551SPGGI

Overview

The Renesas Electronics 551SPGGI is a low-cost, high-speed single-input to four-output LVCMOS clock buffer belonging to the 551S series. It provides non-inverting output clocks with an input/output frequency capability of up to 200 MHz. The device features extremely low skew outputs of 50 ps and best-in-class additive phase jitter of sub-50 fs RMS. It operates within a supply voltage range of 1.8 V to 3.3 V and supports an extended temperature range from -40 °C to +105 °C. Packaged in an 8-pin TSSOP, it utilizes an advanced low-power CMOS process and includes an output enable mode for tri-state outputs.

Part Context

The 551SPGGI is part of the 551S family of low skew clock buffers. This family offers cost-effective solutions for distributing clock signals in high-speed digital applications. Other variants in the series include packages such as SOIC (e.g., 551SDCGI) and COL (e.g., 551SCMGI), providing flexibility in form factor selection while maintaining similar electrical performance characteristics.

Replacement Considerations

For pin-compatible alternatives within the same package, consider the 551SPGG (tube packaging) or other members of the 551S family like the 551SDCGI if SOIC packaging is acceptable. Verify that the specific suffix requirements match the desired packaging type.
