SN65LV1224DBR

Overview

The SN65LV1224DBR is a deserializer from the SN65LV1023/SN65LV1224 chipset, designed for transmitting and receiving serial data over LVDS differential backplanes. It operates at clock speeds from 30 MHz to 66 MHz, supporting serial data rates between 360 Mbps and 792 Mbps with a payload throughput of up to 660 Mbps. The device accepts a single LVDS serial input and outputs ten parallel LVTTL/LVCMOS data lines. It features an internal PLL requiring no external components, synchronization modes for faster lock acquisition, and a low-power shutdown state. The component is housed in a 28-pin SSOP package and is qualified for industrial temperatures ranging from -40°C to 85°C.

Feature Summary

• Supports rapid synchronization via specific SYNC patterns or random-lock synchronization for open-loop applications.
• Integrates an on-chip PLL that eliminates the need for external timing components.
• Provides a LOCK indicator output to monitor deserializer synchronization status.
• Includes programmable power-down and high-impedance states to reduce system power consumption.

Applications

• Serializing and deserializing data across LVDS differential backplanes.
• High-speed data transmission over unshielded twisted pair (UTP) cables.
• Systems requiring hot insertion capabilities into running backplanes.

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current Package Option Addendum to confirm lead finish and environmental classification. Confirm the production status as Not Recommended for New Designs (NRND) before initiating new procurement contracts. Ensure compatibility with existing PCB footprints for the 28-pin SSOP package.

Selection Notes

Select this component when a 10-bit parallel-to-serial conversion is required using LVDS signaling. Ensure the system design accommodates the separate analog (AVCC) and digital (DVCC) power supply requirements. Verify that the application can provide the necessary REFCLK signal for the deserializer's internal PLL locking mechanism.

Part Context

This part functions as the receiver counterpart to the SN65LV1023 serializer within the same chipset family. Both devices share identical pinouts and operate together to facilitate high-speed data transfer. The SN65LV1224B variant represents an updated version of the original SN65LV1224, offering improved electrical characteristics while maintaining functional compatibility.
