SN65LV1224DB

Overview

The SN65LV1224DB is a deserializer from the Texas Instruments SN65LV1023/SN65LV1224 chipset, designed for transmitting and receiving serial data over LVDS differential backplanes. It converts serialized LVDS signals into parallel LVTTL outputs at equivalent word rates of 30 MHz to 66 MHz. The device operates with a supply voltage range of 3 V to 3.6 V and supports an operating temperature range of -40°C to 85°C. It features a built-in PLL requiring no external components, synchronization modes for faster lock, and a lock indicator output.

Feature Summary

• Supports rapid synchronization mode using internally generated SYNC patterns for deterministic lock times
• Enables open-loop random-lock synchronization for hot insertion applications without special SYNC patterns
• Includes a dedicated LOCK output pin that transitions low when the internal PLL successfully locks onto the embedded clock edge
• Provides programmable edge triggering on both transmit and receive clocks via TCLK_R/F and RCLK_R/F inputs

Applications

• Serializing and deserializing data over LVDS differential backplanes
• Hot insertion systems requiring open-loop synchronization capabilities
• Parallel-to-serial and serial-to-parallel conversion in industrial environments

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the 28-pin SSOP designation. Ensure environmental compliance aligns with project requirements. Review current production status as availability may be limited due to lifecycle announcements.

Selection Notes

Select this component when interfacing with the SN65LV1023 serializer for complete 10-bit SerDes functionality. Ensure system clock frequencies remain within the specified 30 MHz to 66 MHz range. Verify power supply stability between 3 V and 3.6 V. Consider thermal management for operation up to 85°C ambient temperature.

Part Context

This device belongs to the SN65LV1023/SN65LV1224 family of LVDS serializers and deserializers. It serves as the receiver counterpart to the SN65LV1023 serializer, forming a complete 10-bit SerDes chipset. The family is characterized for industrial temperature ranges and offers pin-compatible alternatives to previous generations.

Replacement Considerations

SN65LV1224BDBR is a tape-and-reel variant of the same functional device. SN65LV1224BMDBREP is an extended temperature version (-55°C to 125°C). Verify package compatibility and temperature ratings before substitution.
