What the 552G-02ILNT is and where it fits
The 552G-02ILNT from the ClockBlocks™ series is a single-circuit fanout buffer and multiplexer that takes up to two clock inputs and distributes them to eight CMOS outputs. It handles clock frequencies up to 200 MHz, making it a fit for distributing reference clocks, PCIe reference clocks, Ethernet MAC clocks, or FPGA fabric clocks across a board. The 2:8 ratio means you can select between two clock sources (primary and redundant, for example) and fan out to eight loads without adding external buffers. The supply voltage spans 2.375 V to 5.25 V. The operating temperature range of -40°C to 85°C covers industrial and most commercial environments. The 16-TSSOP package (4.40 mm width) is a surface-mount footprint common in dense mixed-signal boards. The input and output are both single-ended (No/No for differential), so this part is for CMOS-level clock trees, not differential LVPECL or LVDS distribution.
Active lifecycle — no LTB concern
There is no last-time-buy notice or NRND flag. ROHS3 compliant. For new designs and ongoing production, this part carries no imminent obsolescence risk.
