Accepts LVTTL or crystal reference; delivers up to three CMOS outputs at 200 MHz max. PLL includes bypass mode. Supply range 3.135V to 3.465V — 3.3V plane only. ## Temperature grade and where it fits Rated 0°C to 70°C — commercial temperature range. That puts it in office equipment, consumer electronics, networking gear in a climate-controlled rack, or any indoor PCB where ambient stays above freezing and below 70°C. Not for a motor drive cabinet, an outdoor telecom enclosure, or an engine bay. If your BOM calls for industrial temperature, this isn't the part. ## Package and footprint 8-pin SOIC, 3.90 mm body width, surface-mount. The supplier device package is 8-SOIC — same footprint as a standard SOIC-8. Tube shipment. Store the reels dry if you're buying in tape; the tube is fine for bench quantities. ## Lifecycle and sourcing posture Active lifecycle status per the manufacturer — no end-of-life notice, no last-time-buy window to chase. ROHS3 compliant.","metaTitle":"Cypress CY22381FXC Clock Generator, 200 MHz, 8-SOIC","metaDescription":"Cypress CY22381FXC clock generator with PLL bypass, 200 MHz max, 3.3V supply, 1:3 fanout, 8-SOIC.

That gives you flexibility: use a cheap crystal for a standalone oscillator, or feed a board-level LVTTL clock if one is already available."},{"question":"What is the output frequency range of CY22381FXC?","answer":"The maximum output frequency is 200 MHz. The datasheet covers the full range and divider settings; the PLL can synthesize lower frequencies from the reference."},{"question":"When sourcing CY22381FXC, what's the closest functional second-source — CY2305SXI-1HT?","answer":"The CY2305SXI-1HT is a different part: it is a zero-delay fanout buffer with 1:5 ratio and a 133.33 MHz max frequency, versus the CY22381FXC's PLL clock generator with 1:3 ratio and 200 MHz max. They are not drop-in replacements — different pinout, different function. The CY2305SXI-1HT also carries an industrial temperature rating (-40°C to 85°C) and a different package option. If you need a second source, look for another single-PLL clock generator in 8-SOIC, not a fanout buffer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY22381FXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY22381FXC when reusing this data.
