The 200 MHz maximum frequency covers most SPI, Ethernet, and DDR memory reference clocks, but not high-end SERDES or RF synthesizers. The 2:10 input-to-output ratio means you can feed two independent clock sources (say, a primary oscillator and a backup) and route either to up to ten loads, or split the outputs between the two inputs. Because the part is single-ended only (no differential I/O), it is best suited for single-ended clock trees driving CMOS loads — not for LVDS or LVPECL fanout.

Frequently asked questions
Is CY29946AIT compatible with 3.3V LVCMOS inputs?
Yes, the CY29946AIT accepts LVCMOS and LVTTL inputs, and its output supply range of 2.97 V to 3.63 V covers 3.3 V logic levels. The core supply can be set to 2.5 V or tied to the same 3.3 V rail.
