SN65LV1224DBRG4

Overview

The SN65LV1224DBRG4 is a deserializer component from the SN65LV1023/SN65LV1224 chipset, designed for serializing and deserializing data over LVDS differential backplanes. It converts a serial LVDS input stream into ten parallel LVTTL outputs (ROUT0–ROUT9). The device operates with a reference clock frequency ranging from 30 MHz to 66 MHz, supporting payload bandwidths of 300 Mbps to 660 Mbps. It features an internal PLL that requires no external components, synchronization modes for faster lock acquisition, and a lock indicator output. The part is housed in a 28-pin SSOP package and supports industrial temperature operation.

Feature Summary

• Supports rapid synchronization mode using specific SYNC patterns to establish link lock within deterministic timeframes
• Includes a built-in lock indicator output that transitions low when the internal PLL successfully locks onto the embedded clock edge
• Features programmable edge triggering on both transmit and receive clocks to accommodate various system timing requirements
• Provides dedicated power-down and high-impedance modes to reduce supply current during idle periods or hot insertion

Applications

• Serializing and deserializing data over LVDS differential backplanes
• Transmitting and receiving data over unshielded twisted pair (UTP) cables
• Systems requiring fast link initialization via synchronization patterns
• Hot insertion applications where open-loop random-lock synchronization is utilized

Procurement Notes

Verify the exact ordering suffix against the manufacturer's latest Package Option Addendum to confirm packaging details and environmental compliance status. Ensure the selected variant matches the required pin count and thermal characteristics for the target application design.

Selection Notes

Select this deserializer to pair with the SN65LV1023 serializer for complete 10-bit SerDes functionality. Confirm that the system clock frequency falls within the specified 30 MHz to 66 MHz range. Verify that the load capacitance on the parallel outputs does not exceed the recommended limits for the desired clock speed.

Part Context

This component belongs to the SN65LV1023/SN65LV1224 family of 10-bit LVDS serializers and deserializers. It serves as the receiver counterpart to the SN65LV1023 transmitter, forming a complete chipset solution for high-speed parallel-to-serial conversion. The series is characterized for industrial temperature ranges and offers flow-through pinouts for simplified PCB layout.

Replacement Considerations

The SN65LV1224DB is listed as a parameter-equivalent alternative. Verify compatibility regarding package dimensions and electrical specifications before substitution.
