SN65LV1023DBR

Overview

The SN65LV1023DBR is a 10-bit serializer manufactured by Texas Instruments, designed for high-speed data transmission over LVDS differential backplanes. It accepts parallel LVTTL inputs and converts them into a serial LVDS stream at rates up to 792 Mbps, corresponding to parallel clock frequencies of 30 MHz to 66 MHz. The device operates on a single 3V to 3.6V supply and features an internal PLL requiring no external components. Key control pins include DEN for output enablement and PWRDN for low-power shutdown. It is housed in a 28-pin SSOP package.

Feature Summary

• Supports rapid synchronization via internally generated SYNC patterns for deterministic lock establishment.
• Enables open-loop operation with random-lock synchronization for hot insertion applications.
• Integrates programmable edge triggering for flexible clock strobing configurations.

Applications

• High-speed data transmission over LVDS differential backplanes
• Serializing parallel LVTTL data streams for long-distance communication
• Hot insertion compatible serial link interfaces

Procurement Notes

Verify the specific ordering suffix 'DBR' against current manufacturer documentation to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints for the 28-SSOP form factor. Cross-reference RoHS compliance status and lead finish details directly with the supplier's latest product data sheet prior to final procurement decisions.

Selection Notes

Select this component when a 10-bit parallel-to-serial conversion is required for LVDS transmission. It pairs with the SN65LV1224B deserializer to form a complete SerDes chipset. Consider the 30 MHz to 66 MHz operating range and the need for internal PLL integration without external components when evaluating system requirements.

Part Context

This part belongs to the SN65LV1023/SN65LV1224 family of 10:1 LVDS serializers and deserializers. It serves as the transmitter counterpart to the SN65LV1224B receiver. The series supports payload bandwidths from 30 MHz to 66 MHz and is characterized for industrial temperature ranges, providing a cost-effective solution for embedded serial links.

Replacement Considerations

The SN65LV1023DBG4 is a pin-compatible alternative within the same package family. Verify if the 'G4' suffix indicates a specific manufacturing update or material change before substitution. No other direct functional replacements are documented in the provided source material.

FAQ

How does the SN65LV1023 handle synchronization?

It supports two modes: Rapid Synchronization using internally generated SYNC patterns for deterministic lock times, and Random-Lock Synchronization which allows the paired deserializer to lock to random data streams without special patterns.

What is the maximum useful data rate?

At a 66 MHz TCLK frequency, the useful data rate is 660 Mbps (10 bits x 66 MHz), while the total serial transmission rate including overhead is 792 Mbps.

How is the device powered down?

Driving the PWRDN pin low turns off the PLL and places the outputs into a high-impedance state, reducing supply current to the milliampere range. Driving it high exits power-down mode.
