Product details

200 MHz ceiling and 2:10 fanout — what they mean for your timing budget

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.

Lifecycle and sourcing

It is RoHS non-compliant per the original release, so verify your assembly house's exemption policy if you need lead-free.

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.
