You're comparing apples & oranges. The Broadcom devices you cited address a different market segment. The Inifineon/AMCC devices referenced perform "pointer processing" at the 10G level... the Broadcom devices do not.
The difference is subtle, but the Infineon/AMCC devices are really quite different in function from the Broadcom 85xx parts.
Think of the Inifineon device as a "four-pack" of the AMCC apple. The Broadcoms are still oranges.
Correction. Already have hit and are lighting up the channel as we speak.
Try Broadcom's BCM8501 - 9.953 STS-192/STM-64 POS/ATM Framer and Mapper. Pure CMOS with total power consumption just over two watts !
Not enough. They also recently released a 10 Gig G.709 transport wrapper device with integrated STS-192/STM-64 transceiver, the BCM8511.
