SN65LV1023DB

Overview

The SN65LV1023DB is a serializer component manufactured by Texas Instruments, designed for high-speed data transmission over LVDS differential backplanes. It accepts ten parallel LVTTL inputs and converts them into a single serial LVDS output stream at rates up to 660 Mbps. The device operates within a supply voltage range of 3V to 3.6V and supports ambient temperatures from -40°C to 85°C. Packaged in a 28-pin SSOP (DB) format, it integrates an internal PLL requiring no external components. Key control pins include DEN for output enablement and PWRDN for low-power shutdown modes.

Feature Summary

• Integrates a Phase-Locked Loop (PLL) without the need for external passive components
• Supports rapid synchronization via internally generated SYNC patterns for deterministic lock times
• Provides programmable edge triggering on both transmit and receive clocks
• Includes dedicated LOCK indicator output to monitor deserializer synchronization status

Applications

• High-speed data transmission over LVDS differential backplanes
• Parallel-to-serial conversion for embedded systems
• Industrial temperature qualified communication links

Procurement Notes

Verify the specific ordering suffix 'DB' corresponds to the 28-pin SSOP package configuration. Confirm RoHS compliance status as the datasheet indicates a lifetime-buy period for this specific part number. Ensure the design accounts for the specified operating temperature range and power-down current requirements during system integration.

Selection Notes

Select the SN65LV1023DB when a 10-bit parallel-to-serial conversion with LVDS output is required. Pair this serializer with the SN65LV1224B deserializer to form a complete chipset. Verify that the application requires LVTTL input levels and that the 28-pin SSOP footprint fits the PCB layout constraints.

Part Context

This component belongs to the SN65LV1023/SN65LV1224 family of 10:1 LVDS serializers and deserializers. It functions as the transmitter side of the pair, handling the serialization of parallel data streams. The device is characterized for industrial temperature ranges and is pin-compatible with certain National Semiconductor equivalents.
