SN65LVDS93BDGG

Overview

The SN65LVDS93BDGG is a serializer IC manufactured by Texas Instruments, designed for high-speed data transmission in flat panel display applications. It accepts 28 parallel LVTTL inputs and serializes them into four LVDS differential output pairs. The device supports data rates up to 2.38 Gbps with an input clock frequency range of 10 MHz to 85 MHz. It operates on a single 3.3 V power supply, with a voltage range of 3.0 V to 3.6 V. The component is housed in a 56-pin TSSOP package measuring 14 mm x 6.1 mm x 1.15 mm. It functions within a commercial temperature range of -40°C to +85°C.

Feature Summary

• Performs 28-to-4 channel data compression for efficient point-to-point subsystem communication
• Features low electromagnetic interference (EMI) characteristics to meet strict compatibility standards
• Supports flexible clock triggering via selectable rising or falling edge inputs
• Provides robust electrostatic discharge (ESD) protection on bus pins

Applications

• Flat panel display systems requiring high-bandwidth video data transmission
• Point-to-point subsystem communication in complex electronic architectures
• High-density digital interfaces where EMI reduction is critical

Procurement Notes

Verify the specific suffix 'BDGG' corresponds to the tube packaging format rather than reel variants like 'DGGR'. Confirm that the AEC-Q100 qualification applies only to the 'AIDGGRQ1' variant, as the standard BDGG part may lack automotive certification. Ensure the design-in guidelines for channel-link PCB interconnects are consulted to maintain signal integrity at the specified 2.38 Gbps rate.

Selection Notes

Select this component when a 28-input serializer is required for LVDS transmission. Compare against the SN65LVDS93A series if higher data rates up to 135 MHz are needed. Verify that the 56-pin TSSOP footprint fits the board layout constraints. Consider the SN65LVDS93AZQLR if a BGA package is preferred for space-constrained designs, noting its different pinout and form factor.

Part Context

This device belongs to the SN65LVDS93 family of FlatLink serializers. It complements deserializers such as the SN65LVDS94 to form complete serializing/deserializing links. The BDGG suffix specifically denotes the surface-mount TSSOP package type. It is distinct from the automotive-grade AIDGGRQ1 and the discontinued AZQLR BGA version.

Replacement Considerations

The SN65LVDS93BDGG can be replaced by the SN65LVDS93BDGGR, which shares identical electrical specifications but utilizes tape-and-reel packaging instead of tubes.
