It accepts a clock or crystal input and delivers a CMOS output up to 75 MHz. The spread spectrum modulation spreads the output energy across a wider frequency band, reducing peak EMI emissions — useful for passing radiated emissions testing in consumer and office equipment without adding ferrite beads or shielding. The part operates from either a 3.135 V to 3.465 V rail or a 4.5 V to 5.5 V rail. The 1:1 input-to-output ratio means one clean clock in, one spread-spectrum clock out. Temperature range is 0°C to 70°C, which covers commercial indoor environments — office equipment, appliances, test gear, and similar controlled-climate PCBs. Not rated for industrial or automotive ambient extremes. ## 75 MHz maximum — where it fits in the clock tree 75 MHz is the top output frequency. That covers most microcontroller clock inputs, USB full-speed reference clocks, and general-purpose logic timing. ## Lifecycle and sourcing posture That makes it suitable for both new designs and ongoing production replenishment. ## Package and mounting Housed in an 8-pin SOIC package (8-SOIC, 0.154\" body width, 3.90 mm), surface-mount. The supplier device package is also 8-SOIC. No special footprint considerations beyond standard SOIC-8 land pattern.","metaTitle":"W181-53GT Clock Generator, Spread Spectrum, 75 MHz, CMOS","metaDescription":"W181-53GT is an active clock/frequency synthesizer with spread spectrum, PLL, 75 MHz max, CMOS output, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes","Type":"Clock/Frequency Synthesizer, Spread Spectrum Clock Generator","Input":"Clock, Crystal","Output":"CMOS","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Frequency - Max":"75MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V, 4.5V ~ 5.5V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Ratio - Input:Output":"1:1","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-SOIC","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.08","stockQuantity":0,"priceTiers":[{"qty":278,"price":"$1.08000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1b6f7e2dca63899201958200cd10795d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output frequency and voltage range of the W181-53GT?","answer":"The maximum output frequency is 75 MHz.
