Insignia NS-HDTUNE Take Apart/Exploration

 

Well, I was bored and curious...so if you've been wondering what's
inside this (or probably almost any other) HD Radio tuner, here it is:

(warning: the following link contains large quantities of pictures and
is therefore not friendly to those who have bandwidth caps or are
charged on a "quantity of data transferred" basis)

It's not quite finished yet, some items need more explanation. I haven't
verified the clock rate of the DSP but believe it to be correct. I also
need to upload the larger photos and add the navigation links to the
page. But for those who are curious, it ought to do for now.

No tuners were harmed in the making of this page or in the exploration.
By the way, I have been completely unimpressed by the performance of
this tuner. (I'm so glad I paid nowhere near the retail price!) I'd
recommend you look at something else if you want to listen to HD radio.

Hi!


HD Radio is the digital radio broadcast standard in the US. It's a
development from a company known as iBiquity. iBiquity primarily
functions as a licensor of the technology to others.

HD Radio broadcasts are delivered alongside the current analog AM or FM
broadcasts, and on the same frequencies.

Outside of the US, other methods are used, such as Digital Audio
Broadcasting (DAB) or Digital Radio Mondiale (DRM).
