Hello GSM BB hackers,
I wonder, would anyone here happen to know what are the main diffs
between the TWL3014 and TWL3025 ABB chips?
Not much ... For our purposes they're identical.
Hence me wondering if anyone here knows what the
actual differences
are...
I also recall seeing somewhere (don't remember where) that Iota
strictly means TWL3014, and that its successor (TWL3016?) is
supposedly called Syren rather than Iota and supports EDGE modulation.
No it doesn't.
If that is true, where does the TWL3025 fit into that
picture then?
Is it a Iota variant or a Syren variant?
I think they're all called "Iota" that's a generic designation for the
ABB.
It ought to be newer than TWL3016, right?
It is.
Does that mean it ought to support EDGE?
No it doesn't ... because the 3016 doesn't. Nor does the 3029 either.
If so, what
stands in the way of EDGE support in phones like GTA02 that use the
TWL3025 ABB? Lack of Calypso DSP support? Or an RF front-end that
isn't compatible with EDGE modulation?
Missing DSP support and missing ABB support.
Cheers,
Sylvain
