DS64BR111: doubling the resources

Part Number: DS64BR111
Other Parts Discussed in Thread: DS64BR401, DS100BR410

Several years back I used this part to create a SATA link: DS64BR111 Ultra Low Power 6.4 Gbps 2-Channel Repeaters with Input Equalization and Output De-Emphasis. I creates  one bidirectional transmission link. I am looking for option to double the resources so to create SATA redriver for two bidirectional links. Could you recoment me a part that would have excatly the same functions but has double the channels?  I see DS64BR401 but it is not exactly the same and has 4 channels as oppose to two.

Thanks,

Jacek
