It accepts either an LVCMOS reference or a crystal input and generates up to seven LVCMOS clock outputs from a single PLL core that can be bypassed for a clean feed-through path. The 1:7 input-to-output ratio means one reference clock fans out to seven synchronized copies, each capable of running up to 230 MHz. The PLL-bypass mode lets the input clock pass through unmodified when jitter-sensitive paths need the raw source rather than a synthesized frequency. ## Automotive temperature and qualification AEC-Q100 qualification means it has passed the stress tests and reliability monitors required for Tier-1 PPAP submissions — the part ships with the grade documentation a production ECU needs. The supply rail is 1.7V to 1.9V, a narrow window typical of low-voltage clock generators. ## Active lifecycle and sourcing The tape-and-reel packaging (also available as cut tape) suits both high-volume pick-and-place and prototype builds. Store the reels in a dry cabinet — the MSL rating for 20-TSSOP is typically MSL-1 or MSL-2, but the moisture-barrier bag seal should be verified before reflow.","metaTitle":"CDCEL937QPWRQ1 Clock Synthesizer, 230MHz, AEC-Q100, 20-TSSOP","metaDescription":"Texas Instruments CDCEL937QPWRQ1 clock/frequency synthesizer with PLL bypass, 230 MHz max, 1:7 fan-out, AEC-Q100 automotive grade.","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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"20-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":"CDCEL937","Ratio - Input:Output":"1:7","Operating Temperature":"-40°C~125°C","Supplier Device Package":"20-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d2fb79a2215b9689d28226d9ffa109e0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CDCEL937QPWRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum output frequency of CDCEL937QPWRQ1?","answer":"The maximum output frequency is 230 MHz.
