It accepts LVCMOS or crystal inputs and delivers up to nine LVCMOS outputs, with a maximum output frequency of 230 MHz. ## 1.7V–1.9V supply rail — decoupling and layout The narrow 1.7V to 1.9V supply range means the board must provide a clean, regulated 1.8V rail. Decoupling capacitors placed close to each supply pin are essential to keep PLL jitter under control at 230 MHz. Housed in a 24-TSSOP package with 0.65 mm pitch, this part requires careful fan-out on a two-layer board; a four-layer stack with a dedicated power plane simplifies routing and reduces noise coupling. ## 1:9 output fanout — clock distribution for multi-load systems With a 1:9 input-to-output ratio, this synthesizer can drive nine clock loads from a single reference. The non-differential LVCMOS outputs target single-ended clock trees common in FPGA, ASIC, and processor designs. No official successor or second-source cross-reference is published — this part is the current production choice for the clock-tree role it fills.","metaTitle":"TI CDCEL949PWR Clock Synthesizer, PLL with Bypass, 230 MHz","metaDescription":"Texas Instruments CDCEL949PWR clock/frequency synthesizer with PLL (bypass mode), 230 MHz max, 1:9 output, LVCMOS, 24-TSSOP, -40 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":"Tape & Reel (TR); Cut Tape (CT)","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":"$3.1020","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c98cafeeb542dbe521bd64606b920517.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CDCEL949PWR active or obsolete?","answer":"Active — the manufacturer lists a current product status.
