ICS552G-02IT

Clock Buffers, Drivers Overview

The ICS552G-02IT is a ClockBlocks™ series clock buffer and multiplexer manufactured by Renesas Electronics Corporation. It features a 2:8 input-to-output ratio, supporting maximum frequencies of 200 MHz. The device operates on a single supply voltage ranging from 2.375 V to 5.25 V and is housed in a 16-TSSOP package with a width of 4.40 mm. Designed for surface mount installation, it functions within an industrial temperature range of -40°C to +85°C. The component utilizes low power CMOS technology and provides one circuit configuration.

Clock Buffers, Drivers Feature Summary

• Integrated 2-input multiplexer simplifies clock source selection via pin select
• Low skew performance with output skew of 50 ps and additive phase jitter of 50 fs RMS
• Supports operating voltages from 1.8 V to 3.3 V (with broader 2.375 V–5.25 V specification)
• Includes output enable pin to tri-state outputs

Clock Buffers, Drivers Applications

• Clock distribution in high-speed digital systems
• Multiplexing between two clock sources
• Industrial control systems requiring extended temperature operation

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'IT' against the official datasheet to confirm the temperature grade and packaging variant. Ensure compatibility with the required supply voltage range of 2.375 V to 5.25 V. Confirm that the 16-TSSOP footprint matches the PCB layout constraints. Cross-reference the RoHS3 compliance status if environmental regulations apply to the target assembly.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew clock buffer with dual-input multiplexing capability is required. The 200 MHz maximum frequency suits moderate-speed clock distribution networks. Consider the 16-TSSOP package size for space-constrained designs. Verify that the input/output logic levels are compatible with the system's CMOS requirements.

Clock Buffers, Drivers Part Context

This part belongs to the Renesas ClockBlocks™ family, which specializes in clock management solutions. The 552G series is designed to provide precise timing signals with minimal jitter. It serves as a direct replacement or upgrade for legacy clock buffers in applications demanding improved signal integrity and flexible clock source selection.

Clock Buffers, Drivers Replacement Considerations

The 552G-02ILN is listed as a substitute part number by distributors. Verify electrical parameter equivalence and package compatibility before substitution.
