AD8104:  600 MHz, 32 × 16 Buffered Analog Crosspoint Switch

Product Description

The AD8104/AD8105 are high speed, 32 × 16 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 −90 dB isolation (@ 5 MHz), the AD8104/AD8105 are useful in many high speed applications. The 0.1 dB flatness, which is greater than 50 MHz, makes the AD8104/AD8105 ideal for composite video switching.

The AD8104/AD8105 include 16 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 AD8104 has a differential gain of +1, while the AD8105 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 340 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 AD8104/AD8105 are packaged in a 304-ball BGA package and are available over the extended industrial temperature range of −40°C to +85°C.
