220 MHz zero-delay buffer with PLL bypass — what that means for your clock tree
The CY23EP09ZXC-1H is a Cypress zero-delay buffer that takes a single LVCMOS or LVTTL input and distributes it to nine LVCMOS outputs with near-zero propagation skew. The internal PLL locks to the input frequency and regenerates the outputs with deterministic phase alignment, which is the defining feature of a zero-delay buffer — the output edges align to the input edge within a few hundred picoseconds, not the propagation delay of a simple fanout gate. The PLL can also be bypassed, letting the device act as a straight fanout buffer when you need the lowest possible additive jitter or want to run at frequencies outside the PLL's lock range. Maximum output frequency is 220 MHz, with a second rating of 200 MHz. Supply voltage is dual-rated at 2.5 V and 3.3 V, so it fits into both legacy 3.3 V clock trees and lower-voltage 2.5 V designs without a separate level translator. The single-circuit, single-ended I/O (no differential inputs or outputs) keeps the pin count and board area down — 16-TSSOP is a compact footprint for a nine-output buffer.
Active lifecycle — no end-of-life risk for this BOM line
For a procurement decision, this means the part is safe to qualify into a new design today — no forced redesign cycle from obsolescence in the near term.
Temperature grade and package — commercial indoor use, surface-mount assembly
Operating temperature range is 0°C to 70°C, the commercial grade. This limits the part to indoor, temperature-controlled environments.
