MC88920EGR2

Overview

The MC88920EGR2 is a single-circuit clock buffer integrated circuit manufactured by Renesas Electronics Corporation. Designed for CISC and RISC microprocessor applications, it accepts CMOS or TTL inputs and provides six CMOS outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum frequency of 50MHz. It functions without differential signaling capabilities and includes an internal PLL. The component is housed in a 20-SOIC surface-mount package with a width of 7.50mm and is rated for operation between 0°C and 70°C.

Feature Summary

• Single circuit configuration with one input and six outputs
• Compatible with CMOS and TTL input logic levels
• Internal phase-locked loop (PLL) functionality
• Surface mount 20-SOIC package

Applications

• CISC/RISC Microprocessor clock distribution
• System clock buffering
• Digital signal processing timing circuits

Procurement Notes

Verify the specific ordering suffix EGR2 against official Renesas documentation to confirm package type and temperature range. Ensure compatibility with existing 4.5V–5.5V power rails and 50MHz frequency requirements. Confirm that the 20-SOIC footprint matches the target PCB design. Check for any RoHS compliance markings if required by local regulations.

Selection Notes

Select this component when a single-input, six-output clock buffer is required for microprocessor systems. It is suitable for designs using CMOS or TTL logic families. The 50MHz maximum frequency limit must be considered for high-speed applications. The absence of differential I/O makes it appropriate for single-ended clock distribution networks only.

Part Context

This part belongs to the Application Specific Clock/Timing category. It serves as a buffer amplifier to drive multiple loads from a single clock source. The inclusion of a PLL allows for frequency synthesis or jitter reduction within the specified operating parameters.

Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Ensure replacement parts match the 20-SOIC package, 1:6 ratio, and 4.5V–5.5V supply voltage constraints.
