The RTL2840 is a complete QAM demodulator that supports all QAM modes from QPSK to 1024 QAM, as well as a wide range of symbol rates (from less than 1Msps to more than 7Msps). It fully is compatible with the ETS 300 429 DVB-C specification. A high-resolution ADC and PLL are embedded to directly sample and process IF (Intermediate Frequency) signals. The powerful carrier recovery, timing recovery, and adaptive equalizer allow for highly efficient QAM signal reception.
With on-chip FEC (Forward Error Correction) and a BER (Bit-Error Rate) tester, the RTL2840 reports receiving status and signaling quality information. A built-in automatic re-acquisition function permits use of an extremely simple driver. An MPEG2 transport stream interface supports both serial and parallel modes. The RTL2840 can be flexibly configured by the built-in IIC interface to process signals in various conditions. The RTL2840 is ideal for DVB-C applications and provides high performance and stability.
