- Full featured evaluation board for the AD8115
- Uses USB Board Z with PIC18F4550 for the digital control
- ±5 V operation
The AD8115 is a high speed 16 × 16 video crosspoint switch matrices. It offers a −3 dB signal bandwidth greater than 200 MHz and channel switch times of less than 50 ns with 1% settling. The AD8115 includes 16 independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs to prevent off channels from loading the output bus. The AD8115 has a gain of +2. They both operate on voltage supplies of ±5 V while consuming only 70 mA of idle current. Channel switching is performed via a serial digital control that can accommodate the daisy-chaining of several devices or via a parallel control to allow updating of an individual output without reprogramming the entire array.
The AD8115 is available in a 100-lead LQFP over the extended industrial temperature range of −40°C to +85°C. Some applications of these analog crosspoint switches are routing of high speed signals including video (NTSC, PAL, S-video, SECAM, YUV, RGB), compressed video, three-level digital video, data communications, and telecommunications.
The AD8112, AD8113, AD8114/AD8115, and ADV3205 are all pin-compatible with each other and are available in the same 100-lead LQFP, which can be evaluated on a single board.
