FEATURES
• Different modulation schemes: 4, 16, 32, 64 and 256-QAM
• Digital demodulator and square root raised cosine Nyquist filter with roll-off of 15% or 20%
• High performance adaptive equalizer (no training sequence needed)
• Digital detectors for generation of required control voltages for carrier recovery, clock recovery and AGC
• Digital-to-analog converters and operational amplifiers allowing high flexibility for selection of the (PLL) loop time constants
• High maximum symbol rate (rs) of 7 Msymbols/s
• Input format: Straight binary or 2’s complement (up to 9 bits, TTL compatible)
• Output format: 8-bit wide bus (CMOS compatible)
• I2C-bus interface to initialize and monitor the demodulator. When no I2C-bus usage; 64-QAM, 20% roll-off factor in default mode
• 5 V peripheral and analog supply voltage
• 3.3 V core supply voltage
• Boundary scan test.

APPLICATION
