AD8107ASTZ

Overview

The AD8107ASTZ is a high-speed, nonblocking video crosspoint switch featuring a 16 × 5 matrix with an internal gain of two. It operates on ±5 V supplies and consumes 30 mA of idle current. The device provides a −3 dB bandwidth exceeding 260 MHz and a slew rate of 500 V/μs. It includes buffered inputs and five output amplifiers capable of driving 150 Ω loads. Key performance metrics include 0.02% differential gain error, 0.02° differential phase error, and −78 dB all-hostile crosstalk at 5 MHz. The component is housed in an 80-lead LQFP package and supports operation from −40°C to +85°C.

Feature Summary

• Integrated gain-of-two output buffers for direct video line driving
• Parallel control interface allowing individual output updates without full array reprogramming
• Output disable capability for bus paralleling and multi-device expansion
• Asynchronous reset pin for immediate disabling of all outputs

Applications

• Routing composite video signals (NTSC, PAL, S, SECAM)
• Switching component video formats (YUV, RGB)
• Handling compressed video standards (MPEG, Wavelet)
• Processing 3-level digital video (HDB3)

Procurement Notes

Verify the specific suffix ASTZ corresponds to the industrial temperature range and lead-free packaging configuration. Confirm that the 80-lead LQFP footprint matches the target PCB design. Ensure supply voltages are strictly maintained within the ±4.5 V to ±5.5 V operational limits to prevent damage.

Selection Notes

Select the AD8107ASTZ when a voltage gain of two is required at the output stage. The AD8106 variant offers unity gain and higher disabled output impedance, making it suitable for different array topologies. Consider the 16 × 5 architecture constraints when designing larger nonblocking matrices requiring wire-OR connections.

Part Context

This component belongs to the Analog Devices AD8106/AD8107 family of buffered video crosspoint switches. It shares a common core architecture with the AD8106, differing primarily in the analog feedback network which sets the gain. It serves as a building block for constructing larger custom crosspoint arrays alongside devices like the AD8110 and AD8114.

Replacement Considerations

The AD8106ASTZ is the pin-compatible alternative offering unity gain instead of gain of two. For larger matrix requirements, consider the AD8110 or AD8114 series.
