PI6C2405A-1HLE

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6C2405A-1HLE is a PLL-based zero-delay clock buffer manufactured by Diodes Incorporated. It operates at a supply voltage of 3.3V with a range of 3.0V to 3.6V. The device supports output frequencies from 10 MHz to 133 MHz and features five outputs (OUT0–OUT4). OUT0 provides internal feedback for zero-delay synchronization, achieving an input-to-output delay of ±300 ps. Output-to-output skew is limited to 200 ps under equal loading conditions. Cycle-to-cycle jitter is specified at 200 ps maximum. The component is available in an 8-pin TSSOP package.

• Synchronization of multiple peripheral devices
• EMI reduction in high-frequency circuits via spread spectrum operation

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature rating. The 'L' suffix indicates an 8-pin TSSOP package, while 'E' denotes lead-free and green material compliance. Confirm whether the 'I' suffix is required for industrial temperature ranges (-40°C to +85°C) or if commercial grades are sufficient for the application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low skew and precise timing alignment are critical for distributing a single clock source to multiple loads. Ensure that the load capacitance requirements match the operating frequency, as higher frequencies up to 133 MHz require lower load capacitance (15 pF) compared to frequencies below 100 MHz (30 pF). Verify that the input clock signal meets the necessary voltage threshold requirements for proper PLL locking.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the PI6C2405A series of zero-delay clock buffers. The -1H designation identifies it as the high-drive version of the standard -1 model. The -LE suffix specifies the 8-pin TSSOP package with lead-free and green manufacturing attributes. This family is designed for applications requiring minimal propagation delay between the input reference and the distributed outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The PI6C2405A-1HWE serves as a package alternative offering the same electrical characteristics in an 8-pin SOIC format. When substituting, ensure the PCB footprint accommodates the different package dimensions. Verify that the thermal performance and mechanical mounting constraints of the target design support the replacement package type.
