Description
Zarlink Semiconductor has responded to market demand by integrating its key DVB-T compliant COFDM
demodulation technology with Set Top Box functionality (MPEG-2 A/V decoder and system interfaces) together with
a high performance CPU to offer a "DVB-T On-a-Chip" solution.
The ZL10310 DVB-T On-a-Chip, can address a wide range of DVB-T consumer electronic products. At the entry
level it can be used to build ultra-compact Free-To-View Digital TV adaptors (such as for FreeView in the UK), yet
consumes less than 4W of power in full operational mode.
This level of compactness also considerably eases the integration of DVB-T receiver technology inside integrated
Digital TV sets (iDTV's) where space considerations and thermal management are key design issues.
The ZL10310 is based upon an industry standard PowerPC 405
TM
RISC processor, which has Virtual and Memory
Management sub-systems. This permits the device to be effectively deployed in compelling applications such as
interactive Digital TV which are able to exploit the superior processing performance offered by the PowerPC
processor core.
The PowerPC
provides an ideal platform for running robust open standard operating systems such as Linux which
can benefit system developers in a number of key areas:
Unified software development environment, from entry level basic channel zapper systems through to fully
interactive high performance Digital Set Top Boxes.
Re-use of software code from multiple projects
Exploit software code developed in the Linux community.
Low cost-per-seat software development environment.
Familiar software development environment.
Royalty free.
Also available is the ZL10311 DVB-T On-a-Chip, which additionally offers Dolby
Digital
1
multi-channel audio
decoding, and Macrovision
TM
Copy Protection for applications requiring Dolby
Audio and Pay TV services.

1.0 Device Overview
Zarlink Semiconductor has designed the ZL10310 and ZL10311 System On a Chip (SoC) devices specifically for
DVB-T applications. Integrating a high performance PowerPC 405
TM
processor with robust industry proven
MPEG-2 audio and video decoding, OSD and a COFDM demodulator, the ZL10310 and ZL10311 deliver the
performance and functionality required for advanced Digital TV entertainment products. It enables the rapid design
and manufacture of cost-effective iDTV and Digital Audio Visual Home Entertainment Centers.
The enhanced ZL10311 also supports DVD playback with up to six Dolby
Digital
1
audio channels. In addition, by
integrating the COFDM demodulator, the ZL10310 and ZL10311 enable the implementation of very small footprint
TV Adaptor modules.
2.0 Device Interfaces
The following peripheral interfaces are available to the user. Apart from possible level translation and connector
buffering, no external devices are required to support any of the interfaces.
10-bit input that may be configured for an ADC input to the internal COFDM demodulator
Additional input bus for additional MPEG-2 Transport Sources

3.0 Typical Digital Television (DTV) Receiver
Figure 2 shows a typical Free to Air TV receiver block diagram employing a ZL10310 DTV-SoC device. In its
minimal configuration, the ZL10310 DTV-SoC device only requires a single 64 Mbit SDRAM, an audio DAC, and a
Flash ROM, which are in addition to a DVB-T tuner front end and a 10-bit analog to digital converter.
The Terrestrial Tuner section performs an independent down conversion of the received DVB-T signal from the
Antenna, to an IF frequency in the range of 30MHz to 57MHz, dependent on television system (typically 36.17MHz
Center Frequency, with
4MHz span). The analogue IF is then converted to the digital domain, with a 10-bit ADC,
clocked at 20.48MHz and the resulting Digital output is centered on 15.69MHz. This Digital signal is applied to the
ZL10310 via the ADC_IN[9:0] input pins, in the form of a 10-bit parallel signal.
The ZL10310 converts the digitized IF from a Terrestrial TV Tuner into an MPEG-2 Transport Stream, which can be
optionally de-scrambled (if CA scrambling is used by the broadcaster), and de-multiplexed into separate Packetised
Elementary Streams (PES), which are routed to the MPEG Audio and Video decoders, and SI data to the PowerPC
405
TM
subsystem.
Decoded Video can then be mixed and optionally scaled with On-Screen Display (OSD) Graphics generated by the
DTV application software. The resultant combination of video and graphics are then routed to the PAL/NTSC Digital
ENCoders (DENCs) for display on the TV via the on-chip 10-bit video DACs.
Decoded Audio is output directly from the audio decoder sub-system to the I
2
S and S/PDIF (Sony/Philips Digital
InterFace) outputs.
