MTV600

One-chip Receiver for DVB-S/DVB-S2/ABS-S/DSS/ISDB-S

• Description

  The MTV600 is a highly integrated single chip zero-IF tuner for digital broadcasting system-satellite (DVB-S, DVB-S2, ABS-S, DSS and ISDB-S). It operates from 950 to 2150 MHz for full DVB-S and DSS standard. It includes an LNA/AGC and direct conversion down mixers and PLL/VCO. On-chip low phase noise VCO, which eliminates external tank circuits, generates In-phase and Quadrature-phase local oscillation signal for the entire frequency range. For optimized performance with variable symbol rate, baseband channel select filters are fully programmable and their cutoff frequency is digitally tuned to 4 MHz to 40 MHz. MTV600 also includes high dynamic range operation.

  The MTV600 exhibits low power consumption, while providing competitive performance. The power down function reduces the standby mode current consumption for power hungry system. The Zero-IF IC has on-chip voltage regulator for single power supply application. Using small QFN package, MTV600 is the best solution for highly integrated satellite TV system and portable application where low power consumption is required. MTV600 has an industry standard I2C serial bus interface. Primary application of MTV600 is the direct broadcast satellite (DBS).
