Fighting Jitter in Fibre-Channel Designs
By Bob Rumer
Routing multiple serial signals can be a daunting task during the development of fibre channel systems. Fortunately, digital
repeaters and retimer ICs can clean up signals and counteract jitter in order to ensure spec compliance.
Enabling Fast Wireless Networks with OFDM
By Jim Geier
Spread spectrum modulation has been the basis for many proprietary and IEEE 802.11-based wireless LANs (WLANs). Through the use of frequency hopping and direct sequence, these WLANs provide data rates from 1 to 11 Mbps. In addition, new activity with
