PI6C2405A-1HLEX

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6C2405A-1HLEX 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 maximum rated frequencies up to 133 MHz. Key electrical parameters include an input-to-output delay of less than 300ps, cycle-to-cycle jitter of 200 ps (measured at 66.67 MHz with 30pF load), and output-to-output skew of 200 ps under equal loading conditions. It features 5V tolerant inputs and spread spectrum clocking readiness.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. The 'L' suffix indicates an 8-pin TSSOP package, while 'W' denotes an SOIC package. Ensure the '-1H' designation matches the required drive strength specifications for the target application design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the -1H variant when higher drive current capability is necessary compared to the standard -1 version. Confirm that the load capacitance requirements align with the specified frequency limits, as the maximum operating frequency decreases with increased capacitive loading. Verify that the input voltage thresholds are compatible with the 5V tolerance specification.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is zero delay achieved in this device?

Zero delay is achieved through an internal feedback loop connected to the OUT0 pin. This feedback synchronizes the outputs to the input clock, minimizing the propagation delay between the rising edge of CLKIN and the rising edge of OUT0.

What determines the relationship between loading and input-output delay?

The relationship between the loading of the OUT0 signal and the other outputs determines the input-output delay. Zero delay is specifically achieved when all outputs, including the feedback pin, are loaded equally.

Does the device support spread spectrum clocking?

Yes, the PI6C2405A-1/PI6C2405A-1H is capable of tracking spread spectrum clocking signals, which helps in reducing electromagnetic interference (EMI) in the system.
