Modulator/demodulator for fixed satellite networks

Features

• IF sub-sampling or I/Q baseband interface;
• Variable ADC width support;
• Single external clock source required;
• Single external analogue loop for AGC;
• Fully digital and automatic frequency recovery - no VCXO or AFC required;
• Single external analogue loop for automatic timing recovery – 1 external VCXO required. PWM or DAC control;
• Fully digital matched channel filter for robust performance in the presence of ACI;
• Linear demodulator algorithm ensures rapid convergence of AGC, PLL and equalizer sub-systems;
• DVB-S2 support: QPSK, 8PSK/16APSK/32APSK.
• Number of synthesis options to optimise speed (and therefore symbol rate) vs. area;
• Software programmable symbol demapping;
• Implementation loss of <0.5dB.
