87946AYI-147LF/W

Overview

The Renesas 87946AYI-147LF/W is a low skew, ÷1, ÷2 LVCMOS/LVTTL fanout buffer. It features ten single-ended outputs with 7Ω typical output impedance and two selectable single-ended clock inputs (CLK0/CLK1). The device supports frequencies up to 250 MHz. Supply voltage ranges are 2.375V–2.625V and 3.135V–3.465V. Operating temperature spans -40°C to +105°C. Package: 32-LQFP.

Feature Summary

Provides ten single-ended LVCMOS or LVTTL outputs for clock distribution
Features two selectable single-ended clock inputs (CLK0 and CLK1)
Supports frequency operation up to 250 MHz with low skew performance

Applications

Clock fanout buffer applications
LVCMOS/LVTTL signal distribution
Low skew clock generation systems

Procurement Notes

Verify the specific suffix 'W' against the manufacturer's datasheet to confirm RoHS compliance status and lead-free specifications. Ensure the package type matches the required 32-LQFP footprint. Confirm supply voltage requirements align with the specified dual range of 2.375V–2.625V and 3.135V–3.465V before procurement.

Selection Notes

Select this component when a low skew fanout buffer with ten outputs is required. It supports both LVCMOS and LVTTL interfaces via selectable inputs. Verify that the operating temperature range of -40°C to +105°C meets system environmental constraints. Ensure the input frequency does not exceed 250 MHz for proper functionality.

Part Context

This part belongs to the Renesas 87946 series of clock generators and support products. It functions as a fanout buffer designed to distribute clock signals with minimal skew. The series typically includes variants with different output counts and interface types, serving various digital system synchronization needs.

Replacement Considerations

Consult official substitution lists for direct equivalents. Generic cross-references may lack verified electrical compatibility. Verify pinout and voltage levels before substituting.
