STV0297E
QAM demodulator IC with A/D converter
Data Brief
Features
■ Decodes ITU-T J.83-Annexes A/C
and DVB-C bit streams
■ Processes Japanese transport stream
multiplex frame (TSMF)
■ High-performance integrated A/D converter
suitable for direct IF architecture in all QAM
(quadrature amplitude modulation) modes
■ Supports 16, 32, 64, 128 and 256 point
constellations
■ Small footprint package: (10 x 10 mm²)
■ Very low power consumption
■ Full digital demodulation
■ Variable symbol rates
■ Front derotator for better low symbol rate
performance and relaxed tuner constraints
■ Integrated matched filtering
■ Robust integrated adaptive pre and post
equalizer
■ On-chip FEC A/C with ability to bypass
individual blocks
■ 10 programmable GPIO
■ Two AGC outputs suitable for delayed AGC
applications (sigma-delta outputs)
■ Integrated signal quality monitors, plus lock
indicator and interrupt function mapped to
GPIO pin
■ Improved signal acquisition
■ System clock generated on-chip from quartz
crystal
■ Low frequency crystal operations 4, 16, 25 -
30 MHz
■ 4 I²C addresses
■ Easy control and monitoring via 2-wire fast I2C
bus
TQFP64 (10 x 10 x 1.40 mm)
■ Additional I²C bus (I²C repeater) dedicated to
tuner control for minimum tuner disturbance
■ Programmable clock derived from system
clock and available for external use
■ Parallel and serial output interfaces, with DVB
common interface support
■ On chip voltage regulator
■ CMOS technology, 1.0 V operation
Applications
■ Japan, Europe, Asia cable set-top boxes
■ Cable modems
■ Cable ready TV
■ Cable PC card
■ Cable network module
