LT1675CS8-1

Video Processing Overview

The LT1675CS8-1 is a single-channel RGB video multiplexer with an integrated current feedback amplifier in an 8-lead SOIC package. It features a 250MHz small-signal bandwidth and an 1100V/µs slew rate for high-speed pixel switching. The device operates on ±4V to ±6V supplies, drawing 11mA typically at ±5V. It includes a fixed gain of 2 configured internally, eliminating external resistors. The output drives double-terminated 50Ω or 75Ω cables directly.

Video Processing Feature Summary

• Integrates SPDT switch and current feedback amplifier for direct cable driving
• Fixed internal gain of 2 eliminates external setting resistors
• Break-before-make switching minimizes signal coupling and glitches
• Expandable architecture allows input expansion via ENABLE pin control

Video Processing Applications

• High-speed workstation graphics routing
• Pixel switching in video processing systems
• Direct drive of 50Ω or 75Ω coaxial cables
• Video sync and composite blanking insertion

Video Processing Procurement Notes

Verify the specific suffix CS8-1#PBF indicates the lead-free SOIC-8 variant. Confirm supply voltage requirements match the ±4V to ±6V range. Ensure thermal management accounts for the specified junction temperature limits. Check for RoHS compliance status if required by assembly standards.

Video Processing Selection Notes

Select this part for single-channel applications requiring high bandwidth and fast switching speeds. The SOIC-8 package offers a compact footprint compared to larger multiplexers. Consider the LT1675CGN for triple-channel RGB needs. Verify that the fixed gain of 2 aligns with the system's cable termination requirements.

Video Processing Part Context

This component belongs to the LT1675 family of high-speed video multiplexers. It utilizes Linear Technology’s proprietary high-speed bipolar process to achieve performance exceeding 100MHz pixel switching. The series is designed to replace discrete solutions using separate switches and amplifiers, offering reduced board space and power consumption.

Video Processing Replacement Considerations

LT1675CGN provides triple-channel functionality in a 16-pin SSOP package.
