Product details

Fanout and frequency — sizing the clock tree

With a 2:21 input-to-output ratio and a maximum output frequency of 200 MHz, this buffer can drive twenty-one loads from one or two reference clocks. That's enough fanout for a mid-size FPGA bank or a handful of SERDES transceivers. The non-differential I/O (No/No) means it's intended for single-ended LVCMOS distribution, not differential pairs like LVPECL or CML. If your design needs differential clocking, this isn't the part.

Temperature grade and environment

Rated for -40°C to +85°C ambient. The exposed pad requires a thermal via pattern under the pad for adequate heat transfer; the package itself is 7x7 mm.

Lifecycle and sourcing posture

RoHS non-compliant. Verify your assembly house's exemption policy if you need lead-free solder.

Frequently asked questions

What is the maximum frequency and output type for CY23020LFI-1?

Maximum output frequency is 200 MHz. All outputs are LVCMOS, single-ended. The part does not support differential outputs.

Is CY23020LFI-1 lead-free?

No, it is listed as RoHS non-compliant. Verify your assembly process if lead-free solder is required.
