600 MHz, 32 × 32 Buffered Analog Crosspoint Switch
The AD8117/AD8118 are high speed, 32 × 32 analog crosspoint switch matrices. They offer 600 MHz bandwidth and slew rate of 1800 V/μs for high resolution computer graphics (RGB) signal switching. With less than −70 dB of crosstalk and −80 dB isolation (at 5 MHz), the AD8117/AD8118 are useful in many high speed applications. The 0.1 dB flatness greater than 50 MHz makes the AD8117/AD8118 ideal for composite video switching.
The AD8117/AD8118 include 32 independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs so that off-channels present minimal loading to an output bus. The AD8117 has a differential gain of +1, while the AD8118 has a differential gain of +2 for ease of use in back terminated load applications. They operate as fully differential devices or can be configured for single-ended operation. Either a single +5 V supply or dual ±2.5 V supplies can be used, while consuming only 500 mA of idle current with all outputs enabled. The channel switching is performed via a double-buffered, 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 AD8117/AD8118 are packaged in a 304-ball BGA package and are available over the extended industrial temperature range of −40°C to +85°C.
