SN65LV1212DBG4

Overview

The SN65LV1212DBG4 is a deserializer component within the Texas Instruments SN65LV1021/SN65LV1212 chipset, designed for 10-bit serial data transmission over LVDS differential backplanes. It operates with system clock frequencies ranging from 10 MHz to 40 MHz, supporting serial data rates between 120 Mbps and 480 Mbps. The device accepts a reference clock (REFCLK) and recovers embedded clock information from the incoming LVDS signal to output parallel LVTTL data. It features a LOCK indicator pin that signals successful PLL synchronization. The component is housed in a 28-pin SSOP package and supports industrial temperature operation from -40°C to +85°C.

Feature Summary

• Supports rapid synchronization via internal SYNC patterns or random-lock synchronization for open-loop applications.
• Includes a LOCK output pin to indicate when the internal PLL has successfully synchronized to the incoming data stream.
• Features programmable edge trigger selection for both transmit and receive clocks to facilitate flexible PCB layout.

Applications

• Serializing and deserializing 10-bit parallel data across LVDS differential backplanes
• High-speed data transmission systems requiring low power consumption and minimal external components
• Applications necessitating hot insertion capabilities into running backplanes

Procurement Notes

Verify the specific ordering suffix 'G4' against current manufacturer documentation to confirm lead-free compliance and RoHS status. Confirm the active production status, as datasheets may list this variant as NRND. Ensure the 28-pin SSOP package dimensions match the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select the SN65LV1212DBG4 when paired with the SN65LV1021 serializer for 10:1 data reduction. Ensure the design accommodates separate AVCC and DVCC power supplies within the 3V to 3.6V range. Verify that the REFCLK input frequency matches the required TCLK frequency of the serializer to maintain proper data throughput and lock stability.

Part Context

This component belongs to the SN65LV1021/SN65LV1212 family of 10-MHz to 40-MHz LVDS serializers and deserializers. It serves as the receiver counterpart to the SN65LV1021 serializer, forming a complete serdes chipset. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing variations within the standard SSOP package line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Texas Instruments documentation for potential pin-compatible alternatives or updated series replacements if this part is marked NRND.
