DRX 39xyK
Multistandard Demodulator for Analog TV / DVB-T / DVB-C
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
I2S 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.
