1 Description
The AF9013/13S/15 DVB-T COFDM demodulator is a versatile second-generation single-chip IC that
supports multiple interfaces including serial and parallel MPEG2-TS and embedded USB 2.0 interface with
built-in de-multiplexer. It is compliant with both ETSI EN 300 744 and Nordig Unified 1.0.2, and it can
operate at 2K or 8K mode with 6, 7, or 8MHz bandwidth. All modulations (QPSK, 16QAM, 64QAM), code
rates (1/2, 2/3, 3/4, 5/6, 7/8), and guard intervals (1/4, 1/8, 1/16, 1/32) are supported and automatically
detected from the TPS parameters.
AF9013/13S/15 integrates a 10-bit analog-to-digital converter (ADC) capable of delivering the
performance required for all modulations and code rates of DVB-T. It supports direct sampling of IF
(e.g., 36.125 MHz or 43.75 MHz) or low IF (e.g., 4.57MHz) signals.
The device uses the most advanced digital signal processing techniques to combat various impairments
encountered in fixed, portable, and mobile DVB-T channels.
AF9013/13S/15 provides single AGC or dual RF/IF AGC control options for maximal flexibility in tuner
selections. The AGC control loop bandwidth is designed to track a wide dynamic range of the received
signal levels for slow or fast channel variations.
In AF9013/13S/15, an active impulse noise rejection algorithm removes the detrimental effects of the
impulse noise and significantly improves the robustness of TV reception against interference from vehicles
and electrical appliances.
Co-channel interference is actively searched and rejected by a digital notch filter in AF9013/13S/15. The
digital notch filter is enabled only when the interference is present to avoid any unnecessary signal loss.
Adjacent channel interference is rejected by precisely controlled digital filters for 6, 7, and 8MHz
bandwidth. This makes it possible to use a single 8MHz SAW filter independent of the bandwidth used.
The all-digital synchronization tracking loops of AF9013/13S/15 are capable of recovering carrier
frequency offsets as large as ±500 kHz and tolerating crystal jitters as large as ±100ppm. The adaptive
FFT window position tracking loop in AF9013/13S/15 accurately identifies pre-echo or post-echo multipath
channels even in highly mobile environments. Therefore, inter-symbol interference (ISI) and inter-carrier
interference (ICI) is greatly reduced.
In AF9013/13S/15, the common phase error caused by tuner phase noise is corrected by a joint channel
estimation and phase noise tracking algorithm, thus enabling the use of low cost tuners. Besides, the
multi-dimensional channel estimation and tracking scheme in AF9013 and AF9015 adaptively adjusts its
internal parameters to reflect the different requirements in fixed, portable, or mobile channels. Hence,
optimal performance can be achieved for all DVB-T applications. AF9013S, on the other hand, is
optimized for performance in stationary environments.
AF9013/13S/15 provides a comprehensive set of performance monitoring parameters accessible through
the 2-wire bus. These parameters include signal strength and signal quality indicators, post-Viterbi bit
error rate, Reed-Solomon packet error rate, TPS lock and MPEG Sync lock indicators, carrier and crystal
offsets, and many more.
AF9015 also includes a serial input interface for accepting a secondary MPEG2 transport stream (TS)
input, thus enabling applications such as picture-in-picture (PIP) and personal video recorder (PVR). It
also provides a serial interface for concurrent MPEG2 TS output, and can be easily incorporated into
devices with dual display.
