Description  
High level software interface for minimum  
development time  
The ZL10312 is  
a
QPSK/BPSK 1 - 45 MSps  
demodulator and channel decoder for digital satellite  
television transmissions to the European Broadcast  
Union ETS 300 421 specification. It receives analogue  
I and Q signals from the tuner, digitises and digitally  
demodulates this signal, and implements the complete  
DVB/DSS FEC (Forward Error Correction), and de-  
scrambling function. The output is in the form of  
MPEG2 or DSS transport stream data packets. The  
ZL10312 also provides automatic gain control to the RF  
front-end device.  
Up to ±22 MHz LNB frequency tracking  
DiSEqC™ v2.2: receive/transmit for full control of  
LNB, dish and other components  
Compact 64 pin LQFP package (7 x 7 mm)  
Sleep pin gives ~1,000 fold reduction in power to  
help products meet ENERGY STAR®  
requirements  
Applications  
The ZL10312 has a serial 2-wire bus interface to the  
control microprocessor. Minimal software is required to  
control the ZL10312 because of the built in automatic  
search and decode control functions.

ZL10312  
Data Sheet  
Overview  
The ZL10312 is a QPSK/BPSK 1 - 45 MSps demodulator and channel decoder for digital satellite television  
transmissions compliant to both DVB-S and DSS standards and other systems.  
A Command Driven Control (CDC) system is provided making the ZL10312 very simple to program. After the tuner  
has been programmed to the required frequency to acquire a DVB transmission, the ZL10312 requires a minimum  
of five registers to be written.  
The ZL10312 provides a monitor of Bit Error Rate after the QPSK module and also after the Viterbi module. For  
receiver installation, a high speed scan or 'blind search' mode is available. This allows all signals from a given  
satellite to be evaluated for frequency, symbol rate and convolutional coding scheme. The phase of the IQ signals  
can be automatically determined.  
Full DiSEqC v2.x is provided for both writing and reading DiSEqC messages. Storage in registers for up to eight  
data bytes sent and eight data bytes received is provided.

ZL10312  
Data Sheet  
1.0 Functional Overview  
1.1 Introduction  
ZL10312 is a single-chip variable rate digital QPSK/BPSK satellite demodulator and channel decoder. The  
ZL10312 accepts base-band in-phase and quadrature analogue signals and delivers an MPEG or DSS packet data  
stream. Digital filtering in ZL10312 removes the need for programmable external anti-alias filtering for all symbol  
rates from 1 - 45 MSps. Frequency, timing and carrier phase recovery are all digital and the only feed-back to the  
analogue front-end is for automatic gain control. The digital phase recovery loop enables very fine bandwidth  
control that is needed to overcome performance degradation due to phase and thermal noise.  
All acquisition algorithms are built into the ZL10312 controller. The ZL10312 can be operated in a Command Driven  
Control (CDC) mode by specifying the symbol rate and Viterbi code rate. There is also a provision for a search for  
unknown symbol rates and Viterbi code rates.  
1.2 Analogue-to-Digital Converter and PLL  
The A/D converters sample single-ended or differential analogue inputs and consist of a dual ADC and circuitry to  
provide improved SiNaD (Signal-Noise and Distortion) and channel matching.  
The fixed rate sampling clock is provided on-chip using a programmable PLL needing only a low cost 10 to 16 MHz  
crystal. Different crystal frequencies can be combined with different PLL ratios, depending on the maximum symbol  
rate, allowing a very flexible approach to clock generation. An external clock signal in the range 4 to 16 MHz can  
also be used as the master clock.  
1.3 QPSK Demodulator  
The demodulator in the ZL10312 consists of signal amplitude offset compensation, frequency offset compensation,  
decimation filtering, carrier recovery, symbol recovery and matched filtering. The decimation filters give continuous  
operation from 2Mbits/s to 90Mbits/s allowing one receiver to cover the needs of the consumer market as well as  
the single carrier per channel (SCPC) market with the same components without compromising performance, that  
is, the channel reception is within 0.5dB of theoretical. For a given symbol rate, control algorithms on the chip  
detect the number of decimation stages needed and switch them in automatically.  
The frequency offset compensation circuitry is capable of tracking out up to ±22.5 MHz frequency offset. This  
allows the system to cope with relatively large frequency uncertainties introduced by the Low Noise Block (LNB).  
Full control of the LNB is provided by the DiSEqC outputs from the ZL10312. Horizontal/vertical polarisation and an  
instruction modulated 22kHz signal are available under register control. All DiSEqC v2.x functions are implemented  
on the ZL10312. An internal state machine that handles all the demodulator functions controls the signal acquisition  
and tracking. Various pre-set modes are available as well as blind acquisition where the receiver has no prior  
knowledge of the received signal. Fast acquisition algorithms have been provided for low symbol rate applications.  
Full interactive control of the acquisition function is possible for debug purposes. In the event of a signal fade or a  
cycle slip, the QPSK demodulator allows sufficient time for the FEC to re-acquire lock, for example, via a phase  
rotation in the Viterbi decoder. This is to minimise the loss of signal due to the signal fade. Only if the FEC fails to  
re-acquire lock for a long period (which is programmable) would QPSK try to re-acquire the signal.  
The matched filter is a root-raised-cosine filter with either 0.20 or 0.35 roll-off, compliant with DSS and DVB  
standards. Although not a part of the DVB standard, ZL10312 allows a roll-off of 0.20 to be used with other DVB  
parameters. An AGC signal is provided to control the signal levels in the tuner section of the receiver and ensure  
the signal level fed to the ZL10312 is set at an optimal value under all reception conditions.  
The ZL10312 provides comprehensive information on the input signal and the state of the various parts of the  
device. This information includes signal to noise ratio (SNR), signal level, AGC lock, timing and carrier lock signals.  
A maskable interrupt output is available to inform the host controller when events occur.

1.4 Forward Error Correction  
The ZL10312 contains FEC blocks to enable error correction for DVB-S and DSS transmissions. The Viterbi  
decoder block can decode the convolutional code with rates 1/2, 2/3, 3/4, 5/6, 6/7 or 7/8. The block features  
automatic synchronisation, automatic spectral inversion resolution and automatic code rate detection. The trace  
back depth of 128 provides better performance at high code rates and the built-in synchronisation algorithm allows  
the Viterbi decoder to lock onto signals with very poor signal-to-noise ratios. A Viterbi bit error rate monitor provides  
an indication of the error rate at the QPSK output.  
The 24-bit error count register in the Viterbi decoder allows the bit error rate at the output of the QPSK demodulator  
to be monitored. The 24-bit bit error count register in the Reed-Solomon decoder allows the Viterbi output bit error  
rate to be monitored. The 16-bit uncorrectable packet counter yields information about the output packet error rate.  
These three monitors and the QPSK SNR register allow the performance of the device and its individual  
components, such as the QPSK demodulator and the Viterbi decoder, to be monitored extensively by the external  
microprocessor. The frame/byte align block features a sophisticated synchronisation algorithm to ensure reliable  
recovery of DVB and DSS framed data streams under worst case signal conditions. The de-interleaver uses  
on-chip RAM and is compatible with the DVB and DSS algorithms. The Reed-Solomon decoder is a truncated  
version of the (255, 239) code. The code block size is 204 for DVB and 146 for DSS. The decoder provides a count  
of the number of uncorrectable blocks as well as the number of bit errors corrected. The latter gives an indication of  
the bit error rate at the output of the Viterbi decoder. In DVB mode, spectrum de-scrambling is performed  
compatible with the DVB specification. The final output is a parallel or serial transport data stream; packet sync;  
data clock; and a block error signal. The data clock may be inverted under software control.

Note: The crystal frequency should be chosen to ensure that the system clock would marginally exceed the  
maximum symbol rate required, e.g. 10.111 MHz with a multiplier of x9 will give a 91 MHz system clock to  
guarantee 45 MSps operation.
