Overview
The DS15BR400TVSX/NOPB is a four-channel LVDS buffer and repeater manufactured by Texas Instruments. It supports data rates up to 2 Gb/s with low jitter characteristics from DC to the maximum speed. The device accepts CML, LVDS, or LVPECL input signals and provides LVDS outputs. It operates on a single 3.3 V power supply with a voltage range of 3.0 V to 3.6 V. Key electrical parameters include a propagation delay of 2 ns and an operating current of 215 mA. The component functions within a temperature range of -40°C to +85°C and is housed in a 48-pin TQFP package.
Feature Summary
- Provides four independent channels for buffering and repeating LVDS signals
- Supports multiple input standards including CML, LVDS, and LVPECL
- Designed for low jitter performance across DC to 2 Gb/s bandwidth
Applications
- High-speed serial data transmission systems
- LVDS signal distribution networks
- Data communication equipment requiring signal regeneration
Procurement Notes
Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the specific suffix TVSX indicates the tape and reel packaging variant. Ensure the NOPB suffix confirms lead-free and RoHS compliance status before procurement.
Selection Notes
Select this component when interfacing between different logic families such as CML sources and LVDS loads. It is suitable for applications requiring signal integrity maintenance over long traces. Consider the 48-pin TQFP package constraints for PCB layout and thermal management requirements.
Part Context
This part belongs to the DS15BR400 series of high-speed interface devices. It serves as a bridge for converting and boosting Low Voltage Differential Signaling (LVDS) streams. The device is often evaluated using the dedicated DS15BR400EVK/NOPB evaluation kit provided by the manufacturer.
Replacement Considerations
The DS15BR400TSQ/NOPB is a qualified automotive-grade alternative within the same family. Verify pin compatibility and operational temperature ranges when substituting.
