49FCT3805DPYGI8

Overview

The 49FCT3805DPYGI8 is a dual 1-to-5 clock driver manufactured by Renesas Electronics. It operates on a single 3V to 3.6V supply and features LVCMOS input and output types. The device includes two independent driver banks, each with its own output enable control. It incorporates a heartbeat monitor for diagnostics and PLL driving, providing a MON output identical to other outputs. Designed for high-speed clock distribution, it ensures low skew and high signal quality. The component is housed in a 20-SSOP package and supports surface mount installation.

Feature Summary

• Dual 1:5 fanout clock drivers with independent output enable controls
• Integrated heartbeat monitor for diagnostics and PLL driving
• LVCMOS compatible inputs and outputs for low capacitance
• Operates within a 3V to 3.6V voltage range

Applications

• High-speed clock distribution systems requiring low skew
• Single point-to-point transmission line driving
• Address distribution to multiple receivers
• PLL driving applications

Procurement Notes

Verify the specific suffix 'D' against official Renesas documentation to confirm industrial temperature rating or specific manufacturing lot details, as standard variants may differ. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the SSOP-20 footprint matches the target PCB design constraints.

Selection Notes

Select this component when dual independent clock buffers are required with diagnostic capabilities. The 1:5 fanout ratio suits distributing a single clock source to five loads. Verify that the 3V-3.6V operating voltage aligns with the system power rails. The LVCMOS interface compatibility should be confirmed against the connected logic family specifications.

Part Context

This part belongs to the 49FCT series of Fast CMOS clock drivers. It is functionally related to the 49FCT3805A and 49FCT3805Q variants, differing primarily in package type (SSOP vs QSOP/SOIC) and potentially temperature grade indicated by the 'D' suffix. The series is designed for high-performance clock distribution in digital systems.

Replacement Considerations

Publicly documented substitutes include Diodes Incorporated PI49FCT32805QE. Verify pinout compatibility and electrical parameters such as propagation delay and drive strength before substitution. Other 49FCT3805 variants with different packages may serve as physical replacements if electrical specs match.
