93777BFLF

Application Specific Clock/Timing Overview

The 93777BFLF is a zero-delay buffer IC designed for DDR memory applications, manufactured by Renesas Electronics Corporation. It operates at a maximum frequency of 266MHz and requires a 3.3V supply voltage. The component is housed in a 28-SSOP package with dimensions of 0.209 inches (5.30mm) width. It functions within a commercial temperature range of 0°C to 70°C and features an internal PLL for clock synchronization.

Application Specific Clock/Timing Feature Summary

• Zero-delay buffering architecture ensures minimal skew between input and output clocks
• Integrated phase-locked loop (PLL) for precise clock signal generation
• Optimized specifically for high-speed DDR memory interface timing requirements

Application Specific Clock/Timing Applications

• DDR memory system clock distribution
• High-speed data acquisition systems
• Telecommunications equipment clocking
• Industrial control system timing

Application Specific Clock/Timing Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on authorized distributors or surplus suppliers. Confirm RoHS compliance status and check for any product change notices affecting pinout or electrical characteristics before integration into new designs.

Application Specific Clock/Timing Selection Notes

Select this part when designing DDR memory interfaces requiring zero-skew clock distribution. Ensure the design supports 3.3V logic levels and fits within the 0°C to 70°C operating temperature range. Verify that the 28-SSOP package footprint matches the PCB layout constraints and thermal requirements of the target application.

Application Specific Clock/Timing Part Context

The 93777BFLF belongs to the 93777B series of clock buffers from Renesas. It is part of the broader portfolio of timing solutions used in embedded systems. As an obsolete component, it represents legacy technology suitable for maintenance or replication of existing hardware rather than new development projects.

Application Specific Clock/Timing Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers should consult Renesas technical support for current alternatives compatible with DDR memory interfaces.
