Description
The CE6353 is a superior fourth generation fully compliant ETSI ETS300 744 COFDM demodulator that exceeds, with margin, the performance requirements of all known DVB-T digital terrestrial television standards, including Unified Nordig and DTG.
A high performance 10 bit on-chip ADC is used to sample the 44 or 36 MHz IF analog signal. Advanced digital filtering of the upper and lower channel enables a single 8 MHz channel SAW filter to be used for 6, 7 and 8 MHz OFDM signal reception. All sampling and other internal clocks are derived from a single 20.48 MHz crystal or a 4 MHz clock input, the tolerance of which may be relaxed as much as 200 ppm.
The CE6353 has a wide frequency capture range able to automatically compensate for the combined offset introduced by the tuner xtal and broadcaster triple frequency offsets.
An on-chip state machine controls all acquisition and tracking operations of the CE6353 as well as controlling the tuner via a 2-wire bus. Any frequency range can be automatically scanned for digital TV channels. This mechanism ensures minimal interaction, maximum flexibility and fast acquisition - very low software overhead.
Also included in the design is a 7-bit ADC to detect the RF signal strength and thereby efficiently control the tuner RF AGC.
Users have access to all the relevant signal quality information, including input signal power level, signal-to-noise ratio, pre-Viterbi BER, post-Viterbi BER, and the uncorrectable block counts. The error rate monitoring periods are programmable over a wide range.
The device is packaged in a 10 x 10 mm 64-pin LQFP and is very low power.

Description
The CE6313 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, implements the complete DVB/DSS FEC (Forward Error Correction) and descrambling function. The output is in the form of MPEG2 or DSS transport stream data packets. The CE6313 also provides automatic gain control to the RF front-end device.
The CE6313 has a serial 2-wire bus interface to the control microprocessor. Minimal software is required to control the CE6313 because of the built in automatic search and decode control functions.

GENERAL DESCRIPTION
The XR-2211 is a monolithic phase-locked loop (PLL) system especially designed for data communications applications.
It is particularly suited for FSK modem applications.
It operates over a wide supply voltage range of 4.5 to 20V and a wide frequency range of 0.01Hz to 300kHz.
It can accommodate analog signals between 10mV and 3V, and can interface with conventional DTL, TTL, and ECL logic families.
The circuit consists of a basic PLL for tracking an input signal within the pass band, a
quadrature phase detector which provides carrier detection, and an FSK voltage comparator which provides FSK demodulation.
External components are used to independently set center frequency, bandwidth, and output
delay.
An internal voltage reference proportional to the power supply is provided at an output pin.
The XR-2211 is available in 14 pin packages specified for military and industrial temperature ranges.

DESCRIPTION
The LT®5517 is a 40MHz to 900MHz quadrature demodulator optimized for high linearity receiver applications where high dynamic range is important. It is suitable for communications receivers where an RF or IF signal is directly converted into I and Q baseband signals with a bandwidth up to 130MHz. The LT5517 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, broadband quadrature generator derived from an on-chip divide-by-two circuit. The superior linearity and low noise performance of the LT5517 is achieved across its full frequency range. A wellbalanced divide-by-two circuit generates precision quadrature LO carriers to drive the I mixer and the Q mixer. Consequently, the outputs of the I-channel and the Q-channel are well matched in amplitude, and their phases are 90° apart. The LT5517 also provides excellent 50W impedance matching at the 2XLO port across its entire frequency range.

Description
 STV83xy family is the latest sound processor from STMicroelectronics. Based on STV82xy
family success, the new STV83x8(US) and STV83x7 (EU/Asia/Middle East/Africa) are
particularly intended for the mainstream flat TV market, paving the way to enhanced sound
experience at the end customer level.

 One of the new STV83xy family key function is to ensure the proper demodulation of analog
broadcast thanks to its “Autostandard” functionality, a digital standard search engine.
The demodulation functionality based on the field proven STV82xy family, is highly robust in
all concerned area, even where overmodulation is dominant.
Five (5) analog audio auxiliary inputs and three (3) auxiliary SCART compliant outputs are
available and aimed at reducing the bill of material (BOM) by removing audio switches and
buffers.

 STV83xy products are designed to fulfill all new digital or hybrid TV digital connectivity
needs thanks to a SPDIF input (bypass only) and two (2) synchronous/asynchronous inter
sound interface (I²S). One of the latter supports Dolby Digital 5.1 PCM audio, which
emphasizes on product differentiation by driving directly analog and digital multichannel
outputs. Thanks to this direct drive, TV manufacturers can fully take advantage of sound
virtualizers such as TruSurround XT (with TruSurround XT 5.1 Digital differentiated logo)
and ST Omnisurround, or be the first to feature the brand new SRS TruSurround HD, which
STMicroelectronics is the first to embed in an IC. Should the Dolby decoder provide only
Left Total/ Right Total (Lt/Rt) signal, an embedded Dolby ProLogic decoder is aimed to
provide the same output quality as with 5.1 inputs.

 New consumer application emergences, in particular the flat screen TV market, bring new
audio challenges to overcome and require more specific dedicated audio compensation
tools such as Smart Volume Control (SVC) compressor/expender on headphone and
loudspeakers, anticlipping, 3-bands parametric and 5-band graphic equalizer for a better
acoustic compensation.

 In addition to the STV83xy family, a complete digital audio (demodulation, sound processor,
audio amplifier) solution for TV can be used thanks to ST digital class D amplifier STA333
family, with additional equalization capability if required.
STMicroelectronics provides a C reference code for the TV controller to facilitate the
integration in the application software.
STV83x7 and STV83x8 are fully hardware and software compatible to answer platform
uniformization strategy.

 To support our customers with an efficient evaluation stage, STMicroelectronics provides an
evaluation bundle with board and software, a comprehensive documentation and application
note.
STV83xy products are available in two (2) packages, LQFP100 and LQFP80 14x14. Both
are pin to pin compatible with the previous product generation.

Applications
Typical applications of the STV83xy TV sound processor family are as follows:
● analog flat panel TV
● digital ready flat panel TV
● integrated digital flat TV
● integrated digital flat TV with integrated hard drive (PVR)
