SCAN921226HSM

Overview

The SCAN921226HSM is a high-temperature serial deserializer manufactured by Texas Instruments, formerly National Semiconductor. It operates within a supply voltage range of 3 V to 3.6 V, with a typical operating voltage of 3.3 V and a maximum power dissipation of 1.47 W. The device supports data rates up to 800 Mb/s (20–80 MHz clock) and accepts BLVDS input signals. It features a 10-bit parallel output interface and is housed in a 49-ball FBGA package. Designed for harsh environments, it functions between -40°C and +125°C, drawing approximately 120 mA during operation.

Feature Summary

• Supports high-speed data transmission up to 800 Mb/s using differential signaling
• Engineered for reliable operation in extreme temperature environments up to 125°C
• Converts serial differential inputs to 10-bit parallel digital outputs

Applications

• Automotive systems requiring robust interface solutions in high-heat zones
• Industrial factory automation equipment operating in harsh conditions
• High-temperature sensor data acquisition interfaces

Procurement Notes

This component carries an NRND status, indicating it is not recommended for new designs. Verify current availability through authorized distributors, as stock levels may be limited. Ensure compliance with humidity sensitivity requirements during handling and storage to prevent damage before assembly.

Selection Notes

Select this deserializer when pairing with the corresponding SCAN921025H serializer for point-to-point links. Confirm that the system environment exceeds standard commercial temperature limits. Verify that BLVDS input compatibility matches the source driver specifications before integration into the design.

Part Context

Part of the SCAN921226H series, this device complements the SCAN921025H serializer. Together, they form a complete LVDS serializing/deserializing chipset designed for long-distance, high-speed data transfer in demanding applications where standard CMOS or TTL interfaces are insufficient due to noise or distance constraints.

Replacement Considerations

No direct public substitute part numbers are confirmed. Due to the NRND status, alternative components must be evaluated for pin compatibility, electrical characteristics, and thermal performance. Consult manufacturer documentation for potential obsolescence management strategies.
