AD8115: Low Cost 225 MHz 16 x 16 Crosspoint Switch, G=+2
Product Description
The AD8114/AD81151 are high speed 16 x 16 video crosspoint switch matrices. They offer a –3 dB signal bandwidth greater than 200 MHz, and channel switch times of less than 50 ns with 1% settling. With –70 dB of crosstalk and –90 dB isolation (@ 5 MHz), the AD8114/AD8115 are useful in many high speed applications. The differential gain and differential phase of better than 0.05% and 0.05° respectively, along with 0.1 dB flatness out to 25 MHz while driving a 75 Ω back-terminated load, make the AD8114/AD8115 ideal for all types of signal switching.
AD8114/AD8115 include 16 independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs so that off channels do not load the output bus. The AD8114 has a gain of 1, while the AD8115 offers a gain of 2. They operate on voltage supplies of ±5 V while consuming only 70 mA of idle current. The channel switching is performed via a serial digital control (which can accommodate daisy-chaining of several devices) or via a parallel control, allowing updating of an individual output without reprogramming the entire array.
The AD8114/AD8115 is packaged in 100-lead LQFP package and is available over the extended industrial temperature range of –40°C to +85°C.
An evaluation board is available for this product and may be ordered using the following product number: AD8114-EVAL and AD8115-EVAL. Schematic and layout for this evaluation board is contained in the product datasheet.
