It accepts CMOS or TTL inputs and delivers CMOS/TTL outputs up to 82 MHz. The 1:1 input-to-output ratio means it's a clean clock conditioner — no fan-out, no division or multiplication — just spread-spectrum modulation on a single clock lane. ## Supply flexibility and temperature grade — fit check Dual supply range covers both 3.3V (2.97V–3.63V) and 5V (4.5V–5.5V) rails, so it drops into existing 3.3V or 5V clock trees without a level translator. ## Lifecycle and sourcing posture RoHS non-compliant — verify your assembly house's exemption allowance if you are under full RoHS compliance; this may drive a waiver or a lead-free alternative search. No stock-holding claim; quoted to order against your BOM quantity. ## Package and footprint — 8-TSSOP 8-TSSOP (4.40 mm width, 0.173\" body) surface-mount package — the 0.65 mm pitch is routable on a two-layer board, but a solid ground plane under the PLL core is recommended for jitter performance.","metaTitle":"IMIFS781BTT Spread Spectrum Clock Generator – 82 MHz, Active","metaDescription":"Infineon IMIFS781BTT PLL-based spread spectrum clock generator, 82 MHz max, CMOS/TTL I/O, 8-TSSOP, 0°C–70°C.
