Part Number: DS125BR820
Hi, I want to use one 8ch Repeater at main board and 2 ch repeater at line card. If DS125BR820 (or DS125BR800A) is used at main board, how to select the 2ch repeater chip at line card? Is DS125BR111 suitable?
Is there any selection guide about repeaters or retimers?
In our design, we have 10G SFP+ line card and 5G QSGMII card. The SFP+ card has 4 SFP+ module and 4 SFP+ lanes. The QSGMII card has 1 QSGMII channel. What is the recommended repeater or retimer chipset for my design?
Thanks a lot.
In reply to Michael Lu (Santa Clara):
Bellow is the system diagram. Maximum 10G trace length is about 10000mil, and MAX 5G trace length is about 20000mil.
The insertion loss of the connector is about -1.8dB at 10GHz and the return loss about -10dB at 10GHz.
In reply to ZhongHe Jin:
When place the repeaters, shall I put them at the RX side? That is for TX path, put the repeater at the line card, and for RX, at the main board.
