Analog video distribution solutions support 500MHz bandwidth

Analog Devices Inc. (ADI) has introduced the first combination of analog crosspoint switches and driver/receiver amplifiers that support bandwidths up to 500MHz for analog video. Low implementation costs and the ability to deliver high-resolution content across distance continue to make analog video the preferred method for distributing full-motion video to LCD and plasma displays used in retail outlets, public spaces and keyboard, video and mouse (KVM) systems.

Industry-best bandwidth
The AD8175 (G=+2) and AD8176 (G=+4) triple 16x9 crosspoint switches promise an industry-best bandwidth of 500MHz, which is more than 60 percent faster than the nearest competitor, while offering twice the functionality. The switches feature a slew rate of 1,800V/?s to support UXGA or Ultra eXtended Graphics Array, a high monitor resolution of 1600-by-1200pixels, which is quadruple the default resolution of SVGA (800-by-600pixels), as well as QXGA or Quad eXtended Graphics Array, a superior resolution of 2048-by-1536pixels. These devices also support sync on common-mode and sync on color operation. The AD8175/6 can be applied both differentially and single-ended. The new switches operate on a ±±2.5V or +5V power supply and consume 3.5W. Their high level of integration, advanced architecture and pin-out configuration simplify board layout and system design, while reducing cost.

Availability, pricing
The AD8175 and AD8176 triple 16x9 crosspoint switches are sampling today and will be available in full production quantities in April and July 2007, respectively. The AD8175/6 are available in a 676-lead PBGA package over the extended industrial temperature range of 40&176;C to 85&176;C and are priced at $95 per unit in 100-unit quantities.

The AD8145/6/7/8 differential amplifiers are sampling today. The AD8145 receiver is fully released to production, and the AD8146/7/8 drivers will be in full production in April 2007. The AD8145/6/7/8 are available in space-saving LFCSP packages and are priced between $2.89 and $3.09 per unit in 1,000-unit quantities.
