product information the trident drx 39xyk is a unique, multis- tandard, 3-in-1 demodulator. designed for a wide range of hybrid receiver applications, the drx 39xyk demodulates analog / dvb- t / dvb-c television broadcast signals. ver- sions with optional integrated audio demod- ulator and stereo decoder are available as well. supported standards include world- wide analog broadcast (atv), dvb-c (itu- t j.83, annex a, c) and dvb-t (ets 300744). the drx 39xyk combines existing, field- proven trident demodulator ip into a single- chip device. the if-input signal is demodu- lated and output as either transport stream (ts), or analog cvbs and sif signals. ver- sions with the optional integrated stereo decoder provide digital audio via standard i 2 s interface. the drx 39xyk provides significant pcb real estate benefits. combining three demodulators into a single chip, trident offers the world?s smallest multistandard hybrid demodulator in a qfn64 package (9 9 mm). the drx 39xyk is a member of the trident drx family, offering pin- and sw driver compatibility to the trident drx 394yj (ntsc / atsc / qam demodulator). designed with the complete system solution in mind, drx 39xyk enables highly opti- mized adjacent channel performance by integrating a broadband input power detec- tor. the api-based software interface enables effortless implementation into any system. compatibility with existing trident demodulator products reduces engineering costs by maximizing the re-use of existing software and product experience. main features ? dvb-t demodulator with excellent adja- cent-channel and co-channel perfor- mance, exceeding receiver specifica- tions: nordig-unified v2.0, dtg, eicta, and others ? digital cable demodulator with outstand- ing phase noise performance supporting itu-t j.83 annex a (dvb-c, eurodoc- sis) and c (japan) ? field-proven analog standard (atv) ntsc / pal / secam vif demodulator, with cvbs output ? field-proven atv (am / nicam / fm) audio demodulator with sif output ? field-proven audio demodulator / decoder (am / nicam / fm / btsc / a2) (optional) ? fm radio with rds / rbds ? integrated microprocessor provides a high-level command interface to the host processor and downloadable microcode ? interfaces: ? if and rf (optional) gain control out- puts to tuners ? sense input for tuner if output signal ? parallel and serial mpeg ts outputs ? analog cvbs and sif output ?i 2 s digital audio output for analog tv audio (f s = 8?48 khz/ 16?32 bit) (optional) ?i 2 c slave interface ? jtag ? gpio ? low power consumption ? support for low- / near-zero if ? selectable i 2 c addresses ? packages: ? qfn48 ? qfn64 drx 39xyk aug/2008 drx 39xyk multistandard demodulator for analog tv / dvb-t / dvb-c datasheet.in
