Abstract :
This complete BiCMOS read channel IC in 0.8 /spl mu/m BiCMOS achieves 30O Mb/s maximum data rate. The majority of the signal processing in this IC is carried out in the analog sampled-data domain. The key circuit block in the channel is an 8-state time interleaved EPR4 Viterbi trellis detector. The BER measurements show ideal performance gain over a PR4 channel.
