SCAN90004TVS/NOPB

Signal Buffers, Repeaters, Splitters Overview

The SCAN90004TVS/NOPB is a four-channel LVDS buffer and repeater manufactured by Texas Instruments. It supports a maximum data rate of 1.5 Gbps per channel with configurable pre-emphasis to mitigate ISI jitter on lossy backplanes and cables. The device accepts differential inputs compatible with LVDS, CML, and LVPECL standards, while providing LVDS outputs. It features integrated 100Ω input and output termination resistors. Operating conditions include a supply voltage range of 3.15V to 3.45V and an industrial temperature range from -40°C to +85°C. The component is housed in a 48-pin TQFP package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Configurable pre-emphasis functionality to drive lossy transmission media
• Integrated IEEE 1149.1 JTAG and limited IEEE 1149.6 testability support
• On-chip 100Ω differential input and output termination resistors
• Hardware power-down mode for low-power standby operation

Signal Buffers, Repeaters, Splitters Applications

• Point-to-point backplane signal buffering and re-driving
• Long-distance cable transmission signal boosting
• Interfacing between FPGA/ASIC LVDS I/O and high-speed receivers

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm environmental compliance and lead-free status. Confirm that the active status aligns with long-term availability requirements for the target design lifecycle. Ensure the TQFP-48 package footprint matches the PCB layout constraints.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when point-to-point LVDS signaling requires signal regeneration over lossy interconnects. The inclusion of IEEE 1149.6 support makes it suitable for designs requiring boundary scan testing of high-speed differential links. Verify that the single-ended LVTTL control interface meets system logic levels.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the SCAN90004 family of LVDS interface devices. It serves as a specialized buffer/repeater variant distinct from standard drivers or receivers. The device was originally developed under National Semiconductor before being integrated into the Texas Instruments product portfolio.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS90LV004TVS/NOPB is a documented non-JTAG version within the same family. Designers requiring identical electrical performance without test circuitry may consider this alternative.
