BCM53134O Datasheet 2.5GbE/SerDes Timing

The datasheet on page 133 shows different signalling speed 1.25GBaud/3.125GBaud for the input/output timing at 2.5GbE/SerDes.

What are the correct values?

Hi,

BCM53134O SGMII interface supports 1Gbps and 2.5Gbps speed.

Right, it is typo in datasheet [2.5GbE/SerDes Timing] section. For input timing, the receive Data Signaling Speed is 3.125 Gbaud and not the 1.25 Gbaud.

The datasheet will to update to correct the typo in next update release.

 

Thanks,

Ryan
