260 MHz, 16 x 8 Buffered Video Crosspoint Switch (Gain=2)
The AD8110 and AD8111 are high-speed 16 × 8 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 (@ 5 MHz), the AD8110/AD8111 are useful in many high-speed applications. The differential gain and differential phase of better than 0.02% and 0.02° respectively, along with 0.1 dB flatness out to 60 MHz, make the AD8110/AD8111 ideal for video signal switching.
The AD8110 and AD8111 include eight 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 AD8110 has a gain of +1, while the AD8111 offers a gain of +2. They operate on voltage supplies of ±5 V while consuming only 50 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 AD8110/AD8111 is packaged in an 80-lead LQFP package and is available over the extended industrial temperature range of –40°C to +85°C.
- Routing of high-speed signals including:
- Composite video (NTSC, PAL, S, SECAM)
- Component video (YUV, RGB)
- Compressed video (MPEG, Wavelet)
- 3-level digital video (HDB3)
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
