MDVBS2-6613

CO M TECH TECHNO LO G Y CO . , LTD. 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. 2.GENERAL SPECIFICATIONS 2-1. 2-2. 2-3. 2-4. 2-5. 2-6. 2-7. 2-8.
