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 mm ) 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
