DS92LV1224TMSAX/NOPB

Overview

The DS92LV1224TMSAX/NOPB is a 30-66 MHz, 10-bit Bus LVDS deserializer manufactured by Texas Instruments. It converts a serial data stream into a 10-bit parallel bus with a throughput of 300 to 660 Mb/s. The device operates on a single 3.3 V supply (3.0 V to 3.6 V) and consumes less than 300 mW at 66 MHz. It features a 28-lead SSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed unidirectional serial data transmission over FR-4 backplanes and balanced copper cables.
• Features robust Bus LVDS serial data transmission with embedded clock for exceptional noise immunity.
• Includes a programmable edge trigger on the recovered clock for flexible timing control.

Applications

• High-speed data transmission across printed circuit board backplanes
• Serial-to-parallel conversion in balanced copper cable systems
• Point-to-point or multi-drop interconnect applications

Procurement Notes

Verify component authenticity through authorized channels. Confirm the specific ordering suffix matches the required package and temperature grade. Check for RoHS compliance documentation. Ensure the part number corresponds to the exact revision required for your design specifications.

Selection Notes

Select this component when a 1:10 deserialization ratio is required for 10-bit wide data buses. Ensure the system utilizes a compatible serializer, such as the DS92LV1023E, to form a complete chipset. Verify that the application environment stays within the specified -40°C to +85°C temperature limits.

Part Context

This device belongs to the DS92LV1224 series of LVDS interface integrated circuits. It is designed to work in conjunction with compatible serializers to simplify PCB layout by narrowing data paths. The series focuses on reducing PCB size and layer count while maintaining high-speed signal integrity.

Replacement Considerations

The SN65LV1224BDBG4 is a documented alternative within the same product family. Verify pinout compatibility and electrical characteristics before substitution. Ensure the replacement meets the specific frequency and voltage requirements of the original design.

FAQ

How does the DS92LV1224 handle loss of lock during data transmission?

If the Deserializer loses lock, the LOCK output goes high and outputs enter TRI-STATE. The system can detect this state and pulse the Serializer's SYNC inputs to resynchronize the devices.

What is the purpose of the RCLK_R/F input pin?

The RCLK_R/F pin selects the active edge of the recovered clock used to strobe the ROUT data. A high level selects the rising edge, while a low level selects the falling edge.

Can the DS92LV1224 support hot insertion?

Yes, the device supports hot insertion into a running backplane using its random lock capability, provided proper grounding and power sequencing rules are followed.
