Data Sheet
The Terrestrial Tuner sections perform 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
ZL10320 via the ADC_IN[9:0] input pins, in the form of a 10-bit parallel signal.
The ZL10320 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
405TM subsystem. The PVR controller block contains an additional 64 level PID filter for the efficient selection of
the desired programme for recording.
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
www.DataSheetE4UN.Ccoomders (DENCs) for display on the TV via the on-chip 10-bit video DACs. The Video DACs can then produce
Analog Video in either Composite Video (CVBS), or Component Video (RGB or YPrPb).
Decoded Audio is output directly from the audio decoder sub-system to the I2S (Inter IC Sound) and S/PDIF
(Sony/Philips Digital InterFace) outputs.
The Decoded Audio and Video from the ZL10320 can either be provided via standard Analogue Video and Audio
connections to a Television Monitor, or can be used to provide the inputs to a UHF re modulator to provide a UHF
Analogue Television signal to connect to a standard analogue TV.
Free-to-Air Dual-Standard Terrestrial and Satellite PVR Receiver
The ZL10320 can be used to implement multi-standard DVB receiver with the addition of external demodulator
devices. Figure 3 on page 5 shows the block diagram of an example application of a dual-standard dual-channel
selectable Satellite and Terrestrial PVR receiver. Zarlink Semiconductor’s Satellite Tuner technology allows for the
DVB-S and DSS Satellite television standards to be received. With the advent of Free-to-view satellite services in
some countries, this concept has potential applications in regions where some TV services are available only on
one or other standard (Terrestrial or Satellite) but not both.
