The PLL can be bypassed, letting the input clock pass through directly when you need a clean feed without multiplication or jitter accumulation from the loop. ## Supply rail and output drive The narrow 1.7 V–1.9 V supply means this part needs its own low-noise 1.8 V rail, not a shared 3.3 V or 2.5 V plane. Plan a separate LDO or switching regulator for this supply domain. All nine outputs are LVCMOS — no differential pairs — so the fanout is single-ended. The 230 MHz ceiling is the maximum toggle rate; real-world trace length and load capacitance will limit the usable frequency on a given board. The single PLL circuit (no divider on the feedback path, multiplier enabled) generates the output frequencies from the reference. With a 1:9 input-to-output ratio, one crystal or LVCMOS source feeds up to nine clock loads. Housed in a 24-TSSOP (4.40 mm width) with a 0.65 mm pitch — a common footprint that routes out on a two-layer board without difficulty. Surface-mount only; the tube shipping medium is fine for prototype quantities, but production reels (the PWR suffix variant) are the usual pick for volume assembly.","metaTitle":"TI CDCEL949PW Clock Synthesizer, PLL, 230 MHz, 24-TSSOP","metaDescription":"Texas Instruments CDCEL949PW clock/frequency synthesizer with PLL bypass, 230 MHz max, 1:9 fanout, 1.7V–1.9V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes with Bypass","Type":"Clock/Frequency Synthesizer","Input":"LVCMOS, Crystal","Output":"LVCMOS","Series":"-","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Frequency - Max":"230MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 1.9V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"CDCEL949","Ratio - Input:Output":"1:9","Operating Temperature":"-40°C~85°C","Supplier Device Package":"24-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1303","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c98cafeeb542dbe521bd64606b920517.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between CDCEL949PW and CDCEL949PWR?","answer":"The CDCEL949PW ships in a tube, while the CDCEL949PWR ships in tape-and-reel.
