization.

[Q]

Is the polarity of SYNCbCD really reverse to SYNCbAB when it starts transmitting K28.5 ?

Is this (Bold) an error ?

Best Regards,

Hiroshi Katsunaga
