SN65LVDS93DGGG4

Overview

The SN65LVDS93DGGG4 is a Texas Instruments LVDS serializer IC featuring 28 single-ended LVTTL inputs and four LVDS differential outputs. It operates within a supply voltage range of 3 V to 3.6 V and supports data rates up to 1904 Mb/s. The device utilizes a 56-pin TSSOP package with dimensions of 14 mm x 6.1 mm x 1.15 mm. It functions across an industrial temperature range from -40°C to +85°C. This component implements a 28:4 channel compression architecture for high-speed point-to-point subsystem communication.

Feature Summary

• Integrates four 7-bit parallel-load serial output shift registers and a 7x clock synthesizer for efficient data serialization.
• Supports selectable rising or falling edge clock triggering via the CLKSEL pin for flexible system integration.
• Provides high electrostatic discharge (ESD) protection on bus pins, rated at 6 kV human body model (HBM).
• Delivers low electromagnetic interference (EMI) characteristics suitable for demanding electronic environments.

Applications

• High-speed point-to-point subsystem communication in complex electronic systems.
• Flat panel display interfaces requiring significant data channel compression.
• Applications necessitating robust ESD protection and low EMI emissions.

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status against current manufacturer documentation. Confirm the 56-TSSOP package outline matches the target PCB footprint requirements. Ensure the operating voltage range of 3 V to 3.6 V aligns with the system power design. Check moisture sensitivity level (MSL 2) handling procedures if storage conditions exceed specified limits.

Selection Notes

Select this component when 28 parallel LVTTL inputs must be serialized into four LVDS channels. The 1904 Mb/s maximum data rate defines the bandwidth capability for the application. Consider the 56-pin TSSOP package constraints for board space. Verify that the -40°C to +85°C temperature range meets the environmental operating conditions.

Part Context

This part belongs to the SN65LVDS93 series of LVDS serializers. It is functionally related to deserializers like the SN65LVDS94 for complete link solutions. The DGGR variant offers tape-and-reel packaging, while DGG uses tube packaging. All variants share the core 28:4 serialization functionality and electrical specifications.

Replacement Considerations

SN65LVDS93DGGR serves as a direct functional alternative with identical electrical parameters but differs in reel packaging instead of tube. SN65LVDS93AIDGGRQ1 provides automotive qualification under AEC-Q100 standards with similar interface capabilities.
