DS100BR210: CML receiver input level

Ruixin Feng

Part Number: DS100BR210
Other Parts Discussed in Thread: DS100BR410,

Hi team,

There are 3 questions need your help:

1. for DS100BR210 CML receiver input level Vtx, where is the differential measurement point? Is it same as TPA in DS100BR410 datasheet described?

2. The spec of Vtx, the max value is 1600mVpp. Is it the peak-to-peak value of (IN+)-(IN-) or peak-to-peak of (IN+)?

3. What's the difference between DS100BR210 and DS100BR410? Is DS100BR410 as 4-channel version for DS100BR210? Are they same usage and application? 

Thanks!

    Greetings Rayna,

    1). This is source transmit level. For example this ASIC or FPGA transmit leve before the transmission line.

    2). Peak-to-peak (IN+)-(IN-).

    3). Main difference is MODE pin for DS100BR210. BR210 allows KR training to pass through.
