IDT49FCT3805ASOI

Clock Buffers, Drivers Overview

The IDT49FCT3805ASOI is a dual 1:5 clock buffer and driver manufactured by Renesas Electronics Corporation. Built using advanced CMOS technology, the device operates at a supply voltage of 3.3V (±0.3V). It contains two independent driver banks, each providing a 1:5 fanout with individual output enable controls. The component features low capacitance inputs with hysteresis and guarantees a maximum skew of less than 500ps. It supports TTL-compatible inputs and outputs, allowing driving from both 3.3V and 5V components.

Clock Buffers, Drivers Feature Summary

• Dual independent 1:5 fanout clock driver banks
• Guaranteed low skew < 500ps (max.)
• Very low duty cycle distortion < 1.0ns (max.)
• Includes 'heartbeat' monitor output for diagnostics

Clock Buffers, Drivers Applications

• High-speed clock distribution systems
• Address distribution in point-to-point transmission lines
• PLL driving applications requiring signal integrity

Clock Buffers, Drivers Procurement Notes

Verify the package designation carefully. The suffix 'SOI' typically indicates a SOIC-20 package. Confirm the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required temperature ranges and RoHS compliance status before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and high signal quality are critical for clock distribution. Ensure the design accommodates the 3.3V supply voltage range (3V to 3.6V). Verify that the input logic levels match the TTL-compatible requirements and that the 1:5 fanout per bank meets the system's load requirements.

Clock Buffers, Drivers Part Context

This part belongs to the 49FCT series of Fast CMOS buffers and drivers. It is functionally similar to other variants like the IDT49FCT3805APY (SSOP) or IDT49FCT3805AQGI (QSOP), differing primarily in the physical package type while maintaining identical electrical characteristics and pinouts.
