PLL-based spread spectrum clocking at 65 MHz
The W166G from Infineon Technologies is a single-output spread spectrum clock generator with an integrated PLL. Its maximum output frequency of 65 MHz makes it suited for reducing electromagnetic interference (EMI) in digital clock trees running at common bus or interface frequencies. The supply range is 3.135 V to 3.465 V, a narrow 3.3 V nominal band that requires a clean rail — a local 100 nF ceramic cap at the supply pin is standard practice for this class of PLL-based device.
Package, temperature grade, and compliance check
The part is listed as RoHS non-compliant. If your BOM requires RoHS-10 or REACH compliance, this device will not pass a restricted-substance audit — factor a waiver or an alternative into the sourcing decision.
Sourcing and availability
The W166G is sourced through independent distribution channels.
