DS92LV1021AMSA

Overview

The DS92LV1021AMSA is a 10-bit serializer manufactured by Texas Instruments, designed to convert parallel LVCMOS/LVTTL data into a serial Bus LVDS stream. It operates with a supply voltage of 3V to 3.6V and supports clock frequencies from 16 MHz to 40 MHz. The device features a 28-lead SSOP package and an operating temperature range of -40°C to +85°C. It provides a payload data rate of up to 400 Mbps using embedded clocking within the serial output.

Feature Summary

• Converts 10-bit parallel data into a single differential serial link
• Embeds clock transitions within every 12-bit cycle
• Supports programmable edge triggering for data strobing
• Includes powerdown mode to reduce supply current

Applications

• Backplane data transmission
• Point-to-point cable connections
• Multi-drop bus systems

Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Confirm RoHS compliance status, noting that the standard suffix may differ from lead-free variants. Check for availability in existing stock or lifetime buy programs if required for maintenance.

Selection Notes

Select this serializer when interfacing 10-bit parallel buses to high-speed serial links. Ensure the system clock falls within the 16 MHz to 40 MHz range. Verify compatibility with TI deserializers like the DS92LV1212A for proper synchronization and lock acquisition.

Part Context

This component belongs to the DS92LV1021A family of serializers. It serves as an upgrade to the original DS92LV1021, offering improved power-up sequences and reduced reflections. It is part of Texas Instruments' Bus LVDS interface portfolio.

Replacement Considerations

The SN65LV1023ADB is listed as a similar replacement option. Verify pinout compatibility and electrical specifications before substitution.
