DTV Demodulator IC
Product Brief
Key Features
Modulation Flexibility
FDC Demodulator (OOB)
- ATSC 8-VSB demodulation
- OpenCable SCTE DVS-178 & 167 QPSK demodulation
- 8 taps adaptive equalizer
- On-chip frequency synthesizer provides LO for FDC
down-conversion
- Direct Cable Card interface compliant with SCTE 28 2001
(DVS-295)
- OpenCable, ANSI/SCTE DVS-031, ITU-T J.83 Annex B and
DOCSIS compliant 64/256 QAM demodulation
- OOB downstream demodulation, complies with SCTE DVS-178
and DVS-167 specifications
- Audio stereo decoding: US BTSC audio mono, stereo and SAP
decoding (DBX), Korea A2 FM mono, stereo and bilingual,
with IIS output
Sound stereo decoder
- Autonomous operation - Internal DSP firmware execution eliminates
the need for supervision and operation by the system host
- US BTSC mono, stereo and SAP (DBX) decoding
- Korea A2 FM mono, stereo and bilingual decoding
- FM radio stereo decoding
Excellent VSB Performance
- IIS server/client with output clock of 48KHz, 44.1KHz, and 32KHz
- Superior 8-VSB multi-path performance with equalizer coverage
of –34us to +78us.
Advanced System Functions
- Superior VSB indoor reception using enhanced equalization and
synchronization algorithms, based on training signal and data-aided
equalization, enables Brazil and other 0dB ghosts reception
- Adaptive control loops according to channel conditions for fast
channel acquisition and optimal tracking
- Accepts 44MHz or low-IF from the tuner eliminating external
base-band demodulation
- Separate RF and IF AGC PWM outputs
- Parallel and serial MPEG2 transport outputs
- All digital recovery loops
- Excellent doppler ghosts rejection
- Fast channel auto search by carrier lock of +/-400KHz and NTSC
channel detection
- Firmware loading IIC serial bus from host upon initialization
- Integrated IIC switch for isolation of the tuner IIC port during
normal reception modes
- Via IIC, the Cascade2 reports FEC statistics, receiver status,
and channel data such as S/N ratio, equalizer taps, carrier offset,
and more
- EIA/CEA-909 Mode A Smart Antenna Interface
- Internal mux for serial output of decrypted TS from POD
Excellent QAM Performance
- ANSI/SCTE DVS-031, ITU-T J.83 Annex B 64/256QAM,
5.059641/5.360537MHz symbol rate.
- Integrated 32Kbytes deinterleaver RAM for DI modes
up to I=128 J=4.
- 84 taps equalization range: 36 FFE and 48 DFE for superior
cable micro-reflection rejection
Standard 14x14 mm 100pin LQFP package
- Superior phase noise rejection
- Superior burst noise and combined distortion rejection
- Superior AM noise rejection
- Fast channel auto search based on auto 64/256QAM detection and
wide carrier acquisition range of +/-500KHz
