91305AGLFT

Overview

The ICS91305AGLFT is a PLL-based clock driver from the 91305 series, manufactured by Integrated Device Technology (IDT), which is now part of Renesas Electronics. It features four true outputs and zero inverted outputs, housed in an 8-pin TSSOP package with a 0.65 mm pitch. The device operates as a zero-delay buffer, utilizing phase lock loop technology to align the REF input with the CLKOUT signal in both phase and frequency. It supports high-speed clock distribution in communication systems operating at frequencies from 10 MHz to 133 MHz. The component functions within a temperature range of -40 °C to 85 °C.

Feature Summary

• Zero-delay buffer architecture with skew less than +/- 350 pS between input and output
• Four true outputs for distributing high-speed clocks
• PLL-based synchronization aligning REF input with CLKOUT signal
• Operates at speeds from 10 MHz to 133 MHz

Applications

• Communication systems requiring high-speed clock distribution
• Systems needing synchronization between input and output signals
• Low skew clock buffering applications

Procurement Notes

Verify the manufacturer designation, as the part was originally produced by IDT before its acquisition by Renesas. Confirm the package type is TSSOP-8 and check for lead-free compliance (RoHS). Ensure the operating temperature range meets system requirements of -40 °C to 85 °C. Cross-reference the suffix 'GLFT' for tape and reel packaging specifications.

Selection Notes

Select this component when a low-jitter, low-skew clock driver is required for frequencies up to 133 MHz. The zero-delay buffer feature is critical for applications demanding precise phase alignment between reference and output clocks. Consider the 8-pin TSSOP package constraints for PCB layout. Verify that the single-function, four-output configuration matches the system's clock distribution needs.

Part Context

The ICS91305 belongs to the 91305 series of PLL-based clock drivers. IDT was acquired by Renesas Electronics Corporation, making this part part of Renesas's broader portfolio of timing solutions. The device is designed for performance-critical applications where clock integrity and synchronization are paramount.

Replacement Considerations

Check for direct pin-to-pin replacements within the Renesas/IDT portfolio that offer similar jitter and skew specifications. Verify compatibility with existing PLL configurations and output drive strengths. Ensure any substitute maintains the 10-133 MHz operational range and TSSOP-8 footprint.
