It accepts CMOS, TTL, or crystal inputs and delivers CMOS/TTL outputs at up to 68 MHz. The 1:2 input-to-output ratio means a single reference clock drives two spread-spectrum outputs, suitable for distributing a low-EMI clock to multiple peripherals on the same board. ## Supply flexibility and temperature grade The device operates from either a 3.3V rail (3.135V to 3.465V) or a 5V rail (4.5V to 5.5V), allowing it to slot into designs with different logic-level supplies without a separate regulator. It is not qualified for industrial or automotive temperature ranges. ## Package and rework — 8-SOIC For reel quantities, confirm the packing option with your sourcing contact. ## Lifecycle and compliance It is listed as RoHS non-compliant (lead-bearing termination finish), which may restrict its use in RoHS-mandated markets unless an exemption applies.","metaTitle":"IMIFS741BZB Spread Spectrum Clock Generator, 8-SOIC","metaDescription":"Infineon IMIFS741BZB — PLL-based spread spectrum clock generator, 68 MHz, CMOS/TTL I/O, 8-SOIC.

The IMIFS741BZB provides spread-spectrum modulation, dual supply range (3.3V/5V), and a 1:2 output ratio. They are not pin-compatible or functionally equivalent for EMI reduction."},{"question":"Can IMIFS741BZB replace a standard crystal oscillator?","answer":"Yes, in many designs the IMIFS741BZB can replace a fixed-frequency crystal oscillator when a spread-spectrum clock is needed to pass EMI testing. It accepts a crystal input and generates a modulated output, but the modulation depth and centre frequency must match the downstream timing budget."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IMIFS741BZB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IMIFS741BZB when reusing this data.
