PI6C2409-1HLIE

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6C2409-1HLIE is a PLL-based zero-delay clock buffer manufactured by Diodes Incorporated. It distributes nine outputs from a single CLKIN input, with OUT0 providing internal feedback for synchronization. The device operates at 3.3V VDD and supports frequencies up to 133 MHz. It features two banks of four outputs controlled by SEL1 and SEL2 inputs, allowing selection between PLL or direct CLKIN sources. The component is characterized for industrial operation within a temperature range of -40°C to +85°C and is available in a 16-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay buffering capability using internal feedback on the OUT0 pin to synchronize outputs with the clock input.
• Configurable output sourcing via SEL1 and SEL2 pins, enabling selection between PLL-generated clocks or direct CLKIN reference.
• Power-saving bypass mode that turns off the PLL when specific select inputs are set, referencing all outputs directly to CLKIN.
• Spread spectrum compatibility designed to reduce electromagnetic interference (EMI) in high-speed digital systems.

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed networking equipment requiring precise clock distribution.
• Industrial control systems operating in harsh thermal environments.
• Servers and storage arrays needing low-jitter clock signals.
• Telecommunications infrastructure utilizing spread spectrum techniques.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the 'L' suffix indicates the 16-pin TSSOP package. Ensure the 'E' suffix denotes Pb-free and Green material compliance. Cross-reference the datasheet revision to confirm electrical characteristics match the design requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for applications requiring a 1:9 fanout with zero-delay synchronization at 3.3V. Choose the Industrial grade version for environments exceeding commercial temperature limits. Verify load capacitance requirements against the specified 15pF limit for frequencies above 100 MHz. Consider the power-saving bypass feature if system testing requires disabling the PLL.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the PI6C2409-1H series of zero-delay buffers. It shares functional similarities with other members like the PI6C2408 but offers a 1:9 output configuration compared to the 1:8 variant. The series is designed for high-performance clock distribution in space-constrained designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

PI6C2409-1HLE serves as the commercial temperature equivalent. PI6C2409-1HLIEX provides the same industrial specifications but in tape and reel packaging. Direct substitutes must maintain the 1:9 output count and 3.3V operation voltage.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is zero delay achieved in the PI6C2409-1HLIE?

Zero delay is achieved through an internal feedback connection on the OUT0 pin. This synchronizes the outputs to the input, provided that the loading on OUT0 matches the loading on the other outputs.

What is the function of the SEL1 and SEL2 pins?

These selection inputs control the source of the outputs. Setting SEL1=0 and SEL2=1 bypasses the PLL, referencing all outputs directly to CLKIN. Other combinations enable the PLL for synchronized output generation.

What is the maximum operating frequency for this device?

The maximum rated frequency is 133 MHz when the load capacitance is 10pF. At a higher load of 30pF, the maximum frequency is limited to 100 MHz.
