DS92LV1212AMSAX/NOPB

Overview

The DS92LV1212AMSAX/NOPB is a 10-bit Bus LVDS deserializer designed to receive serial data streams and transform them into a parallel data bus. It operates with clock frequencies from 16 MHz to 40 MHz, supporting up to 400 Mbps payload bandwidth. The device features embedded clock recovery without requiring synchronization patterns, enabling random lock capabilities for hot insertion applications. It utilizes a single differential pair input (RI+, RI-) and provides ten CMOS/LVTTL outputs (ROUT0-ROUT9) alongside a recovered clock output (RCLK). The component supports power-down modes to reduce supply current and includes failsafe biasing options.

Feature Summary

• Supports random lock initialization and resynchronization without SYNC patterns
• Eliminates multi-channel skew by using a single differential pair for serial data and clock
• Provides high impedance on receiver inputs when powered off
• Includes programmable edge trigger selection for the recovered clock

Applications

• Hot insertion into running backplanes
• Open-loop applications requiring open-loop operation
• Point-to-point transmission over PCB traces or twisted pair cables

Procurement Notes

Verify that the ordering suffix 'A' corresponds to the DS92LV1212A revision rather than the original DS92LV1212. Confirm the package type matches the MSA28 footprint requirements. Ensure the design accounts for the specific failsafe biasing resistor values if the receiver inputs are left undriven to prevent noise-induced false locking.

Selection Notes

Select this component when a 10-bit parallel interface is required with minimal trace count. It is suitable for systems needing low power consumption under 300mW at 40MHz. Consider the improved threshold sensitivity of +/-50mV compared to previous generations. Verify compatibility with the paired DS92LV1021 serializer for chipset integration.

Part Context

The DS92LV1212AMSAX/NOPB is an upgraded version of the DS92LV1212. It maintains all functional features while offering enhanced input threshold sensitivity. It is part of a chipset family that includes the DS92LV1021 serializer. The device is housed in a small 28-lead SSOP package, facilitating easier PCB layout through its flow-through pinout configuration.

Replacement Considerations

The DS92LV1212AMSA serves as the direct predecessor model. Both devices share identical functionality and pinouts. Designers should verify that the specific application does not require the distinct improvements in threshold sensitivity provided by the DS92LV1212A revision.
