•SPDC210A is a state-of-the-art DVB-T Terrestrial COFDM (Coded Orthogonal Frequency Division Multiplex) Demodulator chip. SPDC210A Demodulator matches to Sunplus backend MPEG decoder SPHE1002A to offer a DVB-T turnkey solution. The turnkey solution delivers the advanced features and outstanding performance index. It is in mass production now.

•SPDC210A builds on either 2K or 8K modes with 6, 7 or 8 MHz channels and supports QPSK/16QAM/64QAM reception. SPDC210A integrates a high performance 10-bit ADC converter. The sampling rates can be generated from different clock source, which may come from crystal, or external clocks. Smart FFT design highly reduces power consumption, which can be less than half of traditional FFT, and still has good signal handling performance. SPDC210A power dissipation is low to around 210mW, which can be an industry benchmark.

•FEC implementation associated with BER, can indicate capture range for BER calculation. Serial or Parallel MPEG transport stream output can be connected to all commercial MPEG-2 processor chips. Dual AGC can be used for RF and IF AGC control. I2C-like is used for programming command interface.
