SN65LV1212DB

Overview

The SN65LV1212DB is a deserializer component within the Texas Instruments SN65LV1021/SN65LV1212 chipset, designed for 10-bit serializer/deserializer applications. It operates with system clock frequencies ranging from 10 MHz to 40 MHz, supporting serial data rates between 100 Mbps and 400 Mbps. The device accepts LVDS differential inputs and provides parallel LVTTL outputs. It functions over an ambient temperature range of -40°C to +85°C and utilizes a 28-pin SSOP package.

Feature Summary

• Supports synchronization modes including rapid synchronization via internal SYNC patterns and random-lock synchronization for open-loop applications.
• Includes a LOCK indicator output that transitions low when the internal PLL successfully locks onto the embedded clock edge.
• Features programmable edge trigger selection on both transmit and receive clocks to accommodate various timing requirements.

Applications

• Transmission of serial data over LVDS differential backplanes
• Data transmission over unshielded twisted pair (UTP) cables
• Parallel-to-serial and serial-to-parallel conversion in high-speed interface systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm availability status. The SN65LV1212DB variant is classified as NRND, indicating it is not recommended for new designs. Confirm lead finish and moisture sensitivity levels prior to procurement to ensure compatibility with assembly processes.

Selection Notes

Select this component when interfacing with the SN65LV1021 serializer for 10-bit data paths requiring clock speeds up to 40 MHz. Ensure the design accommodates the separate analog and digital power supplies (AVCC and DVCC). Verify that the application supports the required initialization and synchronization sequences before deployment.

Part Context

This part belongs to the SN65LV1xxx series of LVDS interface integrated circuits manufactured by Texas Instruments. It serves as the receiver counterpart to the SN65LV1021 serializer, forming a complete 10:1 serdes solution. The family is engineered for high-speed data transmission using low-voltage differential signaling standards.

Replacement Considerations

The SN65LV1212DBG4 is a pin-compatible RoHS-compliant version of this device. Designers should evaluate alternative components if new production is required due to the NRND status.
