provide gigabit Ethernet on LPC4370

Hi everybody

I am using lpc-link2 (lpc4370) for a project which uses ADC in 60MHz(need 120MB/s for transfer). regarding the datasheet there is no serial protocol that can support this speed. there may be a solution that i can use an interface and send data in parallel then use for example gigabit ethernet rather than fast ethernet, however I don't know how! do you guys have any suggestion? thanks in advance for your help.

The interface with the highest throughput is the SDRAM interface. You can use an FPGA connected to this interface and convert it to gigabit ethernet. But I assume that this is expensive and and a lot of work.

The SGPIO interface is also pretty fast if you configure it for a 16-bit parallel output, this would be on the FPGA side a little bit easier to realize, but also here you have the cost and the development work on the FPGA side.

Then comes the LCD interface, 24-bit wide, also a relatively high throughput when you clock it on 50MHz.

Bernhard.
