Reach 500MHz of clock output

[LordFeratum]

Hello guys!

First of all, I'm sorry for my bad english, it's not my first language and I'll try to do my best. Thanks you for understanding.

I need to reach 500MHz of clock output (square signal) on any pin (GPIO, SPI, I2C... whatever). Why I need it? Beacause I'm developing a SRAM chip to operate to 500MHz maximum. I need to test the reads and writes on the memory at the maximum frequency to determinate any kind of errors on the chip. Also, I need to modify the frequency to determinate the recommended frequency for the SRAM.

I have seen a project to turn the Raspberry Pi into a RF Transmitter. They can reach 100MHz on a single GPIO.

Is there any way to reach more frequency?

Thanks you very much for your answers!

No,

The pins are only meant to run up to about 50MHz

Sounds like you need a programmable oscillator, like the Si570. I2C control, with a range 10-945 MHz software-selectable.

Thanks for your answers! I'm very thankful!

scruss I don't just need the clock at 500MHz. I also need to control the synchronous bus, so I need to control the EC, R/W, and more lines. All my system must operate at 500MHz. Thanks you!

I'm thinking to use the HDMI output or Jack 3,5mm to inject the signal, but I think it wasn't productive.

Unfortunately I think raspbery pi can't reach my specifications.

If anyone has any ideas, i will be very grateful!

Best regards!
