NXP silicon tuner
TDA18292HN
Ultra low power Terrestrial and Satellite
multi-band Silicon Tuner for portable TV
Optimized for digital TV reception in low power appliances, NXP’s new generation terrestrial and
satellite silicon tuner TDA18292HN covers DVB-T, DVB-H, DVB-SH, T-DMB and ISDB-T standards.
This highly integrated, 5-in-1 solution significantly reduces application costs, and improves TV
reception quality in portable applications. Low power dissipation combined with high immunity to
other cellular and connectivity standards make it ideal for a wide variety of portable and handheld
applications including notebooks, USB sticks, multimedia / DVD players, mobile phones and
navigation devices.
Key benefits
Improved TV reception and image quality
Increased operating time and lower battery costs due
to low power dissipation
Reduced board size and overall cost due to lower external
passive component count
Ready for multi-tuner configuration (antenna diversity)
Standard Zero-IF output interface to channel decoder
Easy to integrate in System-in-Package and MCM solutions
Key features
DVB-T, DVB-H, DVB-SH, T-DMB and ISDB-T applications
MBRAI 2.0 and Nordig V1.0.3 compliant
Wide dynamic AGC: 70 dB range, 0.5 dB control step
Multiple reference clock frequency compliancy:
- 16 MHz for quartz (XO)
- 19.2, 26, 38.4 and 52 MHz for external reference (e.g. TCXO)
2.7 V analog / 1.8 V digital supply
Small form factor 32-pin HVQFN package, only 5 mm x 5 mm
Key applications
Mobile phones
Portable LCD TVs and multimedia / DVD players
PDAs, notebook PCs and USB sticks
Portable navigation devices (GPS)
Handheld games
Benefiting from a direct down-conversion zero-IF radio
architecture, the TDA18292 makes a very compact,
high performance and low power solution. Excellent sensitivity,
due to a noise figure of less than 3dB, is complemented by
high immunity to cellular and connectivity standards – crucial
in applications such as mobile phones. Power consumption is
extremely low: only 20 mW in DVB-H, 80 mW in T-DMB and
170 mW in DVB-T.
A clear advantage
The tuner includes all the functions required to perform
digital TV reception, from RF input to baseband I/Q outputs.
It includes a balanced low-noise amplifier, complex mixer,
channel filters with built-in self calibration and a complete
RF PLL with fully integrated VCO, so no balun is required.
Programming is made easy through its I2C serial interface, and
it is possible to control two different tuners with a single line
thanks to an address select pin. A dedicated turn-on/-off pin
allows power reduction for time sliced applications and gain
is programmable in 0.5 dB steps using two up / down pins.

Making product integration easier, the PLL can operate
across a range of clock frequencies, and either a simple
crystal oscillation or a TCXO can be used for clock frequency
generation.
Evaluation kit
Our TDA18292 evaluation kit makes it simple for hardware
engineers to modify programmable settings and customize
operation. It includes tuner daughterboard, channel
decoder board for system testing, quick start guide, product
specification, application note and PC-based control software.
The tuner daughterboard can be easily connected to other
zero-IF channel decoders.
Multi-standard and multi-band capability
NXP’s TDA18292 is compliant with the following standards:
Terrestrial Digital Video Broadcast (DVB-T)
Handheld DVB (DVB-H)
Satellite services to Handheld (DVB-SH)
Terrestrial Digital Multi-media Broadcasting (T-DMB)
Integrated Services Digital Broadcasting –
