AD8116XST

製品説明
仕様・特性

a PRODUCT DESCRIPTION The AD8116 is a high speed 16 × 16 video crosspoint switch matrix. It offers a –3 dB signal bandwidth greater than 200 MHz and channel switch times of 60 ns with 0.1% settling. With –70 dB of crosstalk and –105 dB of isolation (@ 5 MHz), the AD8116 is useful in many high speed applications. The differential gain and differential phase errors of better than 0.01% and 0.01°, respectively, along with 0.1 dB flatness out to 60 MHz make the AD8116 ideal for video signal switching. The AD8116 includes 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. It operates on voltage AD8116 CLK CLK DATA IN DATA OUT 80-BIT SHIFT REG.

Frequency Response supplies of ± 5 V while consuming only 90 mA of idle current. The channel switching is performed via a serial digital control that can accommodate “daisy chaining” of several devices. REV. B The AD8116 is packaged in a 128-lead LQFP package occupying only 0.36 square inches, and is specified over the commercial temperature range of 0°C to 70°C.
