LT1675CMS8-1#PBF

Video Processing Overview

The LT1675CMS8-1#PBF is a single-channel RGB multiplexer with an integrated amplifier, housed in an 8-lead MSOP package. It features a 250MHz small-signal bandwidth and an 1100V/µs slew rate for high-speed signal processing. The device includes one SPDT switch and one current feedback amplifier configured for a fixed gain of 2. It operates on dual supplies ranging from ±4V to ±6V, drawing 11mA during normal operation and reducing to 33µA when disabled.

Video Processing Feature Summary

• Integrates a single SPDT switch and a current feedback amplifier optimized for direct cable driving
• Features break-before-make switching logic to minimize input feedthrough and crosstalk
• Includes internal gain setting to eliminate external resistors and reduce PCB footprint
• Supports chip disable functionality to significantly reduce power consumption

Video Processing Applications

• Pixel switching in fast workstation graphics systems
• RGB video routing and signal multiplexing
• Driving double-terminated 50Ω or 75Ω coaxial cables
• High-speed signal processing applications requiring low transient glitches

Video Processing Procurement Notes

Verify the specific suffix CMS8-1#PBF against the manufacturer's official ordering guide to confirm the MSOP package type and lead-free status. Ensure the selected variant matches the required operating temperature range and pinout configuration for your circuit design before finalizing procurement.

Video Processing Selection Notes

Select this component for applications requiring a single-channel video switch with integrated amplification. The fixed gain of 2 is designed specifically for driving double-terminated cables. Consider the MSOP package size if board space is limited compared to larger SSOP or SO-8 alternatives within the same family.

Video Processing Part Context

This part belongs to the LT1675/LT1675-1 series of high-speed RGB multiplexers. While the standard LT1675 provides three channels for full RGB routing, the LT1675-1 variant offers a single channel suitable for monochrome or composite video signals. The MSOP package provides a compact solution for space-constrained designs.

Video Processing FAQ

How does the LT1675-1 handle switching transients?

It utilizes fast current steering break-before-make SPDT switches that minimize switching glitches, resulting in a small 50mV peak-to-peak transient lasting approximately 5ns.

What is the purpose of the ENABLE pin?

Grounding the ENABLE pin allows normal operation. Taking it high or leaving it open shuts down the device, reducing supply current to near zero.
