Silicon timing clocks are getting sophisticated
Oct 1, 2006
Ashok Bindra, Editorial Director Whether it is a microprocessor-based control circuitry, RF transceiver for wireless communications, or a linecard for optical networks, clocks are needed as timing circuits to perform functions like synchronization, distribution, control and protection. They are critical components when it comes to overall system performance. Over time, these simple discrete components have become quite sophisticated....
Addressing the new challenges of MIMO wireless LAN manufacturing test
Oct 1, 2006
By Ewan Shepherd Using MIMO architectures, it is possible to extend the data rate or range of
WLAN components. However, there are multiple transmitters and receivers in
this architecture with stringent specifications, which complicates the design and
manufacture of these systems. Nevertheless, new equipment and techniques
can keep the testing costs within the range of that for 802.11a/g systems....
