Anyone working on a Si4770 design?

rsavas · 30th October 2012, 01:51 PM

Just wondering if anyone has used this new part. I have used the Si4735 and now want to go to the next step.

Hi rsavas,

I just began looking into tuner kits/PCBs/designs, and was really disappointed by the paucity of kits and PCBs available. After looking around I found, and liked, the si4770 & Si4777 chips, but designing a tuner around one of these chips is beyond my ability. All I can say is that if you decide to go ahead and design a board I'm willing to chip in some money to have a few prototypes made, if I get to build one of the prototypes.

My concern is whether or not any one else is interested. Judging by the response to your post, and a search in the diyAudio forum for anything related to radio tuners, we may be the only ones listening to your design.

Hi Byron,
Thanks for replying to my thread. Well you are correct, you are the only one thus far showing an interest, enough to respond. I have the PCB designed already, so just have to fab, solder, test & write the software. One of my winter projects. I wondering if anyone wanted to help, but no interest, so I am on my own at this time. You may what to look at the kit from Elektor, as that maybe better suited for what you are requiring.
The Elektor DSP radio (100126-91) - ELEKTOR.com | Electronics: Microcontrollers Embedded Audio Digital Analogue Test Measurement
Now that I look, it is saying "Sold Out". The code is still available.
I guess this why I roll my own!!
Also try Birkhard Kianka's site, he wrote the Elektor articles,need to translate as this is in German
Das Elektronik-Labor
HF
Sparkfun Electronics have a few Si4735 kits, as well, check them out.

Cheers
Rick
