IDT5V551DCGI

Clock Buffers, Drivers Overview

The IDT5V551DCGI is a low skew clock buffer manufactured by Renesas Electronics, operating within the industrial temperature range of -40°C to +85°C. It utilizes an advanced CMOS process to provide a 1:4 fanout from a single input to four true outputs. The device supports LVTTL input and output signaling with a maximum frequency of 160 MHz. It functions on a supply voltage range of 3V to 3.6V. The component is housed in an 8-SOIC package (0.154 inch width) and features non-inverting outputs suitable for efficient clock distribution networks.

Clock Buffers, Drivers Procurement Notes

Verify the manufacturer designation as Renesas Electronics or IDT, reflecting the corporate acquisition history. Confirm the specific suffix 'DCGI' corresponds to the SOIC-8 package and industrial temperature grade (-40°C to +85°C). Ensure RoHS compliance status matches current manufacturing standards, as legacy documentation may list lead-free availability separately. Cross-reference the part number against official Renesas databases to confirm active status and final revision details.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source requires distribution to four loads with minimal skew. Verify that the system logic levels are compatible with LVTTL standards. Ensure the operating environment remains within the specified -40°C to +85°C range. Confirm that the 3V to 3.6V supply voltage aligns with the target circuit design. Consider the 160 MHz maximum frequency limit relative to the application's timing requirements.

Clock Buffers, Drivers Part Context

This component belongs to the 5V551 series of low skew clock drivers. The series is designed using advanced CMOS technology to offer low power consumption and high performance. The 1:4 configuration is standard for buffering signals in digital systems where signal integrity and timing precision are critical across multiple downstream components.

Clock Buffers, Drivers Replacement Considerations

The IDT5V551DCI is a direct functional equivalent within the same package and specification set. Verify pin compatibility and electrical parameters before substitution. Other 1:4 clock buffers from different manufacturers require careful evaluation of voltage levels, skew specifications, and package dimensions.
