Modulation Flexibility

- ATSC 8-VSB demodulation

- 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

- Autonomous operation - Internal DSP firmware execution eliminates

the need for supervision and operation by the system host

Excellent VSB Performance

- Superior 8-VSB multi-path performance with equalizer coverage

of –34us to +78us.

- 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

- Excellent doppler ghosts rejection

- Fast channel auto search by carrier lock of +/-400KHz and NTSC

channel detection

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

- 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

FDC Demodulator (OOB)

- 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)

Sound stereo decoder

- US BTSC mono, stereo and SAP (DBX) decoding

- Korea A2 FM mono, stereo and bilingual decoding

- FM radio stereo decoding

- IIS server/client with output clock of 48KHz, 44.1KHz, and 32KHz

Advanced System Functions

- 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

- 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

Standard 14x14 mm 100pin LQFP package
