PI6C2405A-1WEX

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6C2405A-1WEX is a PLL-based zero-delay clock buffer manufactured by Diodes Incorporated. It distributes five outputs from a single CLKIN input, supporting frequencies up to 133 MHz at a 3.3V supply voltage. The device features an internal feedback loop on OUT0 to synchronize outputs and minimize input-to-output delay to less than 300 ps. It operates within a commercial temperature range of 0°C to 70°C and an industrial range of -40°C to 85°C. The component is housed in an 8-pin SOIC (W) package with a 150-mil width.

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. When all outputs are loaded equally, the relationship between the OUT0 signal loading and other outputs minimizes the input-to-output delay.

What is the maximum rated frequency for this buffer?

The maximum rated frequency is 133 MHz when operating with a 15 pF load capacitance.

Does the device support spread spectrum clocking?

Yes, the PI6C2405A-1WEX is designed to track spread spectrum clocking signals to assist in EMI reduction.
