SN65LV1023ARHBR

Overview

The SN65LV1023ARHBR is a serializer integrated circuit manufactured by Texas Instruments, designed for high-speed data transmission applications. It functions as a 10:1 LVDS serializer, converting parallel LVTTL data inputs into a single serial LVDS output stream. The device supports input clock frequencies ranging from 10 MHz to 66 MHz, resulting in effective serial data rates between 120 Mbps and 792 Mbps. It operates within a supply voltage range of 3.0 V to 3.6 V and is rated for an ambient operating temperature range of -40°C to +85°C. The component is housed in a 28-pin Thin Shrink Small Outline Package (RHB) with a maximum body width of 5.30 mm.

Feature Summary

• Supports rapid synchronization mode using internal SYNC patterns or random data synchronization for flexible system initialization.
• Includes fail-safe biasing on the differential outputs to ensure defined logic states during power-up or low-data-rate conditions.
• Features a dedicated power-down control pin that disables the PLL and places outputs in a high-impedance state for reduced power consumption.

Applications

• High-speed backplane interconnects requiring parallel-to-serial conversion.
• Data acquisition systems utilizing LVDS differential signaling.
• Industrial equipment interfaces demanding robust noise immunity.

Procurement Notes

Verify the specific suffix 'RHBR' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the corresponding deserializer, such as the SN65LV1224B, for complete SerDes link functionality. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning.

Selection Notes

Select this component when a 10-bit parallel interface must be serialized over a single LVDS differential pair. It is suitable for designs requiring operation up to 66 MHz reference clocks. Consider the SN65LV1023ADBR if a 28-pin SSOP package is preferred over the RHB variant. Verify that the system design accommodates the required 3.3V power supply and thermal dissipation capabilities.

Part Context

This part belongs to the SN65LV1023A series of LVDS serializers. It serves as a successor to older National Semiconductor devices like the DS90LV1023E. The device is typically paired with the SN65LV1224B deserializer to form a complete 10-bit SerDes chipset for reliable high-speed data transfer across printed circuit board backplanes.

Replacement Considerations

The SN65LV1023ADBR is a direct pin-compatible alternative offering the same electrical characteristics in a 28-pin SSOP package. For legacy replacements, the MS1023 serializer provides pin-to-pin compatibility with similar functional specifications.
