DTVIIC(4)						   BSD Kernel Interfaces Manual 						 DTVIIC(4)

NAME

     dtviic, au8522, cx24227, lg3303, mt2131, nxt2k, zl10353, tvpll, xc3028, xc5k -- Inter IC (I2C) modules for DTV

DESCRIPTION

     The dtviic modules provide support for dtv(4) devices.  The dtviic module group includes tuners, demodulators, and analog video decoders.

     The usual hardware structure consists of a host controller (connected for instance via usb(4) or pci(4)) that provides the data moving facil-
     ities (for the analog or digital video streams) and an iic(4) bus over which the other chips can be configured.

     For example, a typical dtv(4) setup would look like this:

	   1.	Initialize transport stream (TS) port on the host controller.

	   2.	Configure the demodulator that ``demodulates'' the information from an intermediate frequency (IF) that is provided to it by the
		associated tuner.  This step typically includes setting the desired quadrature amplitude modulation (QAM) and bandwidth, among
		other things.

	   3.	Configure the tuner.  Typically this step includes at least setting the frequency.

	   4.	Start TS transfer (using DMA transfers or USB high speed transfers).

     The supported demodulators include:

	   au8522      Auvitek AU8522 ATSC/QAM64/QAM256 demodulator

	   cx24227     Conexant CX24227 ATSC/QAM64/QAM256 demodulator

	   lg3303      LG LGDT3303 ATSC/QAM64/QAM256 demodulator

	   mt2131      MicroTune MT2131 ATSC demodulator

	   nxt2k       NxtWave Communications NXT2004 ATSC demodulator

	   zl10353     Zarlink ZL10353 (Intel CE623x) COFDM/DVB-T demodulator

     The supported tuners are:

	   tvpll       Generic PLL-based tuners

	   xc3028      XCeive XC3028 analog and digital tuner

	   xc5k        Xceive XC5000 analog and digital tuner
