2.
Features
s 4,16, 32, 64, 128 and 256 QAM demodulator (ITU-T J.83 annex A-B and C compatible)
s High performance for 256 QAM especially for direct IF applications
s On-chip 10-bit ADC
s On-chip PLL for crystal frequency multiplication (typically 16 MHz crystal)
s Digital down conversion
s Programmable half Nyquist lter (roll off = 0.12, 0.13, 0.15 and 0.18)
s Two PWM AGC outputs with programmable take-over point (for tuner and down
converter control)
s Clock timing recovery, with programmable second order loop lter
s Variable symbol rate capability from SACLK/64 to SACLK/4 (with low sampling clock:
SACLK = 36 MHz maximum) or from SACLK/128 to SACLK/8 (with high sampling
clock: SACLK = 72 MHz maximum)
s Programmable anti-aliasing lters
s Full digital carrier recovery loop
s Carrier acquisition range up to 9 % of symbol rate
s Integrated adaptive equalizer (linear transversal equalizer or decision feedback
equalizer)
s DVB compatible differential decoding and mapping
s On chip DVB-C full compliant FEC decoder (de-interleaver, Reed-Solomon decoder
and de-scrambler)
s On chip MCNS full compliant FEC decoder (trellis demodulator, de-randomizer,
de-interleaver and Reed-Solomon decoder)
s Multiple TS JQAM lter
s Parallel and serial transport stream interface simultaneously
s I2C-bus interface, for easy control
