Product details

What this zero delay buffer does on the board

The Renesas 2305-1DCGI is a single-circuit zero delay buffer with an internal PLL that can be bypassed, accepting an LVTTL input and distributing it as CMOS, LVCMOS, or TTL outputs across a 1:5 fanout ratio. The PLL with bypass feature means you can either clean up a jittery incoming clock or, when bypassed, simply fan out a clean clock without added phase noise — useful for debugging or low-jitter paths.

Where it fits — temperature and package

Surface-mount only — no through-hole version.

Frequently asked questions

Can the 2305-1DCGI be used as a 1:5 clock buffer at 133 MHz with 3.3V supply?

Yes. It is a 1:5 fanout zero delay buffer rated for up to 133 MHz with a 3V to 3.6V supply. The PLL can be bypassed for a clean fanout or engaged for jitter cleaning.
