Clock generator with fanout — what it does on the board
The Infineon (Cypress) CY22050KFI is a programmable clock generator with fanout distribution, built around a PLL that includes a bypass mode. It takes a single input — LVCMOS, LVTTL, or a crystal — and delivers six CMOS clock outputs. The PLL can multiply the reference up to 150 MHz on one output path and 166.6 MHz on another, so you can drive different clock domains from one reference. The bypass path lets you feed a clean reference through for test or low-jitter modes without touching the PLL.
Supply voltage and temperature — where it fits
Runs on either 2.5 V or 3.3 V, which covers the two most common digital supply rails in mixed-signal and processor boards. No level shifters needed if the rest of the clock tree lives at one of those voltages. The -40°C to 85°C range puts it in the industrial bracket — outdoor telecom cabinets, factory-floor PLCs, motor drives, engine-bay electronics. Not a mil-grade part, but it handles the thermal cycling a production line or a rooftop radio sees.
Package and footprint — 16-TSSOP
Housed in a 16-TSSOP with a 4.40 mm body width. Surface-mount only, so it needs a reflow profile — no socket option for field swapping. The 0.65 mm pitch is fine for hand-assembly with a fine tip if you are doing a prototype run, but production goes through the oven. No exposed pad, so thermal management is through the leads and the board copper.
