SN65LV1224BRHBT

Overview

The SN65LV1224BRHBT is a low-voltage differential signaling (LVDS) deserializer manufactured by Texas Instruments. It converts a single LVDS serial data stream into ten parallel LVTTL outputs, functioning as the receiver component in a 10-bit SerDes pair alongside the SN65LV1023A serializer. The device supports data rates from 100 Mbps to 660 Mbps and operates on a single 3.0 V to 3.6 V power supply. It features an integrated phase-locked loop (PLL) for clock recovery and includes synchronization modes for rapid link initialization. The component is housed in a 28-pin TSSOP package and is rated for operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-performance PLL for robust clock recovery from the incoming LVDS data stream without requiring a separate reference clock input.
• Supports multiple synchronization methods, including fast SYNC mode using specific sample patterns and random data synchronization for open-loop applications.
• Provides fail-safe biasing circuitry at the LVDS inputs to ensure defined output states during power-up or when the transmitter is inactive.
• Includes a dedicated LOCK status output pin that indicates when the internal PLL has successfully acquired the embedded clock signal.

Applications

• High-speed parallel bus extension over LVDS differential backplanes in industrial systems.
• Video display interfaces requiring transmission of parallel RGB data streams via serial links.
• Test and measurement equipment utilizing high-bandwidth data acquisition architectures.

Procurement Notes

Verify the exact suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure compatibility with the paired serializer, such as the SN65LV1023A, regarding voltage levels and synchronization protocols. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process.

Selection Notes

Select this component when a 1:10 deserialization ratio is required for LVDS applications up to 660 Mbps. It is suitable for designs needing integrated clock recovery and fail-safe features. Consider the SN65LV1224BDBR variant if a SSOP package is preferred over the RHBT TSSOP form factor.

Part Context

This part belongs to the SN65LV1224 family of LVDS interface devices. It serves as the complementary receiver to the SN65LV1023A serializer, forming a complete 10-bit SerDes solution. The family is designed to replace older ECL-based parallel buses with lower voltage differential signaling for improved noise immunity and reduced power consumption.

Replacement Considerations

The SN65LV1224BDBR is a parameter-equivalent alternative offering the same functionality in a 28-SSOP package instead of the TSSOP format.
