Questions about the optimal design that can design 8 port 802.3bt Class8 using LTC4291-1 & LTC4292

Customer wants to develop 8 ports of PSE with LTC4291-1 and LTC4292.

When configuring 8 ports with 4-Pair (802.3bt Class8-71W), please let the customer know how designing can minimize the price.

ex) 2* (LTC4291-1 & LTC4292) = 8 port (4 pair) => Is there a more efficient way to organize the profit than this one?

    Currently the LTC4291-1/LTC4292 chipset is the only released 802.3bt 4-Pair PSE controller by ADI.  If the customer schedule is immediate for an 8-port,4-pair 802.3 bt PSE application, the customer will have to use two of the LTC4291-1/LTC4292 4-port PSE chipset solutions.  Continue to check ADI product offerings for future released PSE controllers.
