551SPGGI8

Overview

The Renesas 551SPGGI8 is a low-cost, high-speed single-input to four-output LVCMOS clock buffer from the 551S family. It features extremely low skew outputs of 50ps and an additive phase jitter RMS of 50fs. The device supports input/output clock frequencies up to 200 MHz with non-inverting outputs. It operates within a supply voltage range of 1.71 V to 3.465 V and functions across an extended temperature range of -40 °C to +105 °C. Packaged in an 8-pin TSSOP (0.65 mm pitch), it utilizes an advanced low-power CMOS process.

Feature Summary

• Low additive phase jitter RMS: 50fs
• Extremely low skew outputs: 50ps
• Input/Output clock frequency up to 200MHz
• Operating voltages: 1.8V to 3.3V

Applications

• Networking clocks
• High-speed data transmission systems
• Telecommunications equipment

Procurement Notes

Verify the specific suffix GI8 confirms the TSSOP package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for the assembly line. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select the 551SPGGI8 when a small form factor is required due to its TSSOP package compared to SOIC alternatives. Ensure the design accommodates the 1.8V to 3.3V operating voltage range. Verify that the 200 MHz maximum frequency meets the system timing requirements.

Part Context

The 551SPGGI8 belongs to the 551S series of low-cost, high-speed clock buffers. This series includes variants like 551SDCGI8 (SOIC) and 551SCMGI8 (DFN). The SPGGI8 variant specifically denotes the TSSOP package option within this family.

Replacement Considerations

The 551SDCGI8 serves as a parameter-equivalent alternative with identical electrical specifications but differs in package type (SOIC vs. TSSOP). Cross-reference pinouts and thermal performance if substituting packages.
