Two points to add:
a) Buoyed by Mauro's recent discovery of the ever popular tda9887
existing in the Thomson DTT761x analog frontends (see
http://www.spinics.net/lists/vfl/msg22196.html), I revisited my interest
in identifying the TUV1236D/U's componentry (see
http://www.linuxtv.org/pipermail/linux-dvb/2005-November/005818.html
and http://www.linuxtv.org/pipermail/linux-dvb/2005-November/005820.htm).
Although the shape of the analog demodulator visible in that high res.
Anandtech photo
(http://www.anandtech.com/video/showimage.html?u=http://images.anandtech.com/reviews/video/ATI/hdtvwonder/tuner.jpg)
doesn't exactly conform to the drawings of the tda9887 in its datasheet,
it does, however, have the requisite 24 pin count. That, and given the
popularity of this IC, I'm fairly confident in my suspicions that it is
indeed the last piece of this puzzle .... (but I'm a self confessed
monkey too, so what do I know :P).
Anyways, in summary, it looks to be the case that the TUV1236D/U
consists of the Infineon TUA6034T tuner/pll + Philips TDA9887T analog
demodulator/pll + Ati/Nxt2004 (digital) demodulator.
b) In addition to interfacing with the cx88 and saa713x, provision
should also be made for the BT878A and the TL880 (when the time comes
for it) given this frontend's use on the cards mentioned here:
http://www.linuxtv.org/pipermail/linux-dvb/2005-October/005643.html
PS. obviously I was wrong about the BT878A and the Kworld, but it does
indeed apply to the case for the Fujiplus (see:
http://www.newegg.com/Product/ShowImage.asp?image=15-163-001-01.jpg,15-163-001-02.jpg,15-163-001-03.jpg,15-163-001-04.jpg,15-163-001-05.jpg&CurImage=15-163-001-02.jpg&Description=Fujiplus%20FD-3250%20PCI%20Interface%20Digital%20HDTV%20%20%20%20Card%20-%20Retail).
