It contains two independent PLL circuits, each driving up to 25 outputs from a single 48-TSSOP package. The maximum output frequency is 16 MHz. The spread-spectrum modulation spreads the clock energy across a small frequency band, reducing peak radiated emissions at the fundamental and harmonics. This makes the IMIXG571CTB a direct fit for EMI-sensitive designs: consumer electronics, office equipment, industrial controllers, and any board that must pass FCC or CISPR Class B radiated-emission limits without extra shielding or ferrite beads. ## Supply voltage and temperature grade — what they mean for the BOM The IMIXG571CTB accepts two independent supply ranges: 2.375 V to 2.625 V and 3.135 V to 3.465 V. The operating temperature range is 0°C to 70°C. The 1:25 input-to-output ratio per circuit means a single reference clock fans out to 25 loads on each of the two PLL domains. ## Lifecycle and sourcing For new designs, this means no forced redesign due to obsolescence in the near term. The part is not qualified to AEC-Q100 or any military standard — it is a commercial-grade component.","metaTitle":"IMIXG571CTB Spread Spectrum Clock Generator, 16 MHz","metaDescription":"IMIXG571CTB is an active spread-spectrum clock generator with PLL, 2 circuits, 1:25 fanout, 16 MHz max, dual 2.5 V / 3.3 V supply, 48-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes","Type":"Spread Spectrum Clock Generator","Output":"Clock","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"48-TFSOP (0.240\\\", 6.10mm Width)","Frequency - Max":"16MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 2.625V, 3.135V ~ 3.465V","Divider/Multiplier":"No/No","Number of Circuits":"2","Ratio - Input:Output":"1:25","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"48-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.09","stockQuantity":0,"priceTiers":[{"qty":98,"price":"$3.09000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7abf80c075d02af9154d4ef95fde6e76.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is IMIXG571CTB a direct replacement for other clock generators?","answer":"The IMIXG571CTB is not a direct pin-compatible replacement for the CY2305SXI-1HT. The CY2305SXI-1HT is a single-circuit fanout buffer with a 1:5 ratio and a maximum frequency of 133.33 MHz, and it operates from a single 3.0 V supply.
