49FCT805PYG

Overview

The Renesas Electronics Corporation 49FCT805PYG is a dual clock driver and distribution buffer belonging to the 49FCT series. It features two independent circuits, each providing a 1-to-5 fan-out ratio with CMOS outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports maximum output frequencies up to 166 MHz. It is housed in a 20-pin SSOP package (0.209 inch width) designed for surface mount installation. The component functions as a low skew clock buffer suitable for high-speed digital systems.

Feature Summary

• Dual circuit architecture with 1:5 input-to-output ratio per channel
• CMOS output type compatible with LVTTL inputs
• Maximum operating frequency of 166 MHz
• Supply voltage range of 4.5V to 5.5V

Applications

• High-speed clock distribution networks
• System timing synchronization
• Digital signal processing interfaces

Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited stock. Confirm RoHS compliance details through official datasheets before procurement. Ensure the SSOP-20 package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component when a dual-channel 1:5 fan-out buffer is required for 5V logic systems. Verify that the 166 MHz frequency capability meets the system clock speed requirements. Ensure the design accommodates the 20-SSOP package constraints and thermal dissipation needs for surface mount assembly.

Part Context

This part is part of the broader 49FCT family of fast CMOS clock drivers. Variants such as 49FCT805CTSOG and 49FCT805SO8 share similar functional characteristics but differ in package types like SOIC or QSOP. The PYG suffix specifically denotes the SSOP-20 package configuration.

Replacement Considerations

Direct substitutes include other 49FCT805 variants with different packages, such as 49FCT805SO8 (SOIC-20) or 49FCT805CTQG (QSOP-20). Cross-reference pinouts and electrical specifications to ensure compatibility.
