91305AMILFT

Overview

The Renesas 91305AMILFT is a high-performance communication buffer designed for distributing high-speed clocks in communication systems. It utilizes phase lock loop (PLL) technology to align the REF input with the CLKOUT signal in both phase and frequency, achieving zero input-output delay. The device operates within a frequency range of 10 MHz to 133 MHz at 3.3V supply voltage. It features less than 200 ps jitter between outputs and skew controlled outputs with skew less than 250 ps. The component supports industrial temperature ranges from -40°C to +85°C and is available in an 8-pin TSSOP package.

Feature Summary

• Zero input-output delay using PLL technology for precise clock alignment
• Low skew and low jitter performance suitable for high-speed data transmission
• High loop filter bandwidth optimized for spread spectrum applications

Applications

• Communication systems requiring high-speed clock distribution
• Spread spectrum clock generation applications
• Industrial equipment operating in wide temperature environments

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status and lead-free characteristics before procurement. Ensure the selected variant matches the required package type and temperature grade for your specific design implementation.

Selection Notes

Select this component when zero delay clock buffering is critical for system synchronization. Consider the 10-133 MHz operational range and 3.3V logic compatibility. Evaluate the 8-pin footprint constraints against board space requirements. Verify that the jitter specifications meet the timing integrity needs of the target communication interface.

Part Context

This part belongs to the family of high-performance communication buffers manufactured by Renesas Electronics Corporation, formerly Integrated Device Technology. These components are engineered to provide reliable clock distribution solutions for digital systems requiring precise timing alignment and minimal signal distortion across multiple output channels.

Replacement Considerations

Cross-reference with other zero-delay buffer models from Renesas or compatible manufacturers such as Exar XRK series. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any functional differences in loop filter bandwidth or jitter performance metrics.
