DS92LV1212AMSAX

Overview

The DS92LV1212AMSAX is a 10-bit Bus LVDS random lock deserializer with embedded clock recovery. It converts serial data streams into parallel outputs at frequencies between 16 MHz and 40 MHz, supporting up to 400 Mbps payload bandwidth. The device operates on a single 3.3 V supply (range 3.0 V to 3.6 V) within an industrial temperature range of -40°C to +85°C. It features a 28-lead SSOP package and includes power-down capabilities to reduce current consumption.

Feature Summary

• Supports random lock synchronization without requiring specific SYNC patterns from the transmitter
• Eliminates multi-channel skew by using a single differential pair for both clock and data transmission
• Provides high impedance receiver inputs when powered off to support hot insertion applications

Applications

• Heavy-loaded differential backplane data transmission
• Point-to-point communication over Unshielded Twisted Pair (UTP) cable
• System integration requiring hot pluggable bus insertion

Procurement Notes

Verify that the component matches the exact suffix AMSAX for the specified package variant. Confirm the manufacturer origin, as the datasheet indicates National Semiconductor design now managed by Texas Instruments. Ensure the operating voltage and temperature ratings align with your system requirements before finalizing orders.

Selection Notes

Select this component when interfacing with the DS92LV1021 serializer chipset. It is suitable for designs needing low power consumption under 300 mW at maximum frequency. Consider footprint compatibility with the DS92LV1210 if space constraints exist in the PCB layout.

Part Context

This device serves as the receiver counterpart to the DS92LV1021 serializer. It functions as part of a chipset designed to transmit 10 bits of parallel LVTTL data over a serial Bus LVDS link. The architecture allows for reduced cable counts and simplified PCB layouts compared to parallel interfaces.

Replacement Considerations

The DS92LV1212A is an upgrade of the DS92LV1212. The DS92LV1210 is noted as footprint compatible but lacks the improved input threshold sensitivity found in the A version.
