- Crosspoint switches operate above 500 MHz, providing professional video designers with unparalleled levels of integration and bandwidth.

Norwood, MA (09/06/2006) - About the AD8117/AD8118
Analog Devices 32 × 32 analog crosspoint switches deliver an unmatched combination of integration and speed for high-resolution video applications. The AD8117 and AD8118 achieve bandwidth of more than 500 MHz—65 percent higher than the nearest competitive 32 × 32 arrays—making them the industry’s first single-chip 32 × 32 analog crosspoint switches to achieve the high speeds required to route Quantum Extended Graphics Array (QXGA) video signals without degrading image quality. QXGA is a high-resolution display standard (2048 × 1536 pixels) that enables very fine detail video images in LCD monitors. Without these two new devices, professional video engineers had to use at least eight analog crosspoint switches to achieve a comparable level of video switching performance at QXGA bandwidths.

Unique Architecture Enables Unprecedented Integration and Bandwidth
The unprecedented combination of bandwidth and array size of the AD8117 and AD8118 are achieved through the use of the industry’s first fully-differential analog crosspoint core architecture. This design offers customers greater flexibility by enabling any combination of differential or single-ended inputs and outputs. Superior image fidelity is accomplished with bandwidth of 500 MHz, slew rate of 1800 volts per microsecond, gain flatness of 0.1 dB out to 100 MHz, and crosstalk of –40 dB at 500 MHz.

Low Power Consumption
The AD8117 and AD8118 consume only 2.5 mW per point—50 percent less power per point than competitive QXGA-capable analog crosspoint solutions. The low power consumption cuts system cost by reducing power supply requirements—the devices operate with a single +5 V supply or dual ±2.5 V supplies—eliminating the need for external heat sinks. In addition, the switches consume 200 mA of standby current and 500 mA of quiescent current.

Ease of Use
The analog crosspoint switches can be easily programmed and reprogrammed. Channel switching is performed via a double-buffered, serial digital control—which can accommodate daisy chaining of several devices—or through a parallel control that allows updating of individual outputs without reprogramming the entire array. The AD8117 and AD8118 are differentiated by output gain—one for the AD8117 and two for the AD8118—making them easier to use in back-terminated load applications.

Availability and Pricing
The AD8117 and AD8118 analog crosspoint switches are sampling now, with full production quantities available in the fourth-quarter of 2006. Both switches are available in 304-ball thermally-enhanced BGA (ball grid array) packages and are priced at $295 in 100-piece quantities. The AD8117 and AD8118 are fully specified over the industrial temperature range of –40 degrees C to +85 degrees C.
