552-02SCMGI8

Overview

The 552-02SCMGI8 is a low skew clock buffer and multiplexer manufactured by Renesas Electronics. It features a single input to eight-output configuration with dual inputs for pin-selectable clock source switching. The device provides an additive phase jitter of 50 fs RMS and output skew of 50 ps, supporting input/output frequencies up to 200 MHz. It operates on supply voltages ranging from 1.8 V to 3.3 V and utilizes low power CMOS technology. The component is designed for applications requiring precise clock distribution and selection within extended temperature ranges.

Feature Summary

• Low RMS additive phase jitter of 50 fs
• Dual input with pin select for clock source switching
• Operating voltage range of 1.8 V to 3.3 V
• Input/Output clock frequency up to 200 MHz

Applications

• Clock distribution networks
• System synchronization
• High-speed data acquisition systems

Part Context

This component belongs to the 552S series of clock buffers and drivers. It integrates multiplexing capabilities directly into the buffer architecture, allowing for simplified board-level clock selection without external logic. The device is part of Renesas' portfolio focused on low jitter timing solutions.

Replacement Considerations

The 552-02S is the base part number for this family. Verify if the specific suffix 'CMGI8' denotes the required package type (TSSOP/VFQFPN) and temperature grade (-40°C to +105°C). Ensure any substitute supports the 1:8 buffering ratio and 200 MHz maximum frequency.
