AD8110ASTZ

Overview

The AD8110ASTZ is a high-speed 16 × 8 buffered video crosspoint switch manufactured by Analog Devices Inc. It features a –3 dB bandwidth of 260 MHz and operates on ±5 V supplies with a typical idle current of 50 mA. The device provides G = +1 voltage gain and includes eight independent output buffers capable of driving 150 Ω loads. Key performance metrics include a slew rate of 500 V/µs, crosstalk of –78 dB at 5 MHz, and differential gain/phase errors better than 0.02% and 0.02°, respectively. It supports serial or parallel control interfaces and is housed in an 80-lead LQFP package.

Feature Summary

• High-speed nonblocking switch array with integrated buffered outputs
• Supports both serial daisy-chaining and parallel programming modes
• Low power consumption with dedicated output disable capability
• Includes reset pin for power-on initialization

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 signals (HDB3)

Procurement Notes

Verify the specific suffix ASTZ to confirm the industrial temperature range and RoHS compliance status. Confirm availability through authorized distributors as supply levels may fluctuate. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS input structures.

Selection Notes

Select the AD8110ASTZ when a G = +1 configuration is required; the AD8111 variant offers G = +2. Consider the 80-lead LQFP package constraints for PCB layout. Verify that the system can accommodate the ±5 V dual supply requirement and that the 40-bit serial shift register timing meets the controller's clock speed capabilities.

Part Context

This component belongs to the AD811x family of video crosspoint switches, designed for professional broadcast and video routing applications. It shares architectural similarities with the AD8108/AD8109 series but expands the matrix size to 16 inputs by 8 outputs. The device is part of Analog Devices' portfolio of high-performance signal switching solutions.

Replacement Considerations

The AD8111ASTZ is a pin-compatible alternative offering G = +2 gain instead of G = +1. For smaller matrices, the AD8108/AD8109 series provides 8x8 configurations. Larger arrays can be constructed using the AD8116. Verify gain requirements and channel count before substituting.
