SN65LV1023DBRG4

Overview

The SN65LV1023DBRG4 is a serializer designed for the SN65LV1023/SN65LV1224 chipset, operating at parallel word rates from 30 MHz to 66 MHz. It accepts ten LVTTL data inputs (DIN0–DIN9) and converts them into a serial LVDS stream transmitted via differential outputs DO+ and DO-. The device requires a transmit clock (TCLK) within the 30-MHz to 66-MHz range, resulting in serial data rates between 360 Mbps and 792 Mbps. Powered by DVCC and AVCC supplies ranging from 3 V to 3.6 V, it features internal PLLs requiring no external components. The component is housed in a 28-pin SSOP package and supports industrial temperatures from -40°C to 85°C.

Feature Summary

• Supports rapid synchronization using internally generated SYNC patterns for deterministic lock establishment
• Integrates a Phase-Locked Loop (PLL) system that eliminates the need for external timing components
• Provides programmable edge triggering on the reference clock to optimize PCB layout flexibility

Applications

• Serializing parallel data for transmission over LVDS differential backplanes
• High-speed data communication links utilizing unshielded twisted pair (UTP)
• System initialization sequences requiring fast deserializer lock times

Procurement Notes

Verify the specific ordering suffix against current Texas Instruments documentation to confirm package type and environmental compliance. Confirm RoHS status and lead finish details directly with the manufacturer or authorized distributors before procurement. Ensure the design utilizes the correct 28-pin SSOP footprint compatible with the DB package variant.

Selection Notes

Select this serializer when pairing with the SN65LV1224 deserializer for 10-bit parallel-to-serial conversion. Ensure the application requires an LVTTL input interface and LVDS output signaling. Verify that the system clock frequency falls strictly within the 30-MHz to 66-MHz operational range defined in the datasheet specifications.

Part Context

This component functions as the transmitter side of the SN65LV1023A/SN65LV1224B SerDes chipset. It is engineered to complement the SN65LV1224 deserializer, forming a complete solution for transmitting 10-bit parallel words over a single LVDS differential pair. The device maintains pin compatibility with National Semiconductor equivalents while offering industrial temperature qualification.

Replacement Considerations

The SN65LV1023DB is listed as Not Recommended for New Designs (NRND). Designers should evaluate the SN65LV1023ADBR or SN65LV1023ADBRG4 variants for new implementations, ensuring package dimensions and electrical characteristics remain consistent with the original design requirements.
