AD8106 260 MHz, 16 × 5 Buffered Video Crosspoint Switches
Product Details
The AD8106 and AD8107 are high speed, 16 × 5 video crosspoint switch matrices. They offer a −3 dB signal bandwidth greater than 260 MHz, and channel switch times of less than 25 ns with 1% settling. With −78 dB of crosstalk and −97 dB isolation (at 5 MHz), the AD8106/AD8107 are useful in many high speed applications. The differential gain and differential phase of greater than 0.02% and 0.02° respectively, along with 0.1 dB flatness out to 60 MHz, make the AD8106/AD8107 ideal for video signal switching.
The AD8106 and AD8107 include five independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs, preventing off channels from loading the output bus. The AD8106 has a gain of 1, while the AD8107 offers a gain of 2. Both operate on voltage supplies of ±5 V while consuming only 30 mA of idle current. The channel switching is performed via a parallel control, allowing updating of an individual output without reprogramming the entire array.
The AD8106/AD8107 are offered in an 80-lead LQFP and are available over the extended industrial temperature range of −40°C to +85°C.
