|---|---|---|---|---|
| FFF Compatibility | Matches the 8-TSSOP footprint and has an identical pinout configuration (pin 1 input, pin 2 enable, pin 4 ground, pin 6 power, and pins 3, 5, 7, 8 as clock outputs).Housed in an identical 8-TSSOP package with a 4.40mm body width.Operates as a 1:4 clock fanout buffer supporting 3.3V supply voltage while exceeding the original's frequency capability. | Shares the exact same pin assignments for clock input, output enable, supply, ground, and all four clock outputs.Supplied in the identical 8-TSSOP footprint.Functions as a 1:4 LVCMOS clock buffer operating at 3.3V and meeting all primary electrical and timing specifications. | ||
 AI Summary | CY2304NZZXC-1 by Infineon Technologies: PCI Express (PCIe) Zero Delay Buffer IC 140MHz 1 Output 8-TSSOP. | The LMK1C1104PWR is a highly efficient, modern 1:4 clock buffer that serves as an excellent drop-in replacement. It offers superior jitter performance, wider temperature tolerance, and supports lower logic levels if the board design is updated.
| The CDCV304PW is a robust, PCI-X compliant 1:4 clock buffer from Texas Instruments. It provides an exact electrical and physical match, ensuring seamless operation in legacy and high-speed clock distribution networks.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Infineon Technologies CY2304NZZXC-1 is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Infineon Technologies CY2304NZZXC-1 are the LMK1C1104PWR (Texas Instruments) and the CDCV304PW (Texas Instruments), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the CY2304NZZXC-1 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
