Hi team,

Is DS90C387A pin to pin DS90C387?

Customer is using DS90C387 and want to find an alternative with lower price.

Thanks,

Miranda

hello,

The DS90C387/CF388 chipset is electrically similar to the DS90C387A/CF388A. The DS90C387A/CF388A ONLY is recommended if support of longer cable drive is not required. DC Balance data transmission and cable deskew features are disabled to minimize overall power dissipation. The devices will also directly inter-operate with
existing FPD-Link devices for backward compatibility.

regards,

Steven

Hi Steven,

Customer uses 2 meter length cable. Is it OK for both DS90C387A and DS90C387?

Thanks,

Hello,

the answers to your all questions can be found in TI's d/s, pls read the data for this message. generally, 5m is limited considering clock rate and cable quality.

pls understand this is on high speed serial link design, it is NOT only on serdes's electrical spec.

regards,

Steven
