8402010AKILF

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS8402010AKILF is a low phase noise clock generator from the HiPerClockS family, manufactured by Renesas Electronics Corporation (formerly IDT). It converts a 25MHz crystal input into three output banks: Bank A and B provide single-ended LVCMOS signals at 16.66MHz, while Bank C delivers differential LVDS outputs at 62.5MHz. Additionally, it features a 25MHz reference clock output. The device operates on a full 3.3V supply with an ambient temperature range of -40°C to +85°C. It utilizes a 32-lead VFQFN package (5mm x 5mm) and achieves typical RMS phase jitter of less than 1ps, specifically 0.375ps at 62.5MHz.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three independent output banks: Banks A/B offer three single-ended LVCMOS outputs at 16.66MHz each; Bank C provides three differential LVDS outputs at 62.5MHz.
• Low phase jitter performance with a typical RMS value of 0.375ps at 62.5MHz (integration range 1.875MHz - 20MHz).
• Integrated PLL synthesizer generating frequencies from a 25MHz parallel resonant crystal input using internal dividers.
• Individual output enable control for all banks via dedicated OE pins, allowing flexible power management.

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed data communication systems requiring precise clock distribution.
• Networking equipment utilizing LVDS interfaces for high-frequency signal integrity.
• Embedded solutions needing multiple clock domains derived from a single crystal source.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the ordering suffix 'KI' corresponds to the lead-free RoHS6 compliant variant in the 32-lead VFQFN package. Confirm the manufacturer origin as Renesas Electronics Corporation, noting the historical IDT branding in documentation. Ensure the component matches the specific electrical characteristics for the AKI revision, particularly regarding the 3.3V supply requirements and thermal resistance parameters defined in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single crystal source must drive mixed LVCMOS and LVDS loads simultaneously. The device supports a maximum output frequency of 62.5MHz. Designers must account for separate power supplies (VDD, VDDA, VDDO_A/B/C) to isolate switching noise. Thermal management is critical due to the exposed pad; ensure adequate thermal vias are connected to ground to maintain junction temperature below 125°C under worst-case load conditions.
