DS92LV1021AMSAX/NOPB

Overview

The DS92LV1021AMSAX/NOPB is a 10-bit Bus LVDS serializer manufactured by Texas Instruments. It converts parallel LVCMOS/LVTTL data into a serial high-speed stream with an embedded clock, supporting input clock frequencies from 16 MHz to 40 MHz. The device operates on a single 3.0 V to 3.6 V supply and features a 28-lead SSOP package. It provides a maximum serial bandwidth of 400 Mbps at the upper clock limit, utilizing a single differential pair for transmission. Key electrical parameters include a typical output differential voltage of 270 mV and a power-down current of 300 μA.

Feature Summary

• Converts 10-bit parallel data into a serial Bus LVDS stream with embedded clock bits
• Supports programmable edge triggering and synchronization modes for reliable data transfer
• Includes low-power sleep mode and tri-state capability for system management

Applications

• Data transmission over differential backplanes
• Point-to-point connections via Unshielded Twisted Pair (UTP) cable
• Multi-drop bus configurations requiring phase locking

Procurement Notes

Verify component authenticity through authorized channels as this part is designated LIFEBUY status. Confirm that the specific ordering suffix matches the required packaging quantity and lead finish specifications. Ensure compliance with RoHS directives and check for any applicable environmental declarations before finalizing procurement orders.

Selection Notes

Select this serializer when interfacing 10-bit parallel buses to LVDS links within the 16 MHz to 40 MHz frequency range. Ensure the design accommodates the 28-lead SSOP footprint and thermal dissipation requirements. Verify compatibility with TI deserializers such as the DS92LV1212A for synchronized operation.

Part Context

This component belongs to the DS92LV1021 family of Bus LVDS serializers. It serves as an enhanced successor to the DS92LV1021, offering improved flexibility regarding clock application timing and reduced reflections. The series is designed for cost-effective reduction of trace counts in high-speed digital interfaces.

Replacement Considerations

The DS92LV1021AMSA is the non-RoHS equivalent of this part number. Designers should verify pinout compatibility if substituting between these variants.
