Its 1:24 output ratio means one input drives up to 24 clock loads, which matters when populating a multi-IC board where a single reference must feed several PLLs or ASICs without adding a separate clock fanout device. ## Supply rails and output frequencies The three maximum output frequencies (14.318 MHz, 24 MHz, 48 MHz) cover common reference rates for Ethernet PHYs, USB controllers, and SoC core clocks, but the actual output set is fixed by the internal divider chain; the buyer should confirm the specific output frequencies against the BOM requirement before committing the PCB. No differential outputs (PECL/LVDS) and no internal divider or multiplier means the device is a straightforward clock generator for single-ended CMOS clock trees. The 2-circuit count and 1:24 input-to-output ratio indicate two independent PLL banks sharing the same crystal reference, each driving up to 12 outputs — useful for splitting clock domains on a mixed-frequency board without adding a second oscillator. ## Package and board-fit for PCB layout Housed in a 48-TFSOP (0.240\", 6.10 mm width) body, also listed as the supplier device package 48-TSSOP — same footprint, same 0.50 mm pitch. The surface-mount package demands a controlled-impedance layout on the clock output traces; the narrow pitch also means the decoupling capacitors for the dual supply rails must sit within 2-3 mm of the respective VDD pins to keep the PLL jitter within spec.","metaTitle":"Infineon W48S87-72XT PLL Clock Generator, 48MHz, 48-TSSOP","metaDescription":"Active Infineon W48S87-72XT PLL frequency generator, 1:24 fanout, 14.318/24/48 MHz outputs.
