CY7B923-SXCT

Overview

The CY7B923-SXCT is a single-channel HOTLink transmitter manufactured by Infineon Technologies, designed for high-speed serial data transmission. It operates at a fixed supply voltage of 4.5 V and supports a data rate of up to 100 Mbps. The component is housed in a 28-SOIC surface-mount package with a width of 7.50 mm. It functions within an operating temperature range of 0°C to +70°C and features moisture sensitivity level 3 (MSL 3), requiring 168 hours of reflow soldering compliance. This device serves as the transmitting interface for the HOTLink protocol.

Feature Summary

• Single-channel HOTLink transmitter architecture for serial data output
• Surface-mount 28-SOIC package design for automated assembly
• Fixed 4.5 V power supply operation for stable signal integrity

Applications

• Fibre Channel interface implementations
• High-speed serial data link transmitters
• Telecommunications equipment input stages

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as historical data indicates non-compliance for some variants. Ensure storage conditions meet MSL 3 requirements to prevent moisture-induced damage during soldering processes. Validate pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this component when a dedicated HOTLink transmitter is required for Fibre Channel applications. Consider the fixed 4.5 V supply constraint and SOIC-28 footprint limitations. Evaluate thermal management needs for the 0°C to +70°C industrial temperature range. Compare against newer HOTLink II generations if migration from legacy systems is planned, ensuring protocol compatibility.

Part Context

The CY7B923 series belongs to Infineon's HOTLink family of telecommunications interface ICs. These components facilitate serial communication links using proprietary protocols. The SXCT suffix denotes the specific 28-SOIC tape-and-reel packaging variant. This part acts as the transmitter counterpart to receivers like the CY7B924, forming complete serial link pairs for data exchange.
