DS92LV1021AMSA/NOPB

Overview

The DS92LV1021AMSA/NOPB is a 10-bit serializer designed to convert parallel LVCMOS/LVTTL data into a serial Bus LVDS stream. It operates with a transmit clock frequency between 16 MHz and 40 MHz, achieving a payload data rate of up to 400 Mbps. The device utilizes a single differential pair for transmission, embedding clock bits within the data stream to eliminate skew. It features a 28-lead SSOP package and supports supply voltages from 3.0 V to 3.6 V. Key control inputs include programmable edge triggering, synchronization pins, and power-down functionality.

Feature Summary

• Converts 10-bit parallel data into a high-speed serial Bus LVDS stream with embedded clocking
• Eliminates multi-bus skew by transmitting both clock and data over a single differential pair
• Supports flow-through pinout configuration to simplify printed circuit board layout
• Includes programmable edge triggering and dual synchronization inputs for reliable lock establishment

Applications

• Data transmission over differential backplanes
• Serializing data for Unshielded Twisted Pair (UTP) cable connections
• Multi-drop bus architectures requiring low skew and reduced trace counts

Procurement Notes

Verify component authenticity through authorized distributors or TI direct channels. Confirm RoHS compliance status as the standard version is lead-free. Check for moisture sensitivity level ratings prior to soldering. Ensure the specific ordering suffix matches the required packaging quantity and environmental specifications for your assembly process.

Selection Notes

Select this component when a 10-bit parallel interface must be serialized for long-distance or high-noise environments using Bus LVDS standards. It is suitable for designs requiring a 400 Mbps payload rate with a 16 MHz to 40 MHz system clock. Consider the 28-lead SSOP package constraints and ensure compatibility with TI deserializers like the DS92LV1212A for complete link functionality.

Part Context

This part belongs to the DS92LV1021A family of serializers. It serves as an enhanced successor to the original DS92LV1021, offering improved power-up sequences and internal pull-down features. The series is engineered for robust data integrity in industrial and communication systems where signal skew and electromagnetic interference are critical design factors.

Replacement Considerations

The SN65LV1023ADB is documented as a similar replacement option. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
