AD8116JSTZ

Overview

The AD8116JSTZ is a high-speed 16 × 16 buffered video crosspoint switch matrix manufactured by Analog Devices Inc. It features a –3 dB signal bandwidth exceeding 200 MHz and channel switch times of 60 ns with 0.1% settling. The device provides excellent video performance, including 60 MHz 0.1 dB gain flatness, 0.01% differential gain error, and 0.01° differential phase error at 5 MHz crosstalk levels of –70 dB. It operates on ±5 V supplies while consuming only 90 mA of idle current. The component is housed in a 128-lead LQFP package (14 mm × 14 mm) and is specified over the commercial temperature range of 0 °C to 70°C.

Feature Summary

• Large 16 × 16 high-speed nonblocking switch array controllable via an 80-bit serial word.
• Buffered inputs and 16 individual output amplifiers capable of driving 150 Ω loads.
• Serial data out allows daisy-chaining of multiple devices to create large switch arrays over 256 × 256.
• Output disable feature allows direct connection of multiple device outputs without loading the output bus.

Applications

• Routing of composite video signals (NTSC, PAL, S, SECAM).
• Routing of component video signals (YUV, RGB).
• Video on Demand systems.
• Ultrasound equipment.
• Communication satellites.

Procurement Notes

Verify the specific ordering suffix JSTZ corresponds to the lead-free 128-lead LQFP package variant when sourcing. Confirm that the supply voltage requirements match the ±5 V specification for both analog and digital sections. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS input structures.

Selection Notes

Select this component for applications requiring dense routing of high-speed analog or digital video signals within a single package. Consider the power dissipation limits and thermal management requirements associated with the 128-lead plastic LQFP package. Evaluate the need for daisy-chaining capabilities if larger switching matrices beyond 16 × 16 are required for the system design.

Part Context

The AD8116 belongs to Analog Devices' family of high-speed video crosspoint switches. It serves as a building block for creating larger nonblocking or blocking crosspoint arrays. The device integrates 256 switch points, offering significant area and power savings compared to using smaller discrete switching elements or lower-density ICs for complex signal routing tasks.

Replacement Considerations

Public confirmed substitute part numbers include AD8116JST and AD8116. These variants share the same functional description as a 200 MHz, 16 x 16 Buffered Video Crosspoint Switch. Verify package compatibility and environmental specifications before substitution.

FAQ

How is the power-on reset function implemented?

A 0.1 μF capacitor connected from the RESET pin to ground holds the signal low after power application, ensuring all outputs are disabled initially.

Can multiple AD8116 devices be chained together?

Yes, the DATA OUT pin can be directly connected to the DATA IN pin of a follow-on AD8116 to create larger switch arrays.

What is the maximum junction temperature for this device?

The maximum safe junction temperature for the plastic encapsulated device is approximately 150 °C, determined by the glass transition temperature of the plastic.
