It accepts a clock or crystal input and produces a CMOS output up to 200 MHz. The integrated spread-spectrum modulation helps reduce peak EMI emissions at the board level. ## Supply rail and temperature envelope The part operates from a 3.15V to 3.45V supply — that's a tight 300 mV window, so the 3.3V rail feeding it needs good regulation and low ripple. The commercial temperature grade (0°C to 70°C) restricts it to indoor, non-condensing environments; it's not rated for industrial enclosures or automotive under-hood use. ## Package and footprint Housed in an 8-pin SOIC with 0.154-inch body width (3.90 mm), surface-mount on a standard SOIC-8 footprint. The 1:1 input-to-output ratio means a single clock input drives one clock output — no fanout or multiple synthesised outputs from one package.","metaTitle":"251PMLF Renesas VersaClock® Clock Synthesizer, 200 MHz","metaDescription":"251PMLF Renesas VersaClock® Clock/Frequency Synthesizer with Spread Spectrum, PLL, CMOS output, 200 MHz max, 3.15V-3.45V, 8-SOIC, Active.","metaKeywords":null},"attributes":{"series":"VersaClock®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes","Type":"Clock/Frequency Synthesizer, Spread Spectrum Clock Generator","Input":"Clock, Crystal","Output":"CMOS","Series":"VersaClock®","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Frequency - Max":"200MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","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":"$3.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.62000","currency":"USD"},{"qty":10,"price":"$3.25400","currency":"USD"},{"qty":25,"price":"$3.07680","currency":"USD"},{"qty":100,"price":"$2.66640","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c0dc829947cf4dc14b94bbead3444e77.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the 251PMLF or check availability?","answer":"The 251PMLF is an active Renesas part.
