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

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
The AD8175 (G=+2) and AD8176 (G=+4) triple 16x9 crosspoint switches deliver an industry-best bandwidth of 500MHz, which is more than 60% faster than the nearest competitor, while offering twice the functionality.
The switches feature a slew rate of 1800V/us to support UXGA or Ultra Extended Graphics Array, a high monitor resolution of 1600 x 1200 pixels, which is quadruple the default resolution of SVGA (800 x 600), as well as QXGA or Quad Extended Graphics Array, a superior resolution of 2048 x 1536.
These devices also support sync on common-mode and sync on colour operation.

The ADF9010 integrates a high-performance transmitter quadrature modulator with an integer-N synthesiser and on-chip low-phase-noise voltage-controlled oscillator.
Demodulator and amp cut receiver complexity
Combined two-chip solution can reduce the active component count by 60% within a radio design, providing considerable board area and bill of material savings.
The AD8175/6 can be applied both differentially and single-ended.
The new switches operate on a +/-2.5 or +5V power supply and consume only 3.5W.
Their high level of integration, advanced architecture, and pin-out configuration simplify board layout and system design, while reducing cost.
The AD8175 and AD8176 triple 16x9 crosspoint switches are sampling now and will be available in full production quantities in April and July 2007, respectively.
The AD8175/6 are available in a 676-lead PBGA (plastic ball grid array) package over the extended industrial temperature range of -40 to +85C and are priced at US $95 per unit in 100-unit quantities.
The AD814x family of high-speed differential amplifiers is the industry's first line of triple differential drivers and receivers to achieve full-power bandwidth of 550MHz, or greater, which is more than twice the bandwidth of the nearest competitor.
The wide bandwidth of the differential amplifiers complements the AD8175 switch by fully preserving the resolution of component video when sending and receiving signals across multi-stage video distribution systems.
The ability to easily send and receive RGB and sync signals over Cat5 cable is integrated on one chip, enabling video distribution systems to maximise resolution at the lowest possible cost.
The AD8145/6/7/8 differential amplifiers are sampling now.
The AD8145 receiver is fully released to production, and the AD8146/7/8 drivers will be available in full production quantities in April 2007.
The AD8145/6/7/8 are available in space-saving LFCSP (lead-frame chip-scale package) packages and are priced between US $2.89 and $3.09 per unit in 1000-unit quantities.
