A 10Gb/s MLSE-based Electronic-Dispersion-Compensation IC with Fast Power-Transient Management for WDM Add/Drop Networks

In this paper, a receiver IC is designed to recover data and clock in OC-192 OADM-based SONET WDM metro and long-haul networks. This is an electrical solution integrated into the receiver IC to address the power-transient problem for OC-192 links. An electrical solution reduces the cost and simplifies the operation. As power-transient management is added to an existing MLSE-based electronic dispersion compensation (EDC) receiver, in this paper, the focus is primarily on the blocks related to the power-transient management functionality. The MLSE receiver is implemented via an AFE IC in a 0.18 mum SiGe BiCMOS process, and a digital (MLSE equalizer) IC in a 0.13 mum 1.2 V CMOS process, with both dies packaged in a 23times17 mm
