An ac-coupled burst-mode receiver (B-Rx) for 10-Gbit/s class PON systems that uses a novel baseline-wander common-mode-rejection (BLW-CMR) technique and an inverted distortion technique is proposed and demonstrated. The realization of 10-Gbit/s class PON systems requires the development of a B-Rx with high sensitivity, a wide dynamic range, and a fast response for handling the burst-mode data. The...
In this paper, a burst-mode CDR circuit is presented that achieves output-data- jitter reduction of 3dB at jitter frequency of 1 GHz, synchronization to the input data within 14 bits of the burst input, and tolerance to pulse-width distortion (PWD) of +0.22/-0.32UI at 10.3125 Gb/s operation. These characteristics are provided by a CDR architecture with jitter-reduction and PWD-compensation circuits.
We have developed an ac-coupled burst-mode transceiver using baseline-wander common-mode-rejection techniques for 10-Gbit/s-class PON systems. The fabricated transceiver achieved 10.3125-Gbit/s operation with an ultra-fast response.
The CDR circuit is fabricated in 0.25 mum SiGe BiCMOS technology. The low-speed digital blocks, such as the frequency detector, the up/down counter, the modulator, and the dither generator, are developed using CMOS transistors. The LPF used in the DAC is integrated in the chip. Two power supplies, 3.3 V for bipolar transistors and 1.8 V for CMOS, are used. PONs such as 10G-EPON systems require a burst-mode...
