552-02SCMGI

Overview

The Renesas Electronics 552-02SCMGI is a low skew clock buffer and multiplexer from the 552S series. It features a single input to eight-output configuration with dual inputs for pin-selectable clock source switching. The device offers low RMS additive phase jitter of 50 fs and low output skew of 50 ps, supporting input/output clock frequencies up to 200 MHz. It operates on supply voltages ranging from 1.8 V to 3.3 V and is packaged in a 16-pin TSSOP or VFQFPN format. Designed with low power CMOS technology, it includes an output enable pin to tri-state outputs and supports extended temperature ranges.

Feature Summary

• Low RMS additive phase jitter of 50 fs
• Dual input with pin select for clock source switching
• Supports clock frequencies up to 200 MHz
• Output enable pin for tri-stating outputs

Applications

• Clock distribution networks requiring low jitter
• Systems needing selectable clock sources via hardware pin
• High-speed digital circuits operating at 200 MHz

Part Context

This component belongs to the 552S family of clock buffers and drivers. It is functionally similar to other variants like the 552-02S but distinguished by its specific packaging suffix (CMGI) indicating a 16-pin TSSOP or VFQFPN package. It serves as a direct replacement for standard 1:8 clock buffers where low skew and multiplexing capabilities are required.

Replacement Considerations

Verify package compatibility when substituting with other 552S variants. Ensure the substitute part supports the required 1.8V to 3.3V supply range and 200 MHz frequency. Check if the alternative provides the same dual-input pin-select feature.
