SCAN921025HSM-NS

Overview

The SCAN921025HSM-NS is a high-speed serializer manufactured by National Semiconductor, operating within the SCAN921025H series. It converts parallel data into a serial stream at rates up to 800 Mb/s. The device accepts 10-bit parallel inputs via LVCMOS or LVTTL interfaces and outputs a single differential signal using LVDS technology. It functions with a supply voltage between 3 V and 3.6 V, drawing approximately 105 mA. Designed for robust industrial environments, it supports an extended temperature range from -40°C to +125°C and is housed in a 49-pin FBGA package.

Feature Summary

• Converts 10-bit parallel digital signals into a high-speed serial output stream
• Supports low-voltage CMOS and TTL input logic levels for flexible system integration
• Utilizes Low Voltage Differential Signaling (LVDS) for reliable long-distance transmission
• Operates reliably across extreme ambient temperatures suitable for harsh industrial conditions

Applications

• High-speed video signal transmission systems
• Industrial automation control networks
• Medical imaging equipment data links
• Test and measurement instrument interfaces

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance requirements as original variants may not meet current environmental standards. Validate pinout compatibility during replacement planning. Ensure proper ESD handling procedures are followed during installation. Review datasheet specifications for thermal management needs.

Selection Notes

Select this component when interfacing parallel logic sources with differential transmission lines. Ensure the host system operates within the specified 3V to 3.6V power range. Verify that the receiving end utilizes a compatible LVDS deserializer. Consider the 49-pin FBGA footprint constraints during PCB layout design. Evaluate thermal dissipation capabilities for enclosed industrial enclosures.

Part Context

This part belongs to the SCAN921025H family of high-speed analog interface chips originally developed by National Semiconductor. The series was designed to extend the capabilities of existing LVDS product lines. Texas Instruments acquired National Semiconductor's semiconductor business, leading to the rebranding of these components under the TI portfolio while maintaining the original model numbering conventions.
