DS92LV1023TMSA/NOPB

Overview

The DS92LV1023TMSA/NOPB is a 40-66 MHz single 10:1 serializer designed for high-speed unidirectional serial data transmission. It converts a 10-bit wide parallel LVCMOS/LVTTL data bus into a single high-speed Bus LVDS serial data stream with an embedded clock, achieving throughput rates of 400-660 Mbps. The device operates on a 3.0V to 3.6V supply voltage and features low power consumption, typically under 250 mW at 66 MHz. It includes programmable edge triggering, flow-through pinout for simplified PCB layout, and high impedance outputs when powered off. The component is housed in a 28-lead SSOP package.

Feature Summary

• Converts 10-bit parallel LVCMOS/LVTTL data into a single serial Bus LVDS stream with embedded clock
• Supports data rates from 400 to 660 Mbps over FR-4 backplanes and balanced copper cables
• Features flow-through pinout architecture to simplify printed circuit board design
• Includes programmable rising or falling edge clock triggering and low power shutdown mode

Applications

• High-speed unidirectional serial data transmission over FR-4 printed circuit board backplanes
• Data communication links using balanced copper cables
• Parallel-to-serial conversion interfaces requiring low electromagnetic interference

Procurement Notes

Verify the specific ordering suffix to confirm packaging and environmental compliance. The TMSA/NOPB variant indicates a lead-free, RoHS-compliant product in a 28-lead SSOP package. Confirm availability status as this part may be designated as Not Recommended for New Designs (NRND) or Life Buy depending on current inventory channels. Ensure compatibility with existing deserializer components such as the DS92LV1224 for complete chipset functionality.

Selection Notes

Select this serializer when a single differential pair is required to replace multiple parallel data lines, thereby reducing PCB layer count and cable complexity. Ensure the system clock frequency falls within the 40 MHz to 66 MHz range. Verify that the load resistance matches the specified 27 Ohms for proper Bus LVDS signal integrity. Consider the 28-lead SSOP package dimensions if space constraints are critical for the application design.

Part Context

This component belongs to the Texas Instruments Bus LVDS family, originally developed by National Semiconductor before its acquisition by TI. It is specifically engineered to work in conjunction with compatible deserializers like the DS92LV1224. The series addresses the need for robust, noise-immune serial communication in industrial and computing environments where parallel buses become impractical due to skew and crosstalk issues.

Replacement Considerations

Direct substitutes include other 10-bit Bus LVDS serializers from the same family. Check for updated revisions or alternative packages if the 28-SSOP form factor is no longer suitable. Verify electrical compatibility with the intended deserializer to ensure synchronized PLL locking and correct data rate support.
