PI6C2405A-1HWIEX

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6C2405A-1HWIEX is a PLL-based zero-delay clock buffer manufactured by Diodes Incorporated. It distributes five 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 under 15pF load conditions. It features low cycle-to-cycle jitter of 200 ps and an input-to-output delay of less than 300 ps. The -1H suffix indicates a high-drive version compared to the standard variant. It is housed in an 8-pin SOIC (W) package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include the PI6C2405A-1WEX or PI6C2405A-1LEX for standard drive versions. For identical high-drive performance, verify pin-compatible alternatives within the same manufacturer's portfolio that maintain the 1:5 split ratio.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is zero delay achieved in this device?

Zero delay is achieved through an internal feedback connection on the OUT0 pin, which synchronizes all outputs to the CLKIN input.

What is the difference between the -1 and -1H variants?

The -1H variant is a high-drive version designed to handle larger capacitive loads compared to the standard -1 variant.

Does the device support spread spectrum clocking?

Yes, the PI6C2405A-1/PI6C2405A-1H is capable of tracking spread spectrum clocking signals to assist in EMI reduction.
