Post by thread:[PICLIST] cheap digital freq multiplier chips

People, I'm planning to buy frequency multipliers since I have a difficulty doing different circuits for different input frequencies. I've seen some from Engineered Components Company but they're quite some money for me. Each cost $30. Could someone give me some manufacturer of cheaper frequency multipliers?

Cypress semiconductor do a reasonable range of pll products: http://www.cypress.com/clock/ not sure if any of their parts will work down the the frequency you have though. you could also check out Pericom: http://www.pericom.com/products/sclock/index.html Regards, Simon -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

I don't know what frequency you are trying to multiply, but a PLL will always work. If the frequency is low (<5MHz) you can use a 2-chip solution with standard CMOS parts. There are equivalents for higher frequencies of this. Peter -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
