Description
The CE6355 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 CE6355 has a wide frequency capture range able to
automatically compensate for the combined offset intro-
duced by the tuner xtal and broadcaster triple frequency
offsets.
An on-chip state machine controls all acquisition and tracking
operations of the CE6355 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 infor-
mation, including input signal power level, signal-to-noise
ratio, pre-Viterbi BER, post-Viterbi BER, and the uncor-
rectable block counts. The error rate monitoring periods are
programmable over a wide range.
The device is packaged in a 7 x 7 mm 64-pin LQFP and is
very low power.

... The first step of the demodulation process is to convert this signal to a complex (in-phase and quadrature) signal in baseband. A correction for spectral inversion is implemented during this conversion process. Note also that the CE6355 has control mechanisms to search automatically for an unknown spectral inversion status. 12 CE6355 Intel Corporation ...

... MPEG data can be output in parallel or serial mode. The output clock frequency is automatically chosen to present the MPEG data as uniformly spaced as possible to the transport processor. This frequency depends on the guard ratio, constellation, hierarchy and code rate.
