SN75LVDS82: Can this device receive the signal from the compatible DS90C383B corresponding to SSCG?

shigekazu takada

Part Number: SN75LVDS82
Other Parts Discussed in Thread: DS90C383B, , DS90CF384, DS90CR286A

Is there a possibility that the signal from the DS90C383B with the CLK of the SSCG can not be received normally when receiving it with the SN75 LVDS 82?
It was not possible to judge whether SSCG correspondence to SN75 LVDS 82 was possible or not.

Hi Shigekazu-san,

We will check on this and get back to you early next week.

Hi Shigekazu-san,

Sorry for the delay, I am still looking into this. It’s a bit difficult to find this information since the device was released over 22 years ago, but I will have an answer/solution for you this week.

Regards,
I.K.

Hi Shigekazu-san,

I'm unable to find any information about the PLL architecture for the SN75LVDS82 so I can't comment on whether or not it will accept spread spectrum clocking.

However, all of the generation 1 DS90 deseriailzers have the same PLL architecture that allows for spread spectrum clocking. So I would recommend using the DS90CR286A or DS90CF384 instead of the SL75LVDS82.

Thank you for your reply.

I wanted to extract the cause of the problem but narrow it by oneself.

In addition, I will inform you that we are using the recommended combination in the circuit diagram that I checked.
