Sorry for misunderstanding Christos' question, Terry. Since I hate spurs I've never used the internal PLL. W6XX clocked the AD9951 in excess of 700 MHz successfully, and without much temperature rise, I've used one for years at 536 MHz. Makes you wonder how much beyond 1 GHz the AD9910/AD9912 can be clocked. Hooking up a DDS and a PIC is only the beginning: eliminating board ground loops, shielding and filtering are necessary to eliminate the zillions of spurs that are possible in the real world. -----Original message----- From: "Terry" [EMAIL PROTECTED] Date: Thu, 08 May 2008 20:55:27 -0600 To: [email protected] Subject: [softrock40] Re: softrock for 2m?
