SCAN921821TSM

Overview

The SCAN921821TSM is a dual 18-bit serializer manufactured by Texas Instruments, designed for high-speed serial data transmission. It operates with an LVDS input interface and provides a single LVDS output channel. The device supports a maximum data rate of 2.376 Gb/s and functions within a supply voltage range of 3.15 V to 3.45 V. It is housed in a 100-pin NFBGA package and is rated for commercial operation between -40°C and +85°C. Key features include integrated pre-emphasis capabilities, IEEE 1149.1 (JTAG) support, and at-speed built-in self-test (BIST) functionality.

Feature Summary

• Dual 18-bit serialization architecture with integrated pre-emphasis for signal integrity enhancement
• Supports IEEE 1149.1 (JTAG) standard for boundary scan testing and diagnostics
• Includes at-speed built-in self-test (BIST) capability for comprehensive functional verification

Applications

• High-speed digital video transmission systems
• FPGA external serial interface implementations
• Industrial imaging and sensor data acquisition links

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package variant and temperature rating. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the supplier provides valid traceability documentation for the component batch.

Selection Notes

Select this component when a dual 18-bit serializer with LVDS I/O is required for data rates up to 2.376 Gb/s. Consider the NFBGA-100 package constraints and the 3.15 V to 3.45 V power supply requirements during PCB design. Evaluate the need for JTAG and BIST features if system-level testing and diagnostic coverage are critical design parameters.

Part Context

This part belongs to the SCAN921821 series of serializers from Texas Instruments. It is categorized under Serializers & Deserializers (SerDes) within the Interface ICs product family. The device is specifically engineered for applications requiring reliable high-speed parallel-to-serial conversion with advanced testing capabilities.

Replacement Considerations

The SCAN921821TSM/NOPB is a verified equivalent part number offering identical electrical specifications and functionality. Verify pinout compatibility and package dimensions before substitution.
