Overview
The SN65LVDS93DGGR is a serializer manufactured by Texas Instruments, designed to compress 28 parallel LVTTL inputs into four LVDS differential outputs. It operates at a maximum data rate of 1.904Gbps with a supply voltage range of 3V to 3.6V. The device utilizes a 56-TSSOP package and supports an operating temperature range from -40°C to 85°C. Key electrical parameters include 28 input channels, 4 output channels, and LVTTL input compatibility.
Feature Summary
- Performs high-speed data compression by converting 28-bit parallel LVTTL data streams into four serial LVDS channels.
- Features low electromagnetic interference (EMI) characteristics suitable for dense electronic environments.
- Provides robust electrostatic discharge (ESD) protection on bus pins rated at 6kV human body model.
Applications
- Point-to-point subsystem communication in complex electronic systems
- High-speed data transmission interfaces requiring channel reduction
- Applications demanding low EMI emissions and high reliability
Procurement Notes
Verify the specific suffix DGGR against official datasheets to confirm the tape and reel packaging configuration. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and avoid counterfeit risks during sourcing.
Selection Notes
Select this component when a 28:4 compression ratio is required for LVTTL to LVDS conversion. Verify that the system clock frequency aligns with the 1.904Gbps maximum throughput capability. Confirm that the 56-TSSOP package dimensions fit the available PCB real estate and thermal management constraints.
Part Context
This device belongs to the SN65LVDS93 family of serializers. It is functionally related to the SN65LVDS93AD variant, which offers higher speed capabilities up to 3.78Gbps. Both share similar pinouts and interface standards but differ in performance specifications.
Replacement Considerations
The SN65LVDS93ADGGR is a parameter-equivalent alternative offering higher speed performance. Verify if the increased bandwidth of the AD variant is compatible with the existing system clocking architecture before substitution.
