Video switches route analog signals along paths of
least resistance Analog video is very much alive and well despite the advance of digital video. By
properly using wideband, low-distortion switches and drivers, you can guide signals to
their intended destinations. Various switching configurations provide flexibility in
routing as well as path control.

Design Features
Fight corruption, preserve purity with
analog-signal isolation Analog-signal isolation isn't just for preventing injury and damage from high
voltages. It can dramatically reduce noise and artifacts that corrupt sensitive
measurements.

Home-automation networks mature while the PC
industry chases a new home LAN Two types of networks are headed into the home. Control, or home-automation, network
technology has finally matured enough to promise widespread deployment. Meanwhile, the PC
industry is furiously pursuing new data LANs for the home. IC, card, and system vendors
must choose the right LAN and meld it with the right control network.

Subtleties count in wide-dynamic-range analog
interfaces Transporting high-dynamic-range analog signals from one piece of equipment to another
is not a trivial task. Even subtle design variations can make huge differences in the
equipment's ability to reject interference from the ac power line and other sources when
the equipment connects to a real-world system.

Sniffer probe locates sources of EMI A miniature EMI "sniffer probe" and an oscilloscope can help to locate and
identify magnetic-field sources of EMI. Small size with relatively high sensitivity and
electrostatic shielding enable the probe to provide much more information than other
available probes.

Debugging embedded systems If your µC-based design is short on pins, you can perform diagnostics via only one
pin by implementing a serial condition monitor.

Registered-output FSMs synchronize outputs to
state transitions State machines with both registered next-state transitions and registered
outputs can deliver higher performance, lower power consumption, greater silicon
efficiency, easier modification, and more predictable operation than traditionally coded
alternatives.
