5T30553DCGI

Overview

The 5T30553DCGI is a low-power, high-performance clock buffer manufactured by Renesas Electronics. It features four outputs with low skew characteristics and supports input frequencies up to 200 MHz. The device operates within a supply voltage range of 1.71 V to 3.465 V and is designed for industrial temperature applications ranging from -40°C to +105°C. Key electrical parameters include a maximum propagation delay of 4 ns and a typical output skew of 50 fs. It is housed in a surface-mount package suitable for automated assembly.

Feature Summary

• Four low-skew outputs with 50 fs typical skew performance
• Supports input frequencies up to 200 MHz
• Wide operating voltage range: 1.71 V to 3.465 V
• Industrial temperature range: -40°C to +105°C

Applications

• High-speed data communication systems
• Networking equipment requiring precise clock distribution
• Industrial control systems with strict timing requirements
• Test and measurement instruments

Procurement Notes

Verify the specific ordering suffix 'DCGI' against the official Renesas datasheet to confirm package type, pinout, and environmental compliance. Ensure that the selected variant matches the required operating temperature range and voltage specifications for the target application design.

Selection Notes

Select this component when low skew and high frequency buffering are critical. Compare the 4 ns max propagation delay against system timing budgets. Verify compatibility with the 1.71 V to 3.465 V supply rails and ensure the SMD package fits the PCB layout constraints.

Part Context

This part belongs to the 5T3055 series of clock buffers from Renesas. It is distinct from other series like the 551S or 553S which may have different skew specifications or power profiles. The 5T30553DCGI is specifically engineered for low-jitter applications requiring multiple buffered outputs from a single source.

Replacement Considerations

Check for direct cross-references in Renesas's product transition notices. Alternative parts must match the 4-output configuration, 200 MHz frequency limit, and similar skew specifications. Verify pin-to-pin compatibility if substituting with other low-skew buffer families.
