• In this paper, a transceiver VLSI architecture is proposed for high speed digital CATV modems, which can perform both the QAM and the VSB transmissions [1], [2]. The proposed architecture of all-digital dual-mode QAM/VSB receiver consists of digital AGC, digital demodulator, fractionally spaced blind equalizer and DFE, digital carrier recovery, and symbol timing recovery. Finite word-length simulation results show that the proposed architecture can achieve an SNR 29dB for both the 64-QAM mode and 8-VSB mode when the 10bit ADC input signal SNR is 36dB, and there are ±6kHz of carrier frequency offset, ± 110ppm of symbol rate offset, and -82 dBc carrier phasejitter at 10kHz away from the nominal carrier frequency.
