DS92LV1021AMSAX

Overview

The DS92LV1021AMSAX/NOPB is a 10-bit serializer that converts 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, supports a supply voltage range of 3.0 V to 3.6 V, and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Converts 10-bit parallel LVCMOS or LVTTL data into a high-speed serial Bus LVDS output stream
• Embeds clock information directly within the data sequence to remove clock-to-data skew
• Includes programmable synchronization patterns and power-down modes for system control

Applications

• Backplane data transmission systems
• Point-to-point connections using Unshielded Twisted Pair (UTP) cables
• Multi-drop bus architectures requiring low pin-count interfaces

Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging rather than tube. Confirm RoHS compliance status as the standard AMSA variant may differ from the NOPB version. Ensure the design accounts for the NRND status if applicable to long-term availability requirements.

Selection Notes

Select this component when a 10-bit parallel interface must be serialized over a single differential pair. Verify that the source clock falls within the 16 MHz to 40 MHz operational range. Ensure the load impedance matches the specified 27 Ohm requirement for optimal signal integrity.

Part Context

This part belongs to the DS92LV1021A family of serializers designed for Bus LVDS applications. It serves as the transmitter counterpart to deserializers like the DS92LV1212A. The device simplifies PCB layout by reducing trace counts compared to parallel interfaces.

Replacement Considerations

The DS92LV1021AMSA is listed as a similar replacement option. Verify electrical compatibility and pinout alignment before substitution.
