What this clock generator does on your board
The Cypress CY28326OXC is a PLL-based clock generator that takes a single clock input and distributes it to 24 clock outputs. That 1:24 fanout ratio means one reference oscillator can feed a whole board of processors, FPGAs, or memory controllers without daisy-chaining or extra buffers. The PLL cleans up jitter and can synthesize a different output frequency from the input — useful when the system clock is one speed but the CPU bus runs at another. Supply range is 3.135 V to 3.465 V. The part is single-ended throughout — no differential I/O — so it mates directly to LVCMOS or LVTTL clock trees. No internal divider or multiplier; the PLL's multiplication ratio is set by the processor-specific configuration, not a user-programmable divider.
Sourcing and lifecycle
The CY28326OXC is listed as Active and ROHS3 compliant. No NRND or EOL flags, no last-time-buy window to track.
