It accepts a clock or crystal input and delivers up to four HCSL or LVDS outputs at frequencies up to 200 MHz, with the input side single-ended and the output side differential. The 3.135 V to 3.465 V supply range keeps it on the 3.3 V rail common in line cards and switch designs. Spread spectrum modulation is built in — that is the part's main trick for reducing EMI on high-speed serial links without adding ferrite beads or shielding cans. ## 1:4 fanout and differential output — routing the reference clock to multiple endpoints The 1:4 input-to-output ratio means a single crystal or reference oscillator feeds four downstream devices — typically a PCIe root complex plus three switch/endpoint PHYs, or an Ethernet MAC plus three PHY-side SERDES blocks. Because the outputs are differential (HCSL or LVDS), the clock distribution tolerates longer board traces and noisier digital environments than a single-ended CMOS clock. The 200 MHz ceiling covers PCIe Gen1/2/3 reference clock requirements (100 MHz) with margin, and 1000BASE-T / 10GBASE-T Ethernet MAC reference frequencies. The 20-TSSOP package is a compact footprint for the fanout count; no exposed pad to route, so the layout is straightforward. ## Active production, ROHS3 — no LTB risk for new builds The 5V41066PGG carries an Active lifecycle status and ROHS3 compliance. No last-time-buy window, no NRND flag. For a production BOM that needs a PCIe / Ethernet clock source, this part is a clean line item — no end-of-life substitution to plan around. The 0°C to 70°C operating temperature range suits indoor networking equipment, line cards, and test gear; it is not rated for industrial or outdoor extended-temperature enclosures.","metaTitle":"5V41066PGG Clock Generator, 200 MHz, HCSL/LVDS, 20-TSSOP","metaDescription":"5V41066PGG PLL clock generator with spread spectrum, 200 MHz max, HCSL/LVDS outputs, 1:4 fanout, 3.3V supply, 20-TSSOP.

PCIe Gen3 uses a 100 MHz reference clock, and the 5V41066PGG outputs HCSL differential signals up to 200 MHz, so it covers Gen1, Gen2, and Gen3 reference clock requirements with margin. The spread spectrum feature also helps meet PCIe clocking jitter and EMI limits."},{"question":"What output signal types (HCSL/LVDS) does 5V41066PGG support?","answer":"The 5V41066PGG supports both HCSL and LVDS differential output types. The input side accepts a single-ended clock or crystal; the outputs are differential, which is the standard for PCIe reference clocks (HCSL) and many SERDES interfaces (LVDS)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/5V41066PGG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/5V41066PGG when reusing this data.
