SPECIFICATION DVBS TUNER 1.SCOPE MDVBS2-6613 Revision:1.0 The MDVBS2-6613 supports QPSK in DIRECTV and DVB-S legacy transmission (1 to 45 Mbauds), plus 8PSK in DVB-S2 transmissions (1 to 45 Mbauds).

DVB-S2 demodulation uses robust symbols probust by the transmission to ensure efficient carrier tracking.

Carrier and timing recovery loops are fully digital and tunable.

Carrier-to-noise ratio (CNR) calculation and constellation display are also supported.
