Cyclone III EP3C120F780C7 @ 150MHz?

--- Quote Start ---

Hi,

I am designing a video processing system on a Cyclone III (EP3C120F780C7). The FPGA is expected to run at a clock of at least 150 MHz. Is there anyone has experienced a system that fast?

I need your responses to make decision.

TIA

There are some of the Altera reference designs for Cyclone III which are near to the speed you have quoted:

1. 122.88 MHz: http://www.altera.com/support/refdesigns/sys-sol/wireless/ref-wcdma-ducddc.html

2. 100 MHz: http://www.altera.com/support/refdesigns/sys-sol/indust_mil/ref-des-secur-mem.html

The embedded multipliers in Cyclone III devices can operate at 260 MHz. There is a white paper on "Using Cyclone II FPGAs for Wireless Applications" (http://www.altera.com/literature/wp/wp-01017.pdf) which has reference to using these FPGAs in the range 144-203MHz.
